As states continue to use less coal for electricity, driving electric vehicles becomes even cleaner

Green Car Congress

Battery electric vehicles are only as clean as the energy source used to generate the electricity that powers them. These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions. Energy source. Natural gas. Geothermal.

Brookhaven researchers improve understanding of how plants regulate oil synthesis; potential for more abundant bio-fuels and -products

Green Car Congress

Researchers at the US Department of Energy’s Brookhaven National Laboratory have discovered new details about biomolecules that retard oil production in plants. The biomolecule central to this study is the enzyme Acetyl-CoA carboxylase (ACCase), which determines the rate of oil production. —John Shanklin.

Study finds drone-based delivery could reduce GHG emissions and energy use in the transportation sector, if deployed sensibly

Green Car Congress

The range of regional greenhouse gas (GHG) intensities of electricity in the US is represented by comparing results from low-carbon California to relatively high-carbon Missouri. The technique accounts for upstream impacts, such as emissions from manufacturing the batteries or refining oil into diesel fuel.
