Today, the entire coal industry—including mines and power plants—employs roughly 160,000 people. For scale, the solar industry provides 374,000 jobs in the US, with most of those people—261,000—working on solar at least half time. If you're a coal miner, or live in a mining community, the transition has been hard.
