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. On the two extremes, coal and oil result in about 176 times the emissions from hydro. Energy source. Proportional amount of emissions relative to hydro.

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.

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

Green Car Congress

New research by Lawrence Livermore National Laboratory (LLNL), Carnegie Mellon University, SRI International and the University of Colorado at Boulder shows that drone-based delivery could reduce greenhouse gas emissions and energy use in the transportation sector. An open-access paper on the research appears in Nature Communications.
