I live in Texas and pay a half-cent premium to get 100% wind-power at around 9.6c per kWh to charge my Nissan Leaf. Since I use a 7kw charger at home almost exclusively then actually running the car (not including it's production) is actually extremely "green". The owner friendly side of the deal is that I never visit gas stations, never change oil or other fluids, don't have to do anything much to it outside of tire rotation. Maintenance is both very cheap and very convenient (since there isn't much of it).
