Natural Gas and Renewables drive new electricity capacity

Source: U.S. Energy Information Administration, Form EIA-860 "Annual Electric Generator Report" and Form EIA-860M "Monthly Update to the Annual Electric Generator Report." 
Note: 2011 and 2012 data are preliminary. Data include all generators at plants >1MW in capacity, from the electric power, commercial, and industrial sectors. 

Most of the new generators built over the past 15 years are powered by natural gas or wind. In 2012, the addition of natural gas and renewable generators comes at a time when natural gas and renewable generation are contributing increasing amounts to total generation across much of the United States. In particular, efficient combined-cycle natural gas generators are competitive with coal generators over a large swath of the country.
