The Pursuit of New Ways
to Boost Solar Development
The solar power boom in Germany, Spain, and parts of the United States has been fueled by government subsidies. But now some U.S. states — led by New Jersey, of all places — are pioneering a different approach: issuing tradable credits that can be sold on the open market. So far, the results have been promising.
