In 2004, the Centralina region (the Greater Charlotte metro area, which straddles the North CarolinaSouth Carolina border) was designated as a non-attainment area for ozone under the Clean Air Act. But I predict that when this happens with hydrogen, hydrogen-powered vehicles will supplant the plug-in electrics.
Scientist have confirmed that unlike gasoline cars, plug-ins will get cleaner as they get older -- because our power grid is getting cleaner. The comparison keeps being raised, though studies are conclusive: The "well-to-wheel" emissions of electric vehicles are lower than those from gasoline internal combustion vehicles.
