Assuming forecasts are correct, solar photovoltaics will be among the cheapest sources of energy. With declining prices, the U.S. Department of Energy projects solar power to account for 40% of U.S. electricity by 2035 and 45% by 2050. This would require producing 1600 gigawatts with solar technology.
