Although the current low price of natural gas threatens the economic rationale for renewable energy, a new report from the Solar Energy Industries Association (SEIA) and GTM Research says that the price of solar panels plummeted by more than 50% in 2010, and estimates that solar power will account for 10% of U.S. electricity by 2020, up from 1% currently. Meanwhile, American Wind Energy Association announced that wind power increased 31% last year, USA Today reports. As government subsidy programs for renewable energy expire, both the wind and solar industries will face "considerable consolidation," the article said.
