Solar and Wind on Track to Dominate New U.S. Power Capacity in 2015

U.S. electric companies expect to install more than 20 gigawatts (GW) of utility-scale generating capacity this year and

Power generating capacity set to come online in 2015.
60 percent of that will be wind and solar power, according to a U.S. Energy Information Administration analysis. Energy companies plan to retire 16 GW of generating capacity this year, EIA numbers show, and 81 percent of that will be coal-fired power plants. The large number of coal plant retirements can be attributed to the EPA’s Mercury and Air Toxics Standards, which are slated to go into effect this year. Many companies decided that shuttering coal generators would be more cost effective than retrofitting them to meet the new standards, the EIA said. Natural gas power plants — which, although they burn fossil fuels, emit significantly less carbon than coal-fired plants — will make up roughly 32 percent of the additional capacity.
