I'm currently reading Griffith's Classical Electrodynamics and Jackson's Electrodynamics, coupled with lecture notes on plasma physics, in order to take a crack at the problem of nuclear fusion. Many other people are doing similar things, because it may possibly be the most important invention that anyone will ever create.
Oh, I don't mean that we should ignore fusion. We should invest in its research, probably as much as is helpful to speed it up. But when considering how to reduce greenhouse emissions right now, fusion is not an option.
