Wind Energy Technologies
The U.S. Department of Energy defines the scale of wind turbine technologies as follows: utility-scale is greater than 1 megawatt (MW) in size, mid-size turbines are 101 kilowatts (kW) to 1 MW in size, and small turbines are up to 100 kW in size. Distributed wind systems are defined as systems connected on the customer side of the meter (to meet the onsite load) or directly to the local grid (to support grid operations or offset large loads nearby). Community wind is characterized by local ownership and control and includes many distributed wind projects. Offshore wind projects, of course, capture the winds off the coasts and convert them to electricity. Learn more about the technology classes at the links below.

Equation for Wind Power
- Wind speed
- The amount of energy in the wind varies with the cube of the wind speed; in other words, if the wind speed doubles, there is eight times more energy in the wind (). Small changes in wind speed have a large impact on the amount of power available in the wind.
- Air density
- The more dense the air, the more energy received by the turbine. Air density varies with elevation and temperature. Air is less dense at higher elevations than at sea level, and warm air is less dense than cold air. All else being equal, turbines will produce more power at lower elevations and in locations with cooler average temperatures.
- Swept area of the turbine
- The larger the swept area (the size of the area through which the rotor spins), the more power the turbine can capture from the wind. Since swept area is , where r = radius of the rotor, a small increase in blade length results in a larger increase in the power available to the turbine.
Wind Decision Support Tools
- Wind Atlas Analysis and Application Program (WAsP) is a PC program for predicting wind resources and power productions from wind turbines and farms.
