VW’s Jetta BlueTDI: 60 MPG, 90% Emissions Reduction for NOx. VW’s ultra-low emission Jetta BlueTDI will be coming to the US mid-summer, according to an announcement made late last month at the Vienna Motor Symposium.This newer version of the Jetta will meet the strictest emissions standards in the world.

Not all biofuels are created equal, as the chart above illustrates (click the image to see full size). It’s one of the best depictions I’ve seen of how each biofuel feedstock has completely different impacts on overall greenhouse gas emissions, water and pesticide use, and the energy required to produce the fuel.

Homemade ethanol guru Floyd S. Butterfield and Silicon Valley entrepreneur and innovator Thomas J. Quinn want to see you making ethanol in your backyard. Their creation, called the E-Fuel 100 MicroFueler, is a stacked washer-dryer sized reactor that can convert sugar into ethanol for (they claim) $1.00 per gallon.

300 garbage collection trucks in California will soon be fueled by the same trash that they haul. Landfill gas will be purified and liquefied, producing up to 13,000 gallons of liquefied natural gas (LNG) daily.

Senator Grassley rebuts the argument that ethanol and corn farmers are to blame for rising food prices. He says increased oil prices play a role.

Small cars like these have scored big among buyers looking for a way to control rising gas prices; over the last year, the average cost of a gallon has risen more than 60 cents.

General Motors announced today it would be entering into a strategic relationship with Mascoma Corp., a second-generation biofuel company with the technology to produce cellulosic ethanol from non-food sources via a single-step biochemical conversion. This is GM’s second investment in a cellulosic ethanol company, after announcing partnership with Coskata back in January.

Ever feel like taking your bicycle out for a spin, but don’t know where you will stow your cargo. It’s easy to understand how an errand like grocery shopping could warrant the use of a car; where would you stash all of your goods on a bike?

This morning on NPR, President Bush tried to blame congress for the nation’s high gas, food, and electricity prices. Apparently, Congress has been thwarting the President’s attempts to fix the economy: “I’ve repeatedly submitted proposals to help address these problems,” the president said. “Yet time after time, Congress chose to block them.” His answer: Drill in ANWR.

While the national average price of gasoline is now $3.60, some residents of Utah are happily filling up on compressed natural gas (CNG) at $0.63 per gallon. That’s the country’s lowest price for CNG, which has understandably caused a surge in demand for vehicles running on a fuel that one man described as “practically free.”

Just because the new proposed rule on fuel economy is better than expected from the Bush administration, don’t start dancing in the streets just yet.

The White House has outlined their plan to increase fuel efficiency standards to 35 MPG by 2020, a move that will save Americans an estimated $100 billion in fuel costs. The proposal gives a boost to the timeline by requiring the mileage of passenger vehicles to average 31.6 MPG by 2015. That’s up from today’s average of 25 MPG.

Today is Earth Day, and it’s a great day to remind ourselves why we’re interested in things like renewable fuels and green car technology. It’s also a day to think about the role each of us plays in local and international environmental issues, from air pollution to the increasing cost of food.

Residents of Washington, Oregon, and Idaho are outpacing the national average decline in gas consumption, according to a new report by the Sightline Instutute.In the last 8 years, residents of these states have cut back by about a gallon per week, for a total gas consumption reduction of 11%. In the Pacific Northwest, gas usage has fallen to its lowest level since 1966, while CO2 emissions from gasoline have fallen by six-tenths of a ton per capita since 1999.
