Explain the historical use of wind power in human civilizations.
Explain the historical use of wind power in human civilizations.
Human civilizations have harnessed wind power for thousands of years, using early forms of windmills to crush grain or pump water.
What are some key features of modern wind turbines?
What are some key features of modern wind turbines?
Modern wind turbines are much more complicated machines than traditional prairie windmills, with as many as 8,000 different components. They also have large blades averaging 210 feet in length and towers averaging over 320 feet tall, with an average capacity of 3.2 megawatts.
How do higher wind speeds impact electricity generation from wind turbines?
How do higher wind speeds impact electricity generation from wind turbines?
Higher wind speeds result in more electricity generation, leading to the construction of taller wind turbines to reach higher, windier areas above ground level.

Study Notes
Wind Energy in the United States
- The wind industry employs over 125,000 people, with 23,543 in manufacturing and 45,088 in construction.
- The U.S. has installed over 144,000 megawatts of wind capacity, with over 8,500 MW added in 2022, representing $12 billion in investment.
- Wind energy prices for power contracts signed in recent years range from 1.5–4 cents per kilowatt-hour.
- Wind energy supplies more than 10% of total U.S. electricity generation, with over 20% in 12 states and more than 50% in Iowa and South Dakota.
- Offshore wind has the potential to provide power to highly populated coastal cities, and the U.S. has small and large offshore wind projects in progress.
- U.S. offshore wind resources are abundant, with a technical resource potential of over 4,200 gigawatts of capacity.
- Offshore wind turbines can be extremely tall, with blades the length of a football field.
- Deploying 30 GW of offshore wind will require over 2,000 wind turbines and foundations, 6,800 miles of cable, and specialized vessels.
- The U.S. Department of Energy collaborates with industry and academia to address research challenges unique to U.S. offshore wind.
- U.S. offshore wind projects use undersea cables to transmit electricity to the grid, prioritizing where the electricity should go and distributing it into the electrical grid.
- The bulk of the nation's offshore wind resources are in deep waters, with about two-thirds in areas where conventional foundations are not practical.
- Nearly 80% of the nation’s electricity demand occurs in the coastal and Great Lakes states, where most Americans live, and offshore wind resources are conveniently located near these populations.
