Chinese ripped off U.S.-based solar, went crazy, drove margins to 0%, overproduced, dumped in U.S., reduced U.S. profit incentive in solar development, and are now going to restrict supply to try to get prices up.

Meantime, we've had less serious R&D investment in solar than we would have had otherwise.

So, no, globalization doesn't always work especially when one of the other majors is a state-directed Communist country.
