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".
Solar power in the United States
A 1998 report by the United States Department of Energy found available domestic solar energy (including biomass) technically accessible regardless of cost amounted to 586,687 Quadrillion BTUs (Quads); 95% of this was biomass. 
Coal represented the second largest resource, a distant 38,147 Quads. 
Predictions of how much solar power was economically feasible to collect amounted to 352 quads, compared with 5,266 quads from coal. 
The assumptions used in the report were based on a predicted 2010 price of a barrel of oil being $38, and multiplied annual renewable resources by 30 for comparison with non-renewable resources. The total annual energy consumption of the United States in 2007 was approximately 100 Quads, less than 0.5% of what is theoretically available from sunlight.
