2nd Green Revolution - Part 60

GreenCars.org Releases 2011 Car Rankings

GreenCars.org, in conjunction with the American Council for an Energy-Efficient Economy, “an independent, nonprofit research group dedicated to advancing energy efficiency as a means of promoting economic prosperity, energy security, and environmental protection” released their 14th annual environmental ratings last Thursday. The rankings include plug-ins, gasoline hybrids, diesels, natural gas vehicles, and conventional gasoline vehicles. Despite the hype of the all-electric Nissan Leaf (review here), and the 2011 Car of the Year, Honda’s natural gas Civic GX won for the 8th consecutive year.

Here are the top rated vehicles:

Semi Trucks, Supercomputers, and Innovative Companies: A Powerful Triumvirate

The EnergyBlog run by the Department of Energy (DOE) is a great source for interesting, relevant, and often exciting news on – you guessed it – energy. Last week there was a little noticed announcement about a public-private-partnership (PPP) that is coming up with ways to make semi trucks 7-12% more efficient.

Sitting in Oak Ridge National Laboratory in Tennessee is one of the most powerful computers in the world. Dubbed Jaguar, the DOE’s machine has computational power 100,000 times greater than the typical laptop. The government is allowing innovative companies to use the computer “to develop and test new products that can be manufactured in the United States.

BMI corporation, a small outfit based in South Carolina and Georgia, has used Jaguar to create a component that can be attached to the undercarriage of a semi (photo below) to reduce wind resistance, thereby saving fuel and money. From the blog:

The result is a new product being manufactured in Georgia that will make semi trucks 7 to 12 percent more fuel efficient. The potential impact is huge – outfitting all of America’s 1.3 million class 8 semi trucks with this kind of technology would save about 1.5 billion gallons of diesel fuel each year, meaning a savings of about $5 billion a year. The company was able to use the supercomputer to dramatically reduce both the time and cost of moving from a concept to a specific design that was ready to be manufactured. Originally, the process was supposed to take 3 ½ years. With the partnership of the Department of Energy and the Jaguar supercomputer, they did it in 18 months.

Seemingly small innovations like this can have a large impact when spread across an entire industry. Such innovation happening across various industries can have a large impact on curtailing energy use and pollution across the world.
Too rosy a prognosis? Well, I guess you could say this one’s optimistic.

An Argument for Government Mandated Solar Power

Whenever I see a large, flat (or properly pitched) south facing roof I wonder why there isn’t a photovoltaic array or solar thermal system attached. Every weekend while walking to the market I pass a large post office facility with a flat roof and no trees to the south and no buildings blocking the sun. I realize that the cost of the materials and installation are high. However, if we are serious about energy independence and clean sources of electricity, then the government needs to lead. In addition, we need to implement energy conservation measures to start and address easy fixes like weatherization and efficiency. For individual homeowners, photovoltaic systems may be an economic hardship. For this reason, low interest loans (similar to student loans) should be made available to interested parties.

A less popular thought I’ve had is that all government structures with flat or south facing roofs should have photovoltaic arrays installed. Yes, more government spending is a touchy subject; it could have to be offset by cuts in other areas.  However, with a reasonable return on investment and monetary savings from reduced utility expenses, the public and both political parties should be amenable.

My Driving Impressions and Review of the Nissan Leaf: Ready for Prime Time?

The 2011 Nissan Leaf is the world’s first affordable, mass produced, all electric vehicle (EV). It comes with an 8 year/100k mile warranty for the batteries, gets a purported 100 mile range on a full charge, and costs only $2.75 to fill up during off-peak hours. Best of all, fully electric vehicles are eligible for thousands of dollars in tax credits. But, after learning more about the Leaf and taking it for a test drive during Nissan’s Drive Electric Tour, I was left with mixed feelings.

For those living in states offering rebates, the Leaf is a pretty good value (click here to see what your state offers). After the federal rebate of $7,500, states like California and Georgia cut another $5,000 from the Leaf’s $33,000 base price tag. With its price now around $22,000, I think the Leaf is a pretty good value, even if it is a few thousand away from a comparable gas-powered car. On top of this, the federal government also offers a tax credit of $1,000 for the 220V Aerovironment charging equipment (covering about half the cost). Some states even give EV owners additional perks like free parking, use of HOV lanes, and exemption from vehicle excise taxes.

Another appealing aspect of the Leaf is how it drives. As batteries provide maximum torque from a standstill, the Leaf (rated at 207 lb-ft) pulls smoothly from stop, and up to 50mph without much effort. Acceleration after this point begins to trail off, but never feels strained since the motor makes about the same noise as a golf cart. Compared to a Prius, the Leaf’s zero-to-sixty time of 10 seconds dead is 2.5 seconds faster. However, the Prius closes this gap to only 1 second in the quarter mile. The Leaf also felt surprisingly stable due to its low center of gravity (accomplished by placing the 600lbs of batteries under the floorboards). Though its sloppy cornering did not deliver on what Nissan’s marketing department calls “seriously fun handling,” the lower center of gravity definitely makes the car feel more upscale and planted.

Despite this, the Leaf is not for everyone. The most obvious reason for this is

Five Friday Facts: U.S. Waste and Recycling Statistics

The following facts come from the Environmental Protection Agency.

  • In 2009, Americans generated approximately 243 million tons of waste, which was dumped (54.3 percent), recycled (33.8 percent), or burned (11.9 percent).
  • The 2009 recycling efforts prevented approximately 178 million metric tons of carbon dioxide from being released. This is equivalent to the annual emissions of 33 million cars.
  • Paper and cardboard made up 28 percent of total waste in 2009 (before recycling).
  • In 1960, the average amount of waste per person was 2.7 pounds per day. Since peaking at 4.7 pounds per day in 2000, per capita waste has gradually decreased to 4.3 pounds in 2009.
  • The 2009 recycling rate of 33.8 percent was more than double the 1990 rate (16 percent), and more than five times the 1960 rate (6.4 percent).

    The Living Building Challenge

    Although it may not be part of the vernacular, LEED (Leadership for Energy and Environmental Design) certification has become more prevalent in the last few years. As awareness about the scarcity of resources has been brought to the attention of the general public, there is a need to renovate preexisting structures and design in addition to building new ones. These structures would be able to take advantage of energy efficiency and natural lighting among other eco-features that have become increasingly important.

    With an eye to the future and a regenerative economy, The Living Building Challenge (LBC) is

    Secretary Chu, the DOE, and the Future

    Appointing Steven Chu as Secretary of Energy was one of President Obama’s finest moves. Having a Secretary of Energy focused on energy sources other than fossil fuels is important. Chu gets a lot of flack from fossil fuel folks for not paying attention to “dinosaur” fuel, but the hydrocarbon industry has commanded the government’s attention for about the last 100 years, and they still get plenty of notice and support. But just about everybody knows we can’t stay on the stuff forever, whether you take the national security argument, the environmental angle, or a peak oil view. Having a Nobel prize winning physicist at the helm ensures that the Department start paying attention to the necessity of concentrating on renewable energy while putting the focus more on science and less on politics. The apparatus to deal with hydrocarbons is in place and can function fine without the topmost level of attention.

    We live in incredibly exciting times. We are witnessing

    Help the Environment: Donate Your Old Car

    This is a guest post by Giveacar.co.uk, a “social enterprise that raises money for charities by accepting donations of unwanted cars.”

    Car disposal can be a difficult task. If your car is old or faulty it might not sell easily which can lead to it sitting on your driveway for weeks or even months! In addition, old cars can be hideously polluting, not only in terms of exhaust emissions – though those are bad enough – but also because the brake fluid, battery acid, and oil all may start leaking, poisoning the local environment.

    With a lot of new cars greener than their predecessors, the benefits of replacing an old car with a new one get better, particularly with the cost of fuel rising like it is. A lot of money can be saved by driving a car with a higher MPG (Miles Per Gallon) rating. In addition,
