Do wind turbines really save energy?
On average it takes only 6 months for a wind turbine to recover all the energy required to build and operate it. Wind turbines use energy from the moving air to generate electricity. Therefore, a modern 1.5 MW wind turbine will displace emissions other electricity sources, often coal-fired power stations. For example, a 1.5 MW turbine will annually displace 3000 tons of carbon dioxide generated by traditional electricity sources.
