How many homes can 1 windmill power? At a 42% capacity factor (i.e., the average among recently built wind turbines in the United States, per the 2021 edition of the U.S. Department of Energy's Land-Based Wind Market Report), that average turbine would generate over 843,000 kWh per month—enough for more than 940 average U.S. homes. The amount of homes that can be powered by one windmill, also known as a wind turbine, can vary depending on several factors such as the size and capacity of the wind turbine, the average wind speed at the turbine site, and the energy consumption of the homes being powered. On average, a modern wind turbine with a capacity of 2 to 3 megawatts (MW) can generate enough electricity to power around 600 to 900 homes, assuming each home uses an average of 3 to 5 megawatt-hours (MWh) per year. However, it's important to note that wind power is an intermittent source of energy, meaning that the amount of electricity generated by a wind turbine can fluctuate depending on the wind conditions. Additionally, the electricity generated by a wind turbine may not directly power homes in the local area, as it can be fed into the grid and distributed to different locations.
