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. Natural gas. from coal.

Energy Vault to provide 1.6 GWh of gravity energy storage to support DG Fuels SAF projects

Green Car Congress

This initial project will be followed by additional projects in British Columbia and Ohio. The system uses proprietary technology to autonomously orchestrate the lifting and lowering of the bricks, storing the potential energy in the elevation gain, and generating then discharging electricity as the bricks are lowered.

Ohio bill would grant permanent subsidies to coal-fired power plants

Green Car Reports

It's now widely acknowledged that the energy and electricity-generation landscape is changing rapidly. has vastly increased its oil and gas production, driving down prices of fossil fuels globally. At the same time, ever-cheaper renewable energy—not only solar, but surprisingly fast-growing wind generation—is now.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. The question of electricity costs vs. health and environmental cost is important to ask everywhere, Michalek said. Credit: ACS, Weis et al.
