Wind power in the United States
The 2011 NREL report, "Large-Scale Offshore Wind Power in the United States", analyzes the current state of the offshore wind energy industry. According to the report, offshore wind resource development would help the country to achieve 20% of its electric power from wind by 2030 and to revitalize the manufacturing sector. Offshore wind could supply 54 gigawatts of capacity to the nation's electrical grid, thereby increasing energy security. It could also generate an estimated $200 billion in new economic activity and create thousands of permanent jobs. NREL’s report concludes that "the development of the nation’s offshore wind resources can provide many potential benefits, and that offshore wind energy could play a vital role in future U.S. energy markets".
Natural gas in the United States
In the decade 2005 to 2015, electricity generated by natural gas increased by 574 billion kilowatt-hours, more than triple the increase of the second-fastest-growing source, wind energy, which increased 173 billion kilowatt-hours over the same period. Natural gas-generated electricity increased its share of total US electricity from 18.8 percent in 2005, to 32.6 percent in 2015. The increase in gas-generated electricity was mostly at the expense of coal power, which fell from 49.6 percent of US electricity in 2005, to 33.2 percent in 2015. Natural gas surpassed coal as the number one generator of US electricity in late 2015. During the 12-month period through August 2016, natural gas generated 34.5 percent of US electricity, versus 29.8 percent for coal.
