Are Electric Vehicles an Eco-friendly Replacement for Internal Combustion Engines?
Glenn Doty is a vital part of Doty Windfuels, a company with a terrific future in synthetic fuels made from off-peak wind energy, water, and CO2. Of course, their industry position makes Glenn and his company a natural competitor to electric vehicles, and thus some may regard the statements he makes on the subject as suspect. Still, as a scientist, I’ve consistently seen that he maintains a total objectivity in his analysis. In his recent comment, he’s brought up some nteresting and important fallacies in the analyses we’ve used in determining the validity of electric transportation as an eco-friendly replacement for internal combustion engines. Having said this, here are a few things to think about.
1) A significant amount of electrical energy from coal is dumped back to ground each night because the rapid ramping of coal plants is not feasible and the off-peak energy is too expensive to store. To that degree, of course, one could say that any of the energy that would go to charging EVs in that scenario would have no carbon content at all.
2) Some of the most EV-friendly parts of the world, e.g., the Pacific Northwest of the US with its massive amounts of hydro, and France with its nuclear, produce electricity 24 hours a day with very little carbon.
