How is the electricity made? 80% of the US is fossil, NG, coal.
20% is renewable. Here on LI, I'd guess 100% fossil.

I think because it's a lot more efficient, even if it uses natural gas produced electric it would be better. But around here, it would be a lot better because we hardly use any dirty power (although hydro is very damaging to the environment in its own ways).
