Editor's Note -- This page is currently being updated, but the current page does include previous studies regarding plug-in hybrids and electricity emissions.
I think plug-in hybrids are one of the best concepts floating around in the automotive world. Add some extra battery power to your Toyota Prius or Ford Escape hybrid, and a plug. Charge your batteries over night and most people can go to work and back without using hardly any gasoline.
Many have liked this idea, but questioned the gain in emissions since most electricity is made with coal.
Recent studies; however, by both the Electric Power Research Institute and the California Air Resources Board demonstrate that plug-in hybrids would drop total energy use per car by 45%, while reducing pollution and carbon dioxide emissions by 50% - after accounting for the additional electricity required to power the hybrid vehicles.
