I saw a presentation on plug in electrics. According to presenter, the tail pipe emissions from a gas engine are as bad as the dirtiest, nastiest coal fire plant. So if the power used to charge the battery comes from renewables, nuke, or cleaner coal, you are better off with a plug in electric. Go ahead and call your power company and ask them exactly what plant your power comes from. I am sure the will be able to tell you right away.
No offense but your presented was either ignorant or lying. Current tail pipe emissions in the US are WAY cleaner than a traditional coal plant.
Renewal power plants? Where am I finding them? I love nukes but try finding a green advocate to back them.
