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".
Wind power in the United States
Later, in the 1980s, California provided tax rebates for wind power. These rebates funded the first major use of wind power for utility electric power. These machines, gathered in large wind parks such as at Altamont Pass would be considered small and un-economic by modern wind power development standards. In 1985 half of the world's wind energy was generated at Altamont Pass. By the end of 1986 about 6,700 wind turbines, mostly less than 100 kW, had been installed at Altamont, at a cost of about $1 billion, and generated about 550 million kWh/year.
