Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Once built, these turbines create no climate-warming greenhouse gas emissions, making this a “carbon-free” energy source that can provide electricity. Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. Wind is considered an alternative or renewable energy. Can wind farms really produce enough power to replace fossil fuels? The UK government's British energy security strategy sets ambitions for 50GW of offshore wind power generation – enough energy to power every home in the country – by 2030. As of 2024, hundreds of thousands of large turbines, in installations known as wind farms, were generating over 1,136 gigawatts of power, with 117 GW added each year.
