Do wind turbines save energy?
On average it takes less than six months for a wind turbine to recover all of the energy required to build and operate it. Wind turbines use energy from the moving air to generate electricity. Therefore, a modern wind turbine will displace the emissions of other electricity sources such as coal-fired power stations. For example, a 1.5 megawatt (MW) turbine will annually displace 3,000 tons of carbon dioxide generated by traditional electricity sources.
