A great advantage of using wind energy is that, unlike power generation from combustion of fossil fuels, it produces no gas emissions/ Even a small 750 kW wind turbine operating with wind speeds just above that of a cut-off would reduce annual emissions to the atmosphere by 1200 t of carbon dioxide, 6.9 t of sulphur dioxide and 4.3 t of nitrogen dioxide, compared with the equivalent power output from coal-fired generators.

Wind energy is inexhaustible and free of fuel costs. Given advanced technology, wind energy could provide up to 20% of the energy needs of the United States. This is equivalent to the amount currently provided there by nuclear power.
