Wind generators’ cost declines reflect technology improvements and siting decisions
Between 2010 and 2016, the capacity-weighted average cost (real 2016$) of U.S. wind installations declined by one-third, from $2,361 per kilowatt (kW) to $1,587/kW, based on analysis in the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy’s…
Natural gas-fired electricity generation this summer expected to be near record high
EIA’s July 2018 Short-Term Energy Outlook (STEO) expects natural gas-fired power plants to supply 37% of U.S. electricity generation this summer (June, July, and August), near the record-high natural gas-fired generation share in summer 2016. EIA forecasts the share of…
China is a key destination for increasing U.S. energy exports
In recent years, as its domestic energy consumption has grown, China has become a more significant destination for U.S. energy exports. In particular, China has been among the largest importers of U.S. exports of crude oil, propane, and liquefied natural…
EIA adds Puerto Rico data to its U.S. power plant inventory

Petroleum, natural gas, and coal still dominate U.S. energy consumption
Fossil fuels—petroleum, natural gas, and coal—have accounted for at least 80% of energy consumption in the United States for well over a century. The fossil fuel share of total U.S. energy consumption in 2017 was the lowest share since 1902,…
Coal plant retirements and high summer electricity demand lower Texas reserve margin
The Electric Reliability Council of Texas (ERCOT), grid operator for most of the state of Texas, estimates a reserve margin of 11% for this summer—lower than previous years and ERCOT’s 13.75% reference reserve margin—indicating a smaller cushion of resources to…
