Proposal: Solar Energy Science and Economy
The Economics public beta site and the launched Physics site are the two closest StackExchange sub-sites among all those in proposal, beta, and launched states. There are more Solar Energy Science and Economy related questions in those locations than anywhere else, and some of the example questions on Solar Energy Science and Economy already could conceivably be placed one one of those two sites as well.
We think they are a better fit here, but we could be wrong. Any thoughts?
