Why Don't We Just Lower Speed Limits?

I've been waiting to see stories like this pop up in the news media for a long time ... strange that they have been few & far between. So why don't we consider lowering speed limits? Why don't we go back to 55 mph?

As the article points out, there are many benefits:

  • It would save the country millions of gallons of gas
  • It would reduce wear & tear on your car
  • It would reduce the number of accidents
  • It would lower insurance premiums

On a similar note, why is it that cars are capable of moving at speeds north of 100 mph? I mean, if it's never legal to drive that fast, why is it even an option? I understand the need for a car to have power, but have you ever really sat back & wondered why cars can drive triple digit speeds?

It doesn't make a lot of sense. Not nearly as much sense as a 55 mph speed limit. Anyway, go check out the article & the comment thread. It's a pretty interesting read ...

Increasing Energy Awareness Helps

I'm sure a lot of Prius owners feel a lot like this owner:

One of the most fascinating parts of owning a Prius has been the ability to monitor how energy is used and distributed while it is in motion. It also displays the car's current fuel economy as well as the outside temperature. Touching the pad labeled "consumption" brings up a bar chart depicting gasoline mileage. It also shows how much energy has been delivered to the battery. The screens are endlessly informative. And as a new owner, I found my emotions rising and falling by how well I was doing on fuel economy. I felt victorious when the bar would zoom to 100 mpg, deflated to see it drop below 20 mpg.

That seems insightful. As soon as someone becomes aware of their behavior with respect to energy consumption, they want to optimize it (read: save energy). I think there is a market for home energy monitors, as well as monitors for the car too. But I really think it could help in the home. You can imagine programming a monitor to alert you when your consumption hits a certain level. That would be a really great way to keep your consumption capped & your costs down.

I have heard that owners who have a battery-backup solar system tend to watch their battery charge level like a hawk. I'm sure it's the same with grid-tied systems that employ net metering.

The notion to "do better" seems to be hard-wired in humans. I'm sure if we had more energy monitors showing us how much we are using, we'd use less.

Failing the Vision Test

Realize that the energy crisis is fueled by a complete lack of long-term vision.

The average fuel economy of the automobile fleet in the US in 2008 has risen to 20.8 miles per gallon. In 1987, the average was 22.0 miles per gallon. source

Pretty much says it all ... grade: F

The Velorution Hits DC

Washington DC begins a bike sharing program today in a first for the US. Similar to successful programs in Europe (especially Paris), bikes will be available at kiosks placed around the city. The bikes can replace a longer walk or a cab ride for people on the move.

Read the article for all the details, but kudos to DC for making a progressive idea a reality. Not easy to do these days! Some day I'm sure bike sharing will be a standard part of urban life. It makes a ton of sense & should inspire many people to do more riding. A virtuous cycle, no doubt.

The Pope Gets It

From MSNBC:

SYDNEY, Australia - Pope Benedict XVI said Thursday the world's natural resources were being squandered by "insatiable" consumption and urged people to care more for the environment.

I liked Pope Benedict a lot even before I knew he was an enviro-champion. The Pope is so best. Let's hear how he thinks we should counter "insatiable consumption". Seriously, I'd like to hear his point of view.

As for the people who think the Pope is an enviro-hypocrite because he flies around the world in a private plane & rides around in a gas hog (Popemobile), come on! Give the guy a break. He's the Pope!

Utah State Government Moving to 4 Day Work Week

Quick disclaimer ... since I now live in Salt Lake City, when I write about local stuff, it's probably going to relate to the western region.

The governor of Utah has just announced that state workers will switch from a 5 day/8 hour schedule to a 4 day/10 hour week - largely in order to reduce energy consumption (both personal & business). This is set to begin in August ... and it has not been done by any other state. Who knew Utah would be the leading edge of lifestyle changes designed to address the energy crisis? I'm happily surprised.

Obviously, I think this is great news. Getting thousands of state workers off the road every Friday will reduce gas consumption & limit CO2 emissions. It will eliminate 1 full round-trip commute per week for thousands of employees.

This will also get other states looking at similar proposals. It might get some private businesses doing the same thing. All good.

This makes a lot of sense & it shows good judgment on the part of the governor, Jon Huntsman. Will there be some issues with the change? Certainly. Can they be dealt with? Sure. Everyone needs to have an open mind as we begin to rethink the way we commute to work in light of soaring gas prices. Times change & effective leaders change with the times.

Teleworking From Salt Lake City

After nearly a month between posts, I'm happy to be back blogging from a new location. My wife & I just moved ourselves to Salt Lake City & thus far, we are really liking the city, the mountains, the sun, the views & the friendly people!

With a new location comes a new job, right? Well, no actually. My company was kind enough to offer a telecommute situation, so I am now working from home.

I mention this because it means I'll be driving a LOT less than I had been in Albany. I will be flying quite a bit more than I had been, so I'm not sure what his change means for my net energy use, but I plan to do some research on that front. Look for something in a future post on that topic.

The telecommuting has been going well thus far. Since I work "on the web", the work is the same. Obviously the physical isolation is the big change ... that is - no doubt - an adjustment.

Here are some interesting numbers that detail energy savings from teleworking reported by Sun Microsystems on Web Worker Daily:

* The average worker only used 64 watts per hour at home, compared to 130 watts per hour in a Sun office.
* Commuting was responsible for 98% of each employee's carbon footprint.
* Working from home two and a half days per week saves two and a half weeks of commuting time per year.
* The same amount of work at home saves 5400 kilowatt hours of energy per year.

Is the US Getting Serious About Investing in Passenger Rail?

After years of physical neglect & recurring financial woes, it looks like Congress might be starting to comprehend that our passenger rail system is in need of serious help (read: money). While European & Asian countries have long invested billions into high-speed rail systems that typically average over 125mph, here in the US we have Amtrak's Acela running in the Northeast corridor & averaging in the low 80s. Not exactly threatening any land speed records.

Although our train system is pretty much a total national embarrassment (something the Bulgarians would be ashamed of), it's not a total loss ... at least we have plenty of opportunity to improve ;)

New legislation has recently been introduced in the House of Representatives that shows significant sign of life. This is probably the most promising bill I have seen introduced in the past 5 years.

The new bill appropriates about $1.3 billion per year (over 5 years) for Amtrak capital needs. This is the money Amtrak needs to get the system in a state of "good repair". These are the funds the Bush admin has sought to pillage on an annual basis. Locking the funds up for the next 5 years is huge.

Most promising is the emphasis in the new bill on high-speed rail. Rail travel is so much more efficient in terms of energy use that it is inevitable that rail travel will become a much more important means of getting around in future years. Finally, Congressional dingbats leaders seem to have gotten the message (with oil at $125/barrel) that it doesn't make a lot of sense to have tons of people driving from NYC to Boston when they could be riding a comfy (hopefully wifi-enabled) train that sucks down a fraction of the energy all those cars would.

I feel like electrified passenger rail is going to be one of the meta-trends in American lifestyle change in the next 25 years. This bill might be the first step ...

Bike to Work Day 2008

Reminder! May is Bike to Work month, next week is Bike to Work week & next Friday (the 16th) is Bike to Work day.

So, if you have a bike & you're reasonably close to work, consider biking in next Friday. It's good for the environment & the body. Plus, maybe it will inspire others to consider biking in the future.

Kudos to University of Vermont

As an alumnus of the University of Vermont (aka UVM), I am thrilled & proud to see that the new student center (Davis Center building, pictured at right) is the first such building in the nation to be awarded the U.S. Green Building Council's LEED Gold designation.

Here's what it takes to get the LEED Gold label:

Energy efficient design. The Davis Center is expected to use 52 percent less energy than a conventional building of the Davis Center's size. Key energy-reducing design elements include sensors that regulate electric lighting based on the amount of daylight entering the space and air conditioning, heating, and ventilation regulated by occupancy sensors. The building also has a high performance "envelope" of exterior walls and insulating systems; a heat recovery system that uses exhaust air to either pre-heat or pre-cool the fresh air entering the building; and mechanical systems that are designed to fit the precise needs of the space they serve.

Reduced water use. Waterless urinals in the building reduce water use by 41 percent. In addition, the project's landscape design on the exterior of the building and on its storm-water-absorbing green roof feature native plantings, which do not require a permanent irrigation system.

Widespread use of locally harvested and manufactured construction materials. Sixty-three percent of the material used in the Davis Center construction was manufactured or sourced within 500 miles of the site, including the center's 280,000 bricks, which came from the Vermont Brick Company in Highgate, and the 62,000 slate shingles on its roof, which came from Camara Slate in Fair Haven. When there was a choice to purchase from a local manufacturer or distributor or one from outside the northeast region, the university chose to purchase locally, even when costs were slightly higher.

The Davis Center also received four "Innovation in Design" credits for design features and programs over and above those on the application checklist. Those credits include:

A natural smoke evacuation system. The Davis Center's atrium/natural chimney functions as follows: A row of windows on the top floor of the atrium and louvers on the second level open automatically when the fire alarm senses smoke and establish negative pressure that draws the smoke up and out of the space. The system is an example of the university investing in cutting edge design and technology that also saves energy.

An education-oriented building monitoring and display system. Imbedded in the Davis Center are 175 sensors placed in strategic locations to provide data on energy used for heating and cooling, electricity, water usage, and soil moisture, content, and temperature on the building's green roof. Beginning in late February, the data will be displayed on the Web and on a kiosk located in the corridor under Main Street. The monitoring system is designed to educate students and the larger community about the amount of natural resources the Davis Center and its occupants are consuming on a real-time basis. All the data will be logged and will be able to be viewed in several time scales, consumption equivalents, and quantitative comparisons.

Other features that earned the Davis Center LEED credits include interior spaces that maximize daylight, offer exterior views, and eliminate air contaminants; a green landscaped roof to reduce storm water runoff; extensive use of products with recycled content; and recycling of over 92 percent of construction waste by weight, including deconstruction rubble from an existing building on the Davis Center site, which was used as the base under an adjacent roadway and parking lots. The project also earned points for promoting alternative transportation via its pedestrian/transit accessible location, which reduces automobile trips to the facility, the free alternative fuel shuttle bus service serving it, and its encouragement of bicycle use and carpooling.

It's obvious that UVM has put the time, energy & resources behind a truly innovative & highly energy-efficient building. These are important first steps that provide other institutions with the guidance & confidence that they can do the same things. That type of leadership should not be diminished. Then again, coming from a school with an environmentally-conscious student body, faculty & administration, this is just UVM being UVM.

Kudos to Albany Transit Authority

As an Albany, NY resident, I was really happy to spy the news that the CDTA (Capital District Transit Authority) is planning to convert all city buses to bio-diesel, and while browsing their website, came across this page which details all of the energy-saving stuff happening over at CDTA.

CDTA estimates that the switch to bio-diesel will save "about 125,000 gallons of diesel fuel next year [2008]." Nice to know that energy conservation is top of mind for the local transit authority.

Other neat initiatives at the CDTA include:

Progressive public transit ... way to lead by example CDTA!

Top 10 Green Ideas in 2007

Time has posted a bunch of top 10 lists, including the Top 10 Green Ideas list. Here's how they see things:

  • The Intergovernmental Panel on Climate Change (IPCC)
  • The U.S. Climate Action Partnership (USCAP)
  • The Green Supply Chain
  • Avoided Deforestation
  • Green-Collar Jobs
  • Plug-in Hybrids
  • E-Flex
  • Congestion Pricing
  • Carbon Capping
  • Geo-engineering

I would have liked to see these ideas:

  • Live closer to where you work
  • Virtual office
  • 4 day work week
  • Walkable neighborhoods
  • Tax credits for residential solar

Time's list doesn't ask the reader to change behavior. It implies that "Green Ideas" are going to rescue us from our energy problems. Not really, but I guess it reads well ...

Google Pushing Renewable Energy

I've written about Google's renewable energy efforts once or twice in the past. And now it sounds like Google is further ramping its commitment to renewable energy research and development.

Google is taking a leadership position on low-cost renewable electricity generation that can scale. Specifically, Google is going to try to produce electricity from renewable sources at rates competitive with current coal-fired electric plants.

Our goal is to build 1 gigawatt of renewable energy capacity that is cheaper than coal. We are optimistic that this can be done within years, not decades. If we succeed, it would likely provide a path to replacing a substantial portion of the world's electricity needs with renewable energy sources.

Google, as they note, has some experience building out energy efficient data centers ... and they clearly have a vested interest in locking down or reducing energy costs. However, Google is a web technology company and not a renewable energy company, so it remains to be seen if they can come close to hitting their rather ambitious goal noted above.

Obviously, this is excellent news regardless of whether the specific goal is met or not. It means that one of America's most innovative companies is now moving with speed and with big money to attack one aspect of our energy problems. Since I have no faith at all in our government to solve difficult problems, it is great to see Google take the reigns. Though I'm skeptical of solar thermal or wind power to scale to meet the level of demand that exists, this is still a big win for fans of RE.

Good luck, Google!

Energy and the 2008 Election

I caught part of the Democratic debate on cable a couple of nights ago and was pleased to hear the candidates talking about energy. Even in the 2004 election, with the Iraq War in full swing, energy didn't really make it to the national level as a political issue. When you consider that the war is being fought on top of billions of barrels of oil, it's pretty incredible that it didn't become a flashpoint. C'est la vie. It's now on the table and my guess is that energy will become a critical issue in the 2008 election. With oil marching towards $100 per barrel and gas once again approaching $3 per gallon and no sign of an ease in global energy demand or a rise in global energy supply ... people are starting to wake up to reality.

The Consumer Federation of America released a new report and survey results that show Americans are beginning to understand that high energy prices are not temporary. The report found:

  • Over the last five years, household energy expenditures (home heating and gasoline) have nearly doubled, and are now 50 percent more than health care expenditures and 23 percent more than spending on food.

  • Three key energy provisions bottled up in Washington could save consumers more than $180 billion between now and 2020.

The survey results included the following points:

  • Concern over U.S. dependence on oil from the Middle East has grown dramatically and now almost equals concern about prices. Seventy-six percent of those asked express concern over imports (56 percent express great concern).

  • An overwhelming majority (84 percent) supports three requirements in Congressional energy legislation: l) higher fuel economy standards for passenger vehicles; 2) the purchase of renewable energy by electric utilities, and 3) expanded production of biofuels.

  • An overwhelming majority (75 percent) still supports these proposals after hearing arguments from opponents of the legislation.

  • Opposition to these policies is meager (between 13 and 22 percent).

This report/survey shows that the average consumer has already transitioned mentally to a new reality. As has happened many times in the past, the people in the US are way ahead of the representatives on the issue. In a year, the American people aren't going to put up with a candidate who is not saying the right things about energy. It's time for the leadership to wake up and catch up ... ASAP!

Testing New Bike Lanes in NYC

New York is not only testing new battery-powered buses ... they are also doing some progressive work with street redesign on 9th avenue. They have reworked a section of the avenue so that there is a buffered bike lane next to the sidewalk on one side of the street. The buffer? Parked cars.

Here's a picture below ... and you can read more about the experiment at the NYTimes.

The first comment that was made under the article said:

As a longtime resident of 22nd St. & 9th Ave., I am amazed with the improvement of 9th Ave. Traffic is flowing like normal, but cars seemed to have reduced their speeds on their own. Delivery guys on bikes are no longer running you over from all angles, and you know exactly where to look for them. The overall layout of the “new” 9th Ave. feels clean, organized, and well thought out.

Only one person's opinion, of course, but sounds pretty effective. I was recently down in New York and I can tell you that a bike lane like this would definitely encourage me to get on the bike a lot more often. The status quo is most definitely not bike-friendly. There is great stuff happening in New York around conservation and smarter energy use. I dig it.

New York's New Battery Bus

Check out the new test bus running around midtown Manhattan these days. It's battery powered (though the battery is charged by a diesel engine with help from the brake system a la Prius) and gets better mileage than the city's fleet of current hybrid buses:

Jerry Higgins, the director of new bus technology for New York City Transit, said the manufacturer predicts the bus will get about seven miles per gallon, which is about double the fuel efficiency of the transportation authority’s current hybrid bus fleet.

Nice to read some good news every once in a blue moon ...

Summer Travel Gridlock - Who Needs It?

I read a story like this about the horrors of summertime travel that many of us have experienced firsthand ... and I wonder why these experiences and these problems don't dissuade people from flying. In fact, the opposite is happening:

But with the lure of low fares and the lust for travel, Labor Day fliers will not be deterred, however. The Air Transport Association says 15.7 million people, a 2.6 per cent increase over last Labor Day weekend, will fly U.S. airlines between Aug. 29 and Sept. 5.

What keeps them coming back for more, I wonder? Why aren't they turning away from the airports and their frustrating wait times, cancellations, security checks, lack of communication, and piss-poor customer service? Cheap flights? Is it that simple?

The air system is clearly at its break point during the heavy travel summer season. Last place I want to be on Labor Day weekend is anywhere near an airport. Reminds me of a famous Yogi Berra quote:

Nobody goes there anymore because it's too crowded.

That's how I feel, Yogi. Apparently most Americans don't share that sentiment. Bizarre ...

Fastest Way to Reduce Energy Use and Save Money

You're concerned about the environment and about the amount of energy you personally consume. You are thinking about reducing your carbon footprint. You are serious about changing something about your behavior, and you want to do something bigger than running down to Home Depot to grab some compact flourescent light bulbs for the house. But you aren't sure what you should do ... and you need some guidance.

Here's the simple solution: sell your car and replace it with a car that gets better fuel mileage.

I did it almost exactly one year ago, and it has been a great decision. I now go around telling everyone to do the same thing, so I might as well tell you about it too.

In my case, I swapped my Nissan Pathfinder SE for a used Honda Accord. Just like that I went from driving a vehicle that averages 15mpg (city + highway combined) to one that averages 24mpg. If I drive the Honda 13k miles this year, I'll be saving 325 gallons of gas. At $3.00/gallon (NY has a pretty steep gas tax), that's $975 dollars in my pocket. That's a pretty significant chunk of change.

I also obviously reduced the amount of harmful emissions I was producing by driving my car. FuelEconomy.gov tells me I am expelling about 4.5 fewer tons per year by making the switch from SUV to sedan. That feels good.

I loved the Pathfinder, but I could no longer overlook the fact that it was a total gas hog. Long drives from Albany, NY to family in Boston, Long Island, New Jersey and Connecticut and to vacations in Montreal, Vermont, New Hampshire and Maine were becoming more and more expensive as gas prices hit $3.00/gallon territory.

Sure, I miss being perched higher up on the road and I miss the security that comes from shift on the fly 4 wheel drive during winter snowstorms. But let's face it - those are luxuries I can manage without. I hear a lot of people say they drive a big SUV because they need the space. I think that's BS. The Honda packs very well and has bigger trunk room than would appear. Other than moving furniture, the Honda meets my space needs really well.

So, if you want to reduce your energy use, save a substantial amount of money and do the right thing for the environment, replace your car. Very simple. If you're already in a small, fuel efficient car, kudos for choosing wisely and responsibly!

Hearst Tower: Tall, Faceted and Green in New York

In late 2006, a new energy-efficient building opened in mid-Manhattan called the Hearst Tower (pictured at right).

This tower has subsequently been awarded rated "Gold LEED" by the United States Green Building Council. This was the first building in New York city to achieve the Gold status.

What exactly is LEED? From the USGBC's website:

The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ is the nationally accepted benchmark for the design, construction, and operation of high performance green buildings. LEED gives building owners and operators the tools they need to have an immediate and measurable impact on their buildings’ performance. LEED promotes a whole-building approach to sustainability by recognizing performance in five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality.

The highest level of certification is Platinum, so the Hearst Tower apparently could have been just a little bit greener ;)

Anyway, the building is well ahead of its time. Here are some of the energy saving characteristics:

Hearst settled upon an innovative "diagrid" system (a word contraction of diagonal grid), that creates a series of four-story triangles on the façade. No verticle steel beams are being used, which is a first for North American office towers. In addition to giving the tower a bold architectural distinctiveness, it is providing Hearst with superior structural efficiency. As a result, Hearst eliminated the need for approximately 2,000 tons of steel, a 20 percent savings over a typical office building.

Hearst executives also selected an innovative type of glass that wraps around the exterior of the building. The glass has a special "low-E" coating that allows for internal spaces to be flooded with natural light while keeping out the invisible solar radiation that causes heat.

In conjunction with the glass, Hearst is installing light sensors that will control the amount of artificial light on each floor based on the amount of natural light available at any given time. The optimization of natural light has been demonstrated in recent studies to have important, positive effects on occupant health, quality of life and productivity.

Hearst also will utilize technology that senses activity level. At lunchtime, when some employees are leaving or not using their computers, motion sensors will detect this and adjust the system accordingly. These sensors will allow for lights and computers to be turned off when a room is vacant.

In addition, Hearst is using high efficiency heating and air-conditioning equipment that will utilize outside air for cooling and ventilation for 75 percent of the year, as well as Energy Star appliances. These and other energy-saving features are expected to increase energy efficiency by 22 percent compared to a standard office building. This is a welcome innovation in New York City, where rapidly growing electricity demand is threatening to overwhelm the local power supply.

Hearst is also employing pioneering technologies in order to conserve and more efficiently use water. For example, Hearst's roof has been designed to collect rainwater, which will reduce the amount of water dumped into the City's sewer system during rainfall by 25 percent.

The rainwater will then be harvested in one 14,000-gallon reclamation tank located in the basement of the Hearst Tower. The rainwater will be used to replace water lost to evaporation in the office air-conditioning system. It also will be fed into a special pumping system to irrigate plantings and trees inside and outside of the building. It is expected that the captured rain will produce about half of the watering needs.

The harvested water also will be utilized for "Icefall," a three-story, sculpted water feature within the building's grand atrium. In addition to serving as a stunning entrance to the building, Icefall, which is believed to be the nation's largest sustainable water feature, will also serve an environmental function by serving to humidify and chill the atrium lobby as necessary.

I wish we heard more about these types of developments ... and although this is old news, I thought it deserved a write up. Hope you did too.

Calculate Your Walk Score

How great is it when you find a new website that provides a truly unique (and useful) service for free? Pretty freakin' great, right? Well, check out Walk Score ... it is a diamond in the knee-high rough that is the Internet.

What is Walk Score?

Walk Score helps people find walkable places to live. Walk Score calculates the walkability of an address by locating nearby stores, restaurants, schools, parks, etc.

Walk Score is very simple. You punch in your address and click submit, then the site queries Google Earth to find stores, restaurants, schools, theaters, etc. near your address. Using its proprietary ranking algorithm, Walk Score calculates a customized score somewhere between 0 (you can't walk to anything but your car) and 100 (walk nirvana).

I just noticed that the site is currently not functioning because it is over its Google Maps quota, but when I tried last week, I scored a dismal 18. I live in Albany, NY - but not near the downtown area. Other than a small park across the street, we have nothing closer than 0.6 miles away from our door. Seems like a half mile is a critical marker for Walk Score's algorithm. If you have stores & restaurants within a half mile, you are likely to score above 50.

If you visit the site and can't run your score, try back in the morning the next day. The Google Maps quota resets daily.

I have Walk Score bookmarked. An invaluable resource when considering relocation. Great stuff!

Shut Down Your Computer

Want to save some energy and reduce your electric bill? Shut down your computer when you're not sitting in front of it. Pretty basic notion ... but apparently a lot of people leave their computers turned on overnight - especially their work computer. The Wall Street Journal is reporting:

A recent report estimated that American businesses could save $1.72 billion each year merely by getting more employees to shut off their computers at night or allow the machines to enter an energy-saving mode.

I never leave my laptop at home powered up overnight or when I'm not using it, but I do leave my work computer turned on when I leave for the day. (On Friday afternoons, I usually shut down for the weekend.) Not sure why I leave it turned on overnight ... I think it basically boils down to laziness and the fact that I'm not responsible for paying for the electricity I consume at work. There must be a creative way for companies to incentivize employees to shut down every night. Maybe a conservation drive. Compare year over year energy use and if it is lower in the current year, everyone gets a Starbucks gift certificate or some other small token. Just a thought.

And if there are concerns about the wear and tear associated with lots of shut-downs & power-ups, those can be put to rest:

Several commenters on blogs and the Register suggested another possible reason to leave computers on: Switching them on and off drains energy, and may cause damage. Several energy experts told me that doesn’t apply to today’s machines, for which the amount of energy saved by switching off dwarfs the amount consumed during the booting process. “PCs are not hurt by turning them on and off a few times a day,” said Jonathan Koomey, a project scientist at the Lawrence Berkeley National Laboratory. “Economic obsolescence is much more dangerous to PCs than turning them on and off.”

Shut down your work computer before you call it a day. It can't hurt.

Hummer Attacked

In early June, I blogged about how someone at my office was driving a new Hummer to work. At the end of the post, I wrote the following:

I have a prediction. Those middle fingers won't be proudly displayed much longer. There will come a point in the not-too-distant future when driving an H2 will be embarrasing. H2 owners will have the option of spending an afternoon in the stockade or wearing a beige sweater with a massive yellow "H2" nylon patch sewed onto it, Hester Prynne style.

Turns out I wasn't too far off in that prediction. A Washington Post article today tells us about 32 year old Washington DC resident Garreth Groves and his new gray Hummer:

It [the Hummer] lasted five days on the street before two masked men took a bat to every window, a knife to each 38-inch tire and scratched into the body: "FOR THE ENVIRON."

Anti-Hummer vigilantes? Interesting ... Expect to see more of this stuff going forward.

Also, the reason Mr. Groves was inspired to purchase his now vandalized gas guzzler?

Groves, who grew up in the District and works in marketing for a local radio station, said he wanted the car in part because he is starting a company, Washington Sports Marketing, that is "image-based."

"Image-based". Puke.

Amtrak In Jeopardy ... WTF?

When I read this article detailing Amtrak's financial and budget woes (even though business has been brisk of late), I felt so frustrated. Here we have oil prices reaching historical high levels (WTI at more than $74 per barrel as I write this) and an administration trying to slash funding for passenger rail.

According to Amtrak CEO Alex Kummant, the system could keep operating if the congressional legislation, expected to pass sometime in September, evades a promised veto. But (President) Bush, never a friend of Amtrak, says he’ll nix any bills that exceed his budget requests.

Got to hand it to good ole George dubya ... he really knows how to run a country right into the ground, in the most efficient manner possible.

If forced to slash service, everything outside the busy northeast corridor (Boston-New York-Washington) could be in jeopardy. That would mean elimination of all passenger train service in the west, midwest, and south – creating a much heavier demand on an airline industry that is already stretched to the breaking point.

Perfect! Let's put more strain on refiners to produce more jet fuel to meet rising airline fuel demand. That should also help with the climate change issue. Somebody wake me up on 01.29.09 ...

Create Your Own Offsets

Now that Live Earth is behind us, hopefully we will stop reading about how counter-productive the concert series was in terms of energy waste. Yes, a lot of carbon was burned in order to produce the massive shows and yes, that includes a lot of air travel. I personally think it's justified given that the concert focused some high-profile attention on a global problem in an effort to wake people up and (hopefully) start to get people interested and invested in doing something about climate change.

Still, Live Earth left me with the same feeling I had after watching An Inconvenient Truth: the feeling of not being sure what to do next. Several times I heard advice like: replace your lightbulbs or recycle more. The focus seemed to be on the easy, really small stuff. Come on, Cameron Diaz - that's not going to get it done.

The concerts may have been better served by unifying the experience in a slogan that people could digest and go home with. Something like "create your own offsets". Carbon offsets are pretty controversial because they are basically like the old Catholic indulgences, where the faithful could literally pay to have sins cleansed from their record. Today, the person who flies from New York to LA can purchase carbon offsets, leading to a global warming-free conscience.

Of course, we don't really know whether carbon offsets actually offset all or any of our activities.

So how about "create your own offsets"? For instance, if you have a trip coming up and you're flying somewhere, why not make a point to walk to the store half the time - instead of driving all the time? Every time you walk instead of drive, you have just banked some credits to offset your upcoming trip. If you are going on a big road trip, stop watching the TV until the trip. Bank some credits to offset your gas guzzling.

Chances are, creating your own offsets would end up being a lot easier and fun than it maybe sounds. Make a game out of reducing your energy use. See how many credits you can bank. Think before you jump into the car or book that next flight. In the long run, those are the types of changes that will make a difference, because it mandates some thinking about your relationship to the world around you in the context of energy use and climate change. It's too simple and cheap to point to CFLs and be satisfied. Real progress will require real change ahead.

the iPhone and Energy

The iPhone is a truly innovative communication tool. Since buying it on Saturday, I have been amazed by its capabilities and great design. On a hike in the Catskills on Sunday, my fiancee mentioned that she thought I should blog about iPhone. At first, it didn't seem relevant to energy ... but the more we talked about it, the more we realized that iPhone can potentially save energy and help people reduce their energy footprint.

Here's what I'm thinking ...

iPhone can be charged by the sun
I have blogged about an awesome little solar charger before ... and it dawned on me that - if someone wanted to - the iPhone could be run exclusively from solar power via a charger like the Solio. While it may not be practical to run iPhone off sun power, it nevertheless exists as a possibility and that's what is important. Small solar chargers are going to continue to become more popular and have more impact on our lives. That's a good thing.

iPhone saves paper
iPhone is tightly integrated with the Internet and, in particular, with Google Maps (a wonderfully useful tool in its own right). Whenever I'm about to embark on a road trip to a new location, I usually punch up directions in Google Maps and then print those directions out. About 3 out of every 4 times, the directions print out on 2 pages when 1 would have seemed sufficient. This must be due to the fact that the web page does not translate well to print. Anyway, iPhone eliminates the need to print out directions since you can view them - step by step - on the phone. Hell, you don't even need to deal with punching up directions on your computer at all, since iPhone can access the Internet from anywhere over the Edge network. If my calculations are correct, iPhone could save a billion pieces of paper per year. Then again, I haven't done any calculations, so take that with a grain of salt.

iPhone's map feature saves fuel
Speaking of how the maps saves paper, it also saves fuel. Armed with the hard copy directions, you still invariably find yourself lost when traveling in your car. Now that you can punch up an address and get directions with iPhone ... you will get where you're going quicker. Less time on the road means more gas in the tank. Really, iPhone is this good.

iPhone helps you avoid parking lots
And by parking lots, I mean the kind that form around rush hour on interstates and highways. The map widget (application-?) - whatever you call it - has this neat button that looks like a car. After you punch in your location to get directions, you can tap the car to get real-time (remember, you're networked to the www) updates on traffic. How useful is that? Not only will this save you from the horror that is the highway traffic jam, it will save gas, too. Just ask BankRate.

iPhone reduces computer time
I'm already spending less time in front of my laptop at home ... because of the iPhone. For quick hits like checking email or checking scores or getting quick directions, the iPhone delivers. Which means I no longer need my computer for those things. Which means my computer will not be sucking down watts (I never keep the computer running unless I'm working in front of it.)

So there you have it. In just a matter of hours, the iPhone has already contributed to a reduction in my energy use/footprint. I'm sure as I get more comfortable with it, I will uncover additional tricks that lead to energy savings. Thanks, iPhone!

Yvon Chouinard of Patagonia

I've long been an admirer of Patagonia. They produce top-shelf outdoor gear and have probably the sickest print catalogs in the world - visually stunning and loaded with interesting editorial content, plus all the fantastic gear-browsing. (My only knock on Patagonia is the sorry state of its website. Google-friendly, it is not!)

Yvon Chouinard (pictured at right), founder of Patagonia, is unique in the world of business because he puts environment ahead of profit and growth. An interview with Yvon is available in the July 2007 issue of Mens Journal, and some of his comments were striking. For example ...

Mens Journal: But global warming is a "hoax." Yvon: Well, I tell you, these people who say we have 10 years to turn it around - you know what? It's too late. And I see it. Oh, my God, it's unbelievable.

Mens Journal: What have you seen?
Yvon: I've been going up to British Columbia for 30 or 40 years, and all the little pocket glaciers on the coast range have receded. They have withered down to two-thirds the size of what they were. And you can see it very dramatically because you can see the lichen line. It's pretty serious. I think British Columbia's going to lose all the salmon streams as a result, because they've done everything wrong. They've clearcut all the rivers, so there's no shade. And those little pocket glaciers are really important for trickling down cold water all summer long. Now the summer water temperatures are getting up in the 70s, which is death for salmon. So probably the only places in the world that'll have salmon are Alaska and Russia. I'm not talking 50 years from now; I'm talking right now. When I go salmon fishing I look at myself as witnessing the end of a species.

Mens Journal: You've made no secret of trying to wean Patagonia off oil. Is that in response to climate change?
Yvon: Outside of global warming, the end of oil is the biggest thing that's going to happen. It's going to happen within our lifetime. We're running out of petroleum. So to my management I said, "Okay, what is going to be our response as a company?" If we avoid talking about it, then we end up like General Motors and Ford, which have had their heads in the sand for so long. And there's Toyota laughing all the way to the bank. So we've made a commitment to make, by 2010, every single piece of clothing out of recycled and recyclable fibers. If we want to do something about global warming - Sweden and Iceland said no petroleum by 2020, zero - that's what you've got to do to really have an effective response. The idea of, Oh, well, we'll all be driving hydrogen cars and blah, blah, blah, you know, electric cars - well, it takes energy to produce that hydrogen and that electricity. It takes more energy to produce ethanol than you get out of it. If it weren't subsidized to death, nobody would be making gasoline out of it. And with people starving around the world - I mean, it's stupid to be making gasoline out of food. And having put in $2 million worth of solar panels that produce only 12 percentof the electricity that we use here at the headquarters, I know for a fact that that's not a very efficient system.

Mens Journal: You've just dismissed out of hand almost every alternative to fossil fuel there is. Do you have a better option to recommend, or is it really down to reducing consumption?
Yvon: That's the main thing we have to do. If we insulated all our houses and put in triple-pane windows and stuff like that, it would save a tremendous amount of energy, and it would stall the end of oil for a while. But ultimately we're going to have to go back to a very simple lifestyle, and it's going to be the end of globalism, basically. For us as a business it's pretty scary, because we produce organic cotton in Turkey, and then we shit it to Thailand to be made into cloth, and then it's cut and sewn in Mexico, then sent to Reno, Nevada, to the warehouse, and then shipped from the warehouse to our dealers and to our shops. Man, the transportation costs of that are going to be more expensive than the product in a very short time.

Mens Journal: You've been talking about the need for business to clean up its own act for years. Is it gratifying that others finally seem ready to change?
Yvon: It's amazing how quickly it's happening now. It really is. It's out there, that we need to act, and we can't wait for government. I get calls every day asking me to talk to this group or that group. I'm going to talk to United Artists next. A friend of mine at Fox Sports told me that even Rupert Murdoch told his staff they need to have a green plan. And what's interesting is that it's not a political thing; it's for different reasons. Some companies see that there's money to be made, but a lot of companies are realizing that global warming is deadly serious for the future - that there's money to be lost. Business people get that we can't wait for the government; it'll be too late. Even the states see that. So these companies, a lot of them have no idea where to start, so they look at us having been there, having taken the risk. But what we've always wanted to show is that it's not a risk to protect the environment. The risk is when you don't.


Yvon sounds quite a lot like James Howard Kunstler in these comments, but then again he seems to realize the market system is beginning to respond and change to fit the times. An interesting hybrid to be sure. I agree that there is not going to be a silver bullet fix to the peak oil problem. We'll use wind, solar, ethanol, biofuels, etc. But the biggest savings, as Yvon states, will come from conservation. The amount of waste in the system is staggeringly high. I think the pessimists underestimate the level of waste. Conservation will become hip and cool. Driving around in Hummers will become dangerous to one's reputation and health. Patagonia is super-smart to be switching now to capitalize on this shift in psychology and mindset, and is lucky to still have Yvon around as a guiding light. What an interesting, inspiring leader.

Google Charging Up

I've written before on this blog about Google's solar energy initiative and most people are aware that Google is way ahead of the curve when it comes to big business and renewable energy. But I had no idea how deeply Google is involved in renewable energy research, via Google.org.

I just stumbled across this article about Google's promotion of plug-in hybrids, which led me to Google.org and all sorts of neat stuff.

Check out Google's solar system page - it tracks the output of the system. I think it just went live. Very cool!

There are other fun, interactive pages on those websites ... too much to set individual links. Definitely worth a few moments poking around. Fantastic stuff from a legendary company ...

Hypermiling Makes Driving Fun

I've been seeing random news items for the past few months (since gas prices approached and passed the $3/gallon mark) about hypermilers and hypermiling. What is it? It's a host of driving techniques that combine to increase a vehicle's fuel efficiency and reduce gas consumption.

Hypermilers practice the following tricks of the trade:

  • avoid jackrabbit starts
  • avoid hitting the brakes
  • drive with the windows up
  • drive 55-60 mph on the freeway
  • avoid traffic congestion
  • park as close to the exit as possible at stores
  • park at the high point of a parking lot
  • shift into neutral on downhills and coast
  • keep your tire's pressure up to reduce friction with the road
  • reduce the weight of the vehicle by clearing out the trunk/backseat of junk
  • use super-thin motor oil in the vehicle
  • change the motor oil more often
  • replace the vehicle's air filter
  • attempt to "time" lights so the vehicle does not come to a complete stop
  • keep the car washed to reduce drag
  • draft larger vehicles on the highway
There are more things that hypermilers do to get better efficiency ... I just don't know about them yet.

I've been hypermiling for at least 2 years. I rarely drive above 60mph on the freeway and I'm very conscious about how much pressure I use on the gas pedal. I've always been the type of person who likes to "time" the lights, and I find myself parking in a central part of a stripmall parking lot and walking to each store (as opposed to driving from one end of the complex to the other). There are tons of little things you can do to get better mileage ... I like to look at hypermiling as a challenge. It's fun to try and squeeze more out of the car and it's fun to save some pennies while doing it.

FU, H2

Someone at my company must have recently bought or leased a Hummer H2. It's taxicab yellow. Pretty tough to miss. I can't help but wonder, "Why would any person of sane mind want to drive a taxicab yellow Hummer to a desk job?" The mere sight of this H2 makes me ill ... like when I saw Magda's boobs in Something About Mary.

Not good.

I'm going to assume the sight of his or her new H2 in the driveway doesn't elicit images of Magda, so you have to wonder: What motivates this person?

Can't be the fuel economy. The H2 gets 13mpg on the highway and 10mpg in the city. Depending on the driver and driving style, the H2 can get as low as ~8mpg. That thing is gonna kill your transportation budget with regular over $3/gallon.

It's obvious the H2 owner could care less about spending money on gas.

Maybe the person is an off-road junkie on the weekends. If so, perhaps there's a valid reason to own an H2, though I think it's still stupid to drive it into work. (If you have enough money to blow on a Hummer, why not take some of that cash and buy a smaller car for use during the week?) Plus, the H2 at my office is looking spotless. Not a drop of mud on the thing since it started rolling in.

Then again, the person who drives the H2 is likely so enamored with the thing that you can imagine over-zealous car washing is probably fairly common - especially when the car is new.

Regardless of what fires this person's neurons (I don't want to get into psychological needs/desires/esteem angle), it's probably pretty safe to assume the H2 driver doesn't think much about personal carbon footprint or environmental responsibility.

I find that mind-boggling. Global warming news stories are nearly ubiquitous these days. Hell, even George W. Bush is now acknowledging that we need to deal with the environment/energy double-edge sword. Candidates for President are almost universally talking about the need to increase fuel economy in our auto fleet. And then there's the recent purchaser of our banana peel yellow H2 who is currently giving a middle finger to the Earth.

I have a prediction. Those middle fingers won't be proudly displayed much longer. There will come a point in the not-too-distant future when driving an H2 will be embarrasing. H2 owners will have the option of spending an afternoon in the stockade or wearing a beige sweater with a massive yellow "H2" nylon patch sewed onto it, Hester Prynne style.

H2, FU!

Need Another Fix. Just One More Fix.

In a post last week that discussed a survey showing that Americans think we have a LOT more oil in the US than we actually do (we actually have less than 3% of total proved world oil reserves), some commenters mentioned that we have billions of barrels trapped in shale rock and therefore we have more reserves than the 3% of proved figure would indicate.

This is madness. The oil shale reserves, if you can call them that with a straight face, are not liquid. They are hydrocarbons trapped in rock. In order to turn them into liquid, you have to apply lots of heat to accelerate the reaction process that occurs over millions of years in nature.

A Denver Post article explains how low oil companies (and by extension, the American people who drive demand) are willing to go to get another massive oil fix:

Chevron scientists are working with researchers at the Los Alamos National Laboratory in New Mexico to determine which chemicals work best for converting shale to crude oil.

Shell engineers are burying hundreds of steel rods 2,000 feet underground that will heat the shale to 700 degrees Fahrenheit, a temperature at which Teflon melts.

The heat will be applied for the next four years to convert the hydrocarbons from dead plants and plankton, once part of a prehistoric lake, into high-quality crude that is equal parts jet fuel, diesel and naphtha, the main ingredient in gasoline.

Irving, Texas-based Exxon Mobil plans to shoot particles of petroleum coke, a waste byproduct of oil refining, into cracks in the shale. The coke will be electrically charged to create a subterranean hot plate that will cook the shale until it turns into crude. The company declined to discuss the progress of its oil-shale tests.

Raytheon Co., the maker of Tomahawk missiles and the first microwave ovens, is developing a process that would use radio waves to cook the shale.

I'd love to know what type of energy input it would take to inject and then heat hundreds of steel rods deep underground for four years. Oil shale is totally unproven and appears to be completely and utterly insane. What's most disgusting though is the tone of the article. It doesn't question the logic of heating shale in situ over the course of years. It doesn't stop to ask: Is this the best option? It just wraps up with a blurb about potential ROI bla bla bla.

Sick.

Drivers Cut Back, Ultimate Garbage Oven

The New York Times Magazine last Sunday was all about the environmental movement. The elite are going green ... too bad the herd hasn't caught on yet.

The McPaper is reporting that drivers cut back on the number of miles driven for the first time in 26 years! The reasons for the downshift? They cite soaring gas prices, re-energized urban communities, and old people. Huh?

Interesting piece about a NASA-developed plasma torch oven that cooks garbage to more than 10k degrees F and outputs gases that can be used to power turbines and produce electricity. Shit fire! But wait ... what powers the 10,000 degree plasma torch? Flux capacitor?

And finally, pretty neat looking rain catch barrels from a dude named Aaron. Love that Whisky Barrel. If you're in the market and looking to conserve use of water, this site is worth checking out.

Should I Even Care About My Carbon Footprint?

Lately, I've been thinking a lot about personal carbon footprints. In my own case, my footprint is probably below average ... I rarely fly, I commute 12 miles one way in a Honda Accord, and I make an effort to use public transportation when possible. I also like to cycle and think walkable communities make great sense for both reduction of energy consumption and improvement of personal health.

When that news came out about Gore's electric bill a few months back, I was pretty pissed. I understand that an international figurehead like Al Gore is going to burn through a lot of fossil fuel as he globe trots - he is spreading the global warming message so that seems like an acceptable trade. But, at the same time, it doesn't sound like he's made a personal commitment to lowering his carbon footprint outside of his public, professional life. That rubs me the wrong way.

I recently booked honeymoon tickets for Hawaii and I actually felt a twinge of guilt because I thought about the huge amount of jet fuel those flights would consume (New York to Phoenix to Hawaii). On the other hand, my guilt strikes me as pretty unwarranted. In the grand scheme of things, my honeymoon trip isn't going to make an ounce of difference. Maybe. Or maybe not? Hard to know.

Well, after reading this Forbes article about ChIndias ever-increasing appetite for coal-fed power plants, I think I have a better sense for the answer.

Here's a few lines from that report, if you don't feel like clicking through ...

Coal consumption in China and India is forecast to increase by 3% a year between 2006 and 2030, compared with an increase of 0.6% a year for the developed countries that belong to the Organization for Economic Cooperation and Development, according to S&P analysts.

India doesn’t believe it has contributed to excessive greenhouse gases and wants developed countries to explicitly address the issue before it does anything, the report says.

Much of its expected growth will come from the Indian government's plans to add about 100,000 megawatts to the country's existing installed capacity of about 140,000 MW to meet its goal of "power for all" by 2012. "To meet this target, the government has proposed at least seven coal-fired ‘ultra-mega power’ projects,” S&P said.

Yeah ... I don't think I really need to worry. Maybe Gore was onto something.

Top 10 Green Buildings of 2007

The American Institute of Architects announced the top 10 green buildings in 2007 winners recently.

The 2007 COTE Top Ten Green Projects program celebrates projects that are the result of a thoroughly integrated approach to architecture, natural systems, and technology They make a positive contribution to their communities, improve comfort for building occupants, and reduce environmental impacts through strategies such as reuse of existing structures, connection to transit systems, low-impact and regenerative site development, energy and water conservation, use of sustainable or renewable construction materials, and design that improves indoor air quality.

Visit the link above to read a detailed description of each project. A few neat examples follow below:

  • Solar chimneys with south-facing glass are designed for passive ventilation, operating without additional energy. Sunlight heats air within the glass chimney tops, creating a convection current which draws cooler air into the building through north facing open windows.
  • The 30,000 square foot green roof with glazed bubbles floods the facilities below with daylight.
  • There is a 2.4KW PV array above the roof. This array acts as a shade canopy at the roof stair access. The PV array was designed to provide 60-75% of the homes energy usage.
  • A copper roof acts as the "engine" that triggers a thermo-syphon, radiating heat from the sun into a ceiling plenum. The heated air begins to rise and is exhausted through "chimneys" on the building's north face. This hot, exhausting stream of air is continuously replenished with 100% fresh outside air that is routed across occupied space from a vented under-floor plenum.

Solio Solar Charger Review Comparison

This is a post that aggregates online reviews and comments about the Solio Solar Charger (shown in the picture to the right). I have been looking for a small solar charger device that I could use to charge my iPod or cell phone, and since the Solio kept popping up in my searches, I have decided to pull together reviews and comments from several websites. Thought I'd share what I have found ...

TreeHugger - 4 out of 5 Hugs - Comments:

  • It works
  • Took 7 hours of sunlight to charge an iPod
  • Simple to operate
  • Difficult to attach to a backpack during hikes
  • Difficult to position the charger perpendicular to sun’s rays

CNet - 8 out of 10 (Rated Excellent) - Comments:

  • Compact design
  • Does not balance on its side when open
  • Adapters fit most Motorola, Nokia & Samsung phones
  • Sony Ericssons are not supported
  • 8 – 10 hours of charge time required
  • Charging takes longer on cloudy days (Editor's note: duh!)
  • Suction cup included for attaching to a window

MyMac - 4 out of 5 - Comments:

  • 500 - 1000 charge cycles until you will need to replace the Solio internal battery
  • 2 flashes (of the Solio charge light) would charge a (iPod) mini and a 20GB, 4 flashes should charge a 40GB and 60GB iPods
  • Solio is weather resistant
  • Use a damp cloth to clean the Solio
  • The red “being charged” light goes away when the Solio is fully charged

Sustain Lane - 4 out of 5 - Comments:

  • I love telling people that I have a Solar-powered cell phone!
  • One of the best features is that it holds the charge so if you are off camping in the rain with no sun in sight, you can still use the solar powered Solio to charge your devices

Retailing for around $90, the Solio seems like a solid choice for the gadget-head with a conscience. You should also check out the comments at Amazon because there are some negative reviews posted there. I've come to take the Amazon user reviews with a grain of salt because it seems like people get really over-heated on that site.

If you have any experience with the Solio, please leave a comment right here.

How Green Is Your City?

Per Boston.com, there is a new book that ranks the 50 bigggest American cities in terms of "green-ness" ... also known as the amount of its electricity that is generated using renewable sources of power. Information about the book and - presumably - ways to purchase the book can be found at HowGreenIsYourCity.com.

Unfortunately, the full ranking of the cities does not seem to be available online. However, the Boston.com piece included a few nuggets:

Boston ranks high among US cities when it comes to using renewable energy, the only East Coast city to make the top 10, according to a new study. Oakland, Calif., topped the list, with 17 percent of its municipal electricity drawn from renewable energy sources. Boston ranked fourth on the list, with 8.6 percent of its electricity coming from renewable energy sources. Three California cities tied for second place on the list - Sacramento, San Francisco, and San Jose, which all got 12 percent of their municipal electricity from renewable sources. Other non-West Coast cities to make the top 10 list included Austin, Texas; Minneapolis; and Chicago.

Update: Renewable Energy Access provides more stats on the top 10; I updated the table below.

So the top 10 looks like:

  1. Oakland, CA - 17% renewable
  2. Sacramento/San Francisco/San Jose, CA - 12%
  3. Portland, OR - 10%
  4. Boston, MA - 8.6%
  5. San Diego, CA - 8%
  6. Austin, TX - 6%
  7. Los Angeles, CA - 5%
  8. Minneapolis, MN - 5%
  9. Seattle, WA - 3.5%
  10. Chicago, IL - 3%
  11. Source: SustainLane U.S. City Rankings data 2006/2007

Green Fantasyland: Denmark

There's a wonderful article from Outside Magazine that shows it is possible for industrialized nations to cut energy consumption, turn to renewable sources of energy, and prosper by doing it.

In fact, Samsø has spent the past decade becoming an eco-wonderland, setting up wind, solar, biofuels, and other renewable technologies to satisfy its energy needs. The island has even gone beyond "carbon neutrality," the cherished environmental goal of zeroing out the production of CO2, the greenhouse gas most responsible for global warming.

Samsø is an island in Denmark rich in the wind resource. They get so much wind that they can't use all of the electricity their turbines produce, so they sell the excess to the main electric grid. And even individuals are leveraging the wind.

Turbines are owned by private investors like Tranberg, by the government, or by cooperatives of people who bought shares to finance their construction. The process is democratic in the way so many things are in Denmark; shares cost about $360 each. Tranberg, for his part, took out a loan to buy his $1 million windmill six years ago, but the government guaranteed him an above-market price for his power. And the wind, which blows lustily here most days of the year, proved to be an even better friend than he and other islanders had hoped. Investors have seen returns of 8 percent or so a year, which works out to roughly $100,000 per onshore turbine. Tranberg's is already paid off. "It's enough income for me that I don't have to work, but I like to work," he says. Besides, he adds, talking tough for a man in clogs, "we can't put all that shit in the sky from coal. There's too much shit in the air."

The article has much, much more about this inspiring community that clearly "gets it". Check out the link to read the entire thing.

Solar Tour of Homes

Last weekend, my solar PV class toured 3 area homes that have active solar systems installed. Although it was about 10 degrees and snowing, the tour was really interesting. Our first stop was to a home in Troy, NY that uses a combination of active and passive solar energy.

Originally I planned to post some photos, but I found a video the owners posted. It's way more fun to watch solar junkies than read about them:

Sustainable Design for New Construction

Excellent tips from SolarWrights, a Rhode Island-based Solar Installation company, for anyone thinking about building sustainable and energy-efficient homes.

1. Site new homes so that you maximize the South wall. Minimize any roof protrusions such as pipes or dormers on the South roof to allow for the solar PV modules or solar thermal collectors. It is generally preferable to utilize a Gable roof design as opposed to a Hip roof.

2. Keep the heated area of the home under 3,000 sq. ft. Use isolated solar sunspaces attached to the south wall of the heated portion of the home. See below for more information on passive solar sunspaces. Use air-lock entries to minimize heat loss when entering and exiting the home. Attach the garage to the North side of the home to provide a buffer against the cold North winds in the winter.

3. Maximize the utilization of direct gain passive solar energy through South-facing windows and glass doors by using South-facing windows and doors that have a SHGC (Solar Heat Gain Coefficient) of at least .50. A typical window with Insulated, Low-E coating has a SHGC of .30 meaning that only 30% of the solar energy makes it into home. Use moveable window insulation to boost the insulation value at night.

4. Utilize isolated solar sunspaces to maximize passive solar energy during sunny periods and to reduce heat loss from the adjoining house walls during cloudy days and nights. (For more information, see below)

5. Utilize solar energy or geothermal heat for heating your home and hot water needs. For space heating, collectors need to be tilted at 60 degrees to maximize winter solar gain and minimize summer overheating. For solar hot water systems only, tilt the collectors at 45 degrees.

6. Utilize photovoltaics or wind turbines to generate clean electricity for your home's electric needs. For grid-connected photovoltaic systems, mount the array at around 35 degrees to maximize annual electric production.

7. Purchase energy star appliances and lights for your home. Never install recessed lights in cathedral ceilings.

8. Minimize heat loss from the building envelop by maximizing the insulation of foundation walls, outside walls and attics and cathedral ceilings. Consider pre-cast foundations or ICF foundations for maximum insulation. Consider using ICF's or SIPS for upper walls. Timber framed homes with Stress-skin panels are also an excellent way to build. Don't use unhealthy insulation such as fiberglass in your home; consider blown-in icynene or cellulose insulation.

9. Utilize green building materials in the construction of your home.

10. Landscape your property with plants and lawns that are drought resistant and don't require the use of dangerous pesticides or chemicals such as dandelion killers.

A Message From Bill Richardson: Conserve Energy

I don't know a whole lot about Bill Richardson other than the titles he has held, but I saw him interviewed today on This Week and I was stunned to hear him talking about the need for Americans to conserve energy. Video available at This Week's website - check it out for yourself.

While energy is certainly going to be a top issue in the 2008 election, this is the first time I have heard any of the candidates talking about reducing our use of energy. Since I see conservation as a critical component in any plan calling for transition away from fossil fuel energy, I welcome Richardson to the arena and I plan to find out more about his ideas. This guy might be the only candidate willing to face our energy reality ... interesting development in presidential politics.

Friday Jan 19th Links

If you are pro-renewable energy and anti-fossil fuel energy, you have to be encouraged by the Dems pushing through new legislation that repeals a corporate tax break for oil & gas companies instituted in 2004 and plans to allocate the projected tax revenues to renewable energy. Should be interesting to see if Bush vetos the bill.

Speaker Pelosi also announced a new House of Reps committee designed to look at the global warming and energy independence issues. As I wrote last week, this whole energy independence thing is a complete red herring. We're simply never going to run our transportation fleet the way we run it today on 100% domestic sources of gas or biofuel or anything else. If we changed the way we use the stuff, maybe one day we could seriously talk energy independence. Until then, this is headline news at its worst.

Speaking of global warming, some dude thinks it is a total hoax perpetrated by socialists in order to oppress developing nations. Wow! In his post, he shows a chart showing co2 concentration levels in the atmosphere over the past 400k years. He shows this chart to make the point that co2 levels are not currently out of the ordinary. Unfortunately, he is only showing us data through 1950. In fact, co2 concentration is out of control. According to this page, co2 concentration was around 375 parts per million in 2004 - well outside of the normal range. I think this is purely an effort at getting links to point into his site. Really sad to see someone willing to misrepresent the data in order to get a better Google ranking.

And finally, a story about a totally solar/hydrogen residence. Now that is energy independence, but it don't come cheap!

Same Old Song And Dance

It may be a new year on the calendar, but man, the story hasn't changed much, has it?

While the ethanol debate continues to unfold (and continues to look tragic), and supplies of crude oil keep falling (down 1.2% compared to same period last year - even in the absence of winter in most of the US), and Norway sets expectations for lower oil production (this is what depletion looks like, folks), and while we view images like the one below that shows an epic traffic jam in China ...

... the price of oil continues to oscillate like a Cuisinart and we read news that sales of hybrids are on the downslope.

Refreshing stuff, eh?

The energy complex appears to be floating aimlessly in no-man's land. Global warming appears to be settling in like a fat man at the all-you-can-eat buffet. The slow-motion energy crisis marches forward at the pace of a snail. Although I feel like I could have "skipped" 2006 and not missed much of anything, I can't wait to see what happens next week!

Might a Gas Shortage Be Around the Corner?

I know this is not the heavy driving season. I'm also aware that Americans seem to be cutting back on the number of miles they are driving. Both of which would seem to indicate a reduction in gasoline demand. At a time of lower demand, one would expect gasonline in storage to be on the higher side of average, correct?

Well, per the EIA, gasoline stocks are now pegged right at the bottom of the 5 year average range for this time of the year. Check out the graph:

The 5 year average range is represented by the thick blue band. At a time of the year when gas stocks should be growing, it looks like that is not happening in 2006. Why?

Lo and behold, demand is running high. Much higher than last year at this time, which appears to have taken a bite out of gas in storage:

Also, American gas imports have fallen significantly:

I'm going to bet that the reason Americans drove fewer miles in 2005 had more to do with massive hurricanes than anything else. Let's be honest, Americans are driving more than ever and consuming more gasoline than ever.

The gasoline supply chain is so huge that even at the bottom end of the 5 year range, the US currently has a 21 day supply of gas products in storage. Bottom line: no shortage around the corner ... but probably higher prices around the corner.

Energy Use Can Be Cut by Efficiency ... But It Won't Be

The NY Times tells us about a report to be released today by McKinsey Global Institute that concludes the following:

The growth rate of worldwide energy consumption could be cut by more than half over the next 15 years through more aggressive energy-efficiency efforts by households and industry

McKinsey claims that these cuts can be achieved through currently available technologies and require merely that "some product standards would have to be tightened and some policy incentives changed."

To their credit, McKinsey acknowledges that "many steps are not taken because energy users lack information or do not value efficiency enought to change their buying habits."

Somehow, that seems to be putting the matter a bit too lightly. In reality, "energy users" will not change unless they are forced to. That force will arrive in the form of reduced energy supply. I'm currently banging the shortage drumb because I'm convinced shortage is the only think that will dent our consumption and force us to change behavior when it comes to treatment of energy.

Until "energy users" comprehend that energy supply is scarce, they will not truly value energy. Until they truly value energy, they will squander it. That is the nature of the situation. However, it's great to know that once the shortage comes along, we'll be able to deal with it by reading the McKinsey report.

The Home as a System

I've been watching a new home go up just down the street. It's fascinating to watch the structure take shape ... from a rectangular hole in the mud to a neat looking 2 story plywood-sided house (they haven't quite finished building). I've always been interested in design and construction - I often wonder whether I should have pursued a career in architecture.

I'm also really excited by the notion that the choices builders make at time of planning and construction can impact energy consumption for years and years down the road. In a future where energy becomes more scarce and hence, more expensive, energy efficient home building is going to become very important.

The home is a system ... a group of interrelated elements that form a complex whole.

During the construction phase, if a home is not properly sealed and insulated that home will become more expensive to heat ... because heat will escape more easily than it might have. Every decision made during the design and build phase of home building will impact energy consumption and cost. Spending more to seal a house properly during construction will prove to be a very high ROI type decision for the owner down the road.

I hope one day to build my own energy efficient home. You can be damn sure it will be south-facing, air tight and renewable powered.

Top 10 Energy Don'ts

10. don't leave the tv on when you leave the house or go to a different room. i visited a friend's house this weekend. aside from the ridiculous fact that they have a tv in nearly every room, i kept finding various tvs left on - even when nobody was in the room.

9. don't go all high school and peel out when the light turns green. not only does it make you look like an a-hole, it's a waste of gas and tire rubber. relax a little behind the wheel

8. don't forget to draw your shades or blinds at home when it's really hot out. simply darkening the house can help keep the space cooler. that, in turn, will mean you need less a/c or whatever else you use to cool down.

7. don't underestimate the cooling power of some well placed fans. we've got a window unit a/c in our bedroom, but i think we've used it twice this summer. instead, we found that a box fan in the other window nearest the bed does a great job of keeping us cool. in fact, we usually wake at around 5am to turn it off, cause we're freezing our asses off by then.

6. don't drive when you can walk. pretty basic notion. go ahead, lace up the sneaks and smell the flowers. walking to the corner store or to a friend's place is really a nice change of pace. highly recommended.

5. don't neglect the little things on your car. inflate the tires to the proper pressure level. replace the air filter. these help conserve gas usage.

4. don't speed. i've been able to squeeze much much more out of my car this summer by driving around 60 mph on the highway. really, you need to experiment with lowering your speed. you will simply be amazed how much you can squeeze out of a full tank of gas at 60 mph.

3. don't leave electric appliances plugged in. if you have non-essential appliances plugged in but turned off, they could still be sucking down electricity. unplug the blender, toaster, microwave, etc when not in use

2. don't be caught unprepared for a power outage. buy some candles & make sure flashlights have fresh batteries. blackouts will become the norm in high demand seasons (summer especially)

1. don't forget conservation is something that can make a difference for your check book and for the world and it's one of the things you control. take back power!

It's Gonna Take Time

energy conservation takes will power and it's also not fun. saving energy is like cleaning your room. remember how eager you were to tackle that project? unless you drive a prius, there's really no direct, selfish benefit to conserving. even if you get a warm fuzzy because you drive a prius, i've been reading some stuff recently that indicates a backlash against prius drivers. at any rate, the initial hybrid buzz appears to be waning ... anyway, saving and conserving generally costs more of your time, your energy and your freedom.

and by freedom, i mean the type of freedom that allows you to go where you want, when you want. not the freedom protected in the constitution.

i've been driving 60 mph on the highway for the past month because i know that improves my gas mileage, which means i squeeze more out of every gallon i pump into the car. in this way, i can justify spending $3.09 per gallon. this is smart and it is the type of behavior the economists refer to when they talk about reduced demand caused by high price. true in my case.

but you know what? it's pretty boring to drive 60 and get passed by every car on the road. in some ways, it may not even be safe to drive 60 as a rule. i've had more than a few weird close calls on the road recently ... likely due to my lower speed, which is unexpected by other drivers who are making millions of calculations and estimates in their brains as they navigate the roadway.

driving slower is actually like work. i find it takes quite a lot of concentration to keep my speed pegged at 60 on roads i am conditioned to drive 70 or higher. i'm glad i have cruise control.

bottom line: driving slower is a good example of why conservation frowned upon by americans. it just doesn't feel right. it feels downright unnatural.

this movement is gonna take a lot of time. i'm trying to think of ways to make conservation fun this week.

It's Easy to Reduce Energy Costs at Home

Simple, smart ways to save energy at home:

1. Use compact flourescent lightbulbs (CFLs). CFLs use fewer watts than normal lightbulbs, so they use much less energy. As a result, they also last longer. CFLs cost a bit more than normal bulbs, but they are well worth the investment. In the long run, they use less energy and save you money.

2. Turn off the lights, the TV, the computer, etc. This is a no-brainer. If you're not in a room doing something, why is the light left on? It shouldn't be. Be conscious of energy waste.

3. Use the dishwasher less, use elbow grease more. Only use the dishwasher when it is absolutely full. If you have only a couple plates/glasses to clean, do them by hand in the sink. Try to eliminate use of the dishwasher for an entire month. Compare electric bill. You'll see what I mean.

4. If you must use A/C, set the temp higher or go to economy mode. A/Cs are huge energy sucks. Enough said.

5. Turn the temp up in your refrigerator. The refrigerator is typically the single biggest energy suck in your house. Other ways to save include locating the frig away from a heat source like an oven, make sure the door seals are airtight and open/close the door less.

These tips can really reduce your monthly electric bill. These are simple things, common sense things. They require only the smallest commitment to change.
