> Electric Cars Are Cleaner Even When Powered by Coal
> Emissions from EVs 40% lower than gasoline cars, BNEF says
Researcher expects difference to grow as clean energy expands
> That’s the conclusion of research by BloombergNEF, which found carbon dioxide emissions from battery-powered vehicles were about 40 percent lower than for internal combustion engines last year.
"an average ICE vehicle will emit around 69 metric tonnes in its lifetime.
But an EV, in a state like Wyoming which is almost completely powered by coal, will only produce 66 metric tonnes if the vehicle is made by a manufacturer using a grid that is 13% renewables (the US national average)."
My back-of-the-envelope maths shows that fuelling an EV from a coal power source results in about the same thermal efficiency, and thus about the same CO2 emissions, as a modern diesel. Those published numbers show the same thing. I thought saving the planet required truly drastic reductions in CO2 output?
