Is cooking with gas or electricity greener?

[fishmom]

I live in California, and I have always been told that cooking with natural gas was more efficient and better for the environment than using electricity. But now I have a community aggregator for my electric source, and I am purchasing what is supposed to be 100% renewable electricity. Of course, that electricity comes to me through the PG&E grid, so that adds another complication.


So my question is: if I can switch some of my cooking to electric appliances (fry pan,electric oven) am I moving in an environmentally-friendly direction? I have a gas range with a large oven, which I use for baking and braising, but I also have an electric wall oven, as well as a microwave.


I know there are some very savvy scientific thinkers here. Any advice?
