374,000 people are employed in solar energy. 187,000 people are employed in oil, gas, and coal power combined. The transfer is already happening. In fact, it is so far along at this point it can't be stopped. New solar power plants are undercutting new coal power plant construction costs. Coal, being the traditionally CHEAPEST power plant choice. There is no stopping this transfer no matter how much the GOP tries.
You should be asking yourself, "who exactly is making so much money off the current traditional system that they are doing everything they can to prevent an energy revolution?" THAT, is the real question.
