Electricity generated from the wind replaces generation from conventional power stations, thus preventing the emissions of several greenhouse gases, including carbon and sulphur dioxides. Wind turbines in the UK currently prevent the emission of one and three-quarter million tonnes of carbon dioxide each year.
- Reduction of carbon dioxide emissions in order to slow climate change: Fossil fuels such as coal, gas and oil release carbon dioxide into the atmosphere, whereas wind energy produces no carbon dioxide.
- A desire for cleaner fuels: Traditional fossil fuels contribute to air pollution which can cause respiratory diseases, whereas wind energy is a clean fuel with no harmful by-products.
- Reduction of the country’s dependence on traditional energy sources: Traditional energy reserves, e.g. oil, gas and coal, are declining. Wind energy makes a country more self-sufficient, less reliant on energy imports and less vulnerable to security threats. Renewable energy sources add diversity to energy supplies, providing a more dependable energy resource.
- Wind is free and supplies are infinite: The wind is a huge resource which can easily be converted to electricity. Maximum electricity production from wind turbines occurs at times of peak electricity demand, e.g. cold, windy winter days.
- Value for Money: The cost of wind energy is now very price competitive compared with traditional energy sources
