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.
Listed are wind farms with a generating capacity of at least 150 megawatts (MW) or any of the three largest farms in its state with a generating capacity of at least 120 MW.

The 2010 edition of the Florida Building Code introduced significant changes to wind load design, in particular the presentation of the wind speed maps. [4] The Miami-Dade and Broward County norms, are both included in the High-Velocity Hurricane Zones (HVHZ) and contain more stringent requirements. [4]
In addition to the megawatt wind farms, community scale single wind turbines of from 250 kW to 750 kW are typically 50 meters high, and residential or farm wind turbines are typically 15–40 m (49–131 ft) high. To address these markets, maps are available showing wind potential at 30 m (98 ft) [7] and 50 m (160 ft). [8]
However, very high tip speeds also increase the drag on the blades, decreasing power production. Balancing these factors is what leads to most modern horizontal-axis wind turbines running at a tip speed ratio around 9. In addition, wind turbines usually limit the tip speed to around 80-90m/s due to leading edge erosion and high noise levels.
In 2023, 421.1 terawatt-hours were generated by wind power, or 10.07% of electricity in the United States. [4] The average wind turbine generates enough electricity in 46 minutes to power the average American home for one month. [5] In 2019, wind power surpassed hydroelectric power as the largest renewable energy source in the U.S.
