Electric Cars Dirtier Than Conventional Fuel Cars

In a recent IEEE Spectrum story titled, "Unclean at Any Speed," Ozzie Zehner contends based on research that electric cars don't solve the automobile's environmental problems. After factoring in the big picture from beginning to end of production of the vehicle, its battery pack, and the charger, the inefficiencies of electric power production and distribution, and battery change-out and disposal, even reaching break-even is questionable. Mr. Zehner, BTW, is a convert from the EV church of true believers, having even built his own e-car decades ago when doing so would more likely elicit strange looks than entranced gazes of fawning approval. He changed sides after extensive research suggested maybe the numbers were being manipulated in order to advance an agenda. The impetus to "go green" with autos has more to do with a need to feel good about one's self than reality. That said, I'd gratefully accept a donation of a Tesla Roadster any day.
