Study shows bamboo ethanol in China technically and economically feasible, cost-competitive with gasoline

Green Car Congress

Now, researchers at Imperial College London have shown that bioethanol production from bamboo in China is both technically and economically feasible, as well as cost-competitive with gasoline. China bioethanol pump price for five enzyme loading scenarios in ( a ) 2011 with a 16¢ per liter (60.6¢ Click to enlarge.

Congressional Budget Office estimates US federal policies promoting EVs and other fuel-efficient vehicles will cost $7.5B through 2019; little or no impact on gasoline use and GHG in the short term

Green Car Congress

Tax credits and gasoline prices necessary for various electric vehicles to be cost-competitive with conventional vehicles at 2011 vehicle prices. Those people who purchase electric vehicles because of the tax credit use less gasoline and produce fewer emissions of greenhouse gases than would otherwise be the case.

Perspective: Drive Star Conversion Program Could Cut US Oil Use in Half by 2020

Green Car Congress

We’re about to enact the “Home Star” and “Building Star” programs—putting people to work on “Cash for Caulkers” retrofits that will make buildings more comfortable and cut owners’ fuel costs. Cash for Conversions” will start by fixing many of our 100 million trucks, vans, and buses. They now gulp down one third of the oil we use.

CMU study finds that HEVs and PHEVs with small battery packs offer more emissions and oil displacement benefits per dollar spent than large pack PHEVs and BEVs; policy implications

Green Car Congress

Although gasoline production and combustion produce significant emissions, battery and electricity production emissions. Under an optimistic scenario, plug-in vehicles with large battery packs could offer lower damage at lower lifetime cost, the researchers found. Michalek et al. are also substantial. —Michalek et al.

Separate MIT, IEA reports both outline major expansion in role of natural gas; caution on climate benefits

Green Car Congress

The new report, part of the World Energy Outlook (WEO) 2011 series, examines the key factors that could result in a more prominent role for natural gas in the global energy mix, and the implications for other fuels, energy security and climate change. It is clean and flexible.
