Well, if the experience in Germany re solar cells is any indication of how the future might play out, there are several issues:

• global reliance on one market leads to supply bottlenecks and anti-competitive practices

• a loss of domestic industry leads to less overall innovation, a loss of high-paying jobs and a reduction in the diversity of the industrial base

• given the current American economy is tied to fossil fuel or adjacent industries, a failure to transition to clean industry may mean all those jobs, families, communities etc are at risk

• development of solar in China has led to a host of quality and environmental issues in manufacturing; reversing that trend is much harder now that it is entranced than it would have been to stop at the outset.
