How many homes can an average wind turbine power? According to the U.S. Energy Information Administration, the average U.S. home uses 893 kilowatt-hours (kWh) of electricity per month. Per the U.S. Wind Turbine Database, the mean capacity of wind turbines that achieved commercial operations in 2020 is 2.75 megawatts (MW). 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. To put it another way, the average wind turbine that came online in 2020 generates enough electricity in just 46 minutes to power an average U.S. home for one month.
Powering England with the world’s largest offshore wind farm There are only seven offshore wind turbines off the coast of the United States compared to nearly 6,000 in Europe. This is the Hornsea Wind Farm, more than 300 turbines spread across 335 square miles generate enough electricity to help power more than 2 million homes a day. They’re nearly 600 feet high with spinning fiberglass blades roughly the length of the world’s largest passenger jet. Each blade weights almost 30 tons. This year 13% of Britain’s energy has come from offshore wind. “They are operating 98-99% of the time.”
Record energy haul: Offshore prototype operates over capacity for 24 hrs A prototype wind turbine has recorded an extraordinary single-day renewable energy production total, bringing in a massive 359 megawatt-hours in a 24-hour time period. Slated for serial production in 2024, the SG 14-222 DD uses three colossal 108-meter (354-ft) blades, creating a 39,000-sq-m (420,000-sq-ft) swept circle. And while it’s nominally rated at a 14 MW capacity, it offers a “power boost” function that can take energy production up to 15 MW.
