petroleum is not a significant fraction of energy on the power grid.

It looks like about 1/3 to me. I would say that is significant. I wonder if the study would have the same conclusion now that oil costs about 1/2 of what it did several months ago.

Natural Gas != Oil. These products might come out of the same well but do not track prices.

All oil based products are less than 1%. Nat Gas is 27%, Coal 39%.
