-"Motor Trend" (or a magazine of that ilk) ran a piece comparing a Leaf, with a Volt, with a Prius to compare both their relative efficiency AND "green-ness". It turns out there were dramatic differences depending on where you live. For instance, a Leaf makes most sense where I live because electricity is relatively inexpensive and most all of it comes from wind or hydro. But, the "story" changes dramatically if you live in a state with more expensive power made from coal.
lemme Guess.... you live in the north west...probably washington or oregon.
Your power won't be cheap much longer....subsidies will run away and the price of the megawatt will increase drastically when the coal grid shuts down. A megawatt is a meagwatt is a meagwatt and it is a commodity.
