Hmm … based on this, we're going to go ahead and say that if you want a green state, the best possible location is the middle of the alphabet.

Beyond that, any surprises here? Vermont has "green" right in the name (albeit in French), so that hardly seems fair. But Nevada? If you're going to have one city built on the concept of spectacular waste, I guess it really helps to have low population density outside of that.
