For all the talk about green-job creation, there’s an unavoidable problem with renewable-energy technologies and the policies that promote them: From an economic standpoint, they’re big losers,” said Max Schulz, an analyst at the Manhattan Institute, a free-market think tank.

“Renewables can’t produce the large volumes of useful, reliable energy that our economy needs at attractive prices. Government subsidizes renewables because — all things being equal — the free market won’t,” he said.
