Electric vs. Gasoline Cars: Uncovering the Real Climate Savior

The Truth About Cars

For instance, electricity generated from coal or natural gas is associated with higher carbon emissions, while renewable sources like wind or solar energy contribute negligible carbon pollution. As more renewable energy sources are integrated into the power grid, the overall greenhouse gas emissions associated with EVs can be further reduced.

Are EVs Charged Mostly By Coal Power in the US?

EV Adoption

Last year I wrote an article — Electric Vehicles Have Lower Well-to-Wheel Emissions in All 50 States and DC Than Gas-Powered Vehicles — looking at “well to wheel” from the US Department of Energy and my own analysis of EV sales and source of electricity by state. Said another way, residents of California purchased 390.9

NREL and partners to investigate secondary uses for electric drive vehicle batteries

Green Car Congress

The cost of Li-ion batteries currently affects the affordability of plug-in hybrid and electric vehicles (PHEV/EV) for consumers. While these PHEV/EV batteries degraded to 70%-80% of their original power/capacity are insufficient for automotive use, these aged batteries may still be useful and could be reused in other applications.
