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. The calculated relative amounts of well-to-wheels emissions of greenhouse gases from eight different energy sources are shown in the table below. Energy source. by Michael Sivak, Sivak Applied Research. from coal.

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. These warehouses, in turn, would take energy to run.
