@evan Bounced between qualified yes and qualified no because the answer depends on whether "powered by" is interpreted as "completely powered by". I feel like in this context "partially" is a useful answer
In my case: a nontrivial part of NJ's power mix seems to come from nuclear, though it's still majority gas-powered. Plan to look into ways of improving this for my own usage soon but I've only just moved so don't know the local options here yet
