S ustainable E nergy S cience and E ngineering C enter The reemergence of wind as a significant source of the world’s energy is the most significant development within the last few years. Wind turbine: a machine which converts the wind’s power into electricity. Windmill is a machine which converts the power in the wind into mechanical power. Wind Energy The giant 12 kW Brush Windmill in Cleveland, Ohio (~1900). Rotor diameter = 17 m Number of blades = 144 1930: 150 MW of installed capacity

S ustainable E nergy S cience and E ngineering C enter Poul La Cour (Denmark) was concerned with the storage of energy, and used the electricity from his wind turbines for electrolysis in order to produce hydrogen for the gas light in his school (~1900). One basic drawback of this scheme was the fact that he had to replace the windows of several school buildings several times, as the hydrogen exploded due to small amounts of oxygen in the hydrogen(!) This 3-bladed F.L.Smidth machine from 1942 looks more like the current machines, was a part of a wind-diesel system which ran the electricity supply on the island of Bogo in Denmark.

S ustainable E nergy S cience and E ngineering C enter Wind Energy Based on the U.S. average fuel mix, approximately 1.5 pounds of CO 2 is emitted for every kWh generated. A forest absorbs approximately 3 tons of CO 2 per acre of trees per year. A single 750-kilowatt (kW) wind turbine, produces roughly 2 million kilowatt-hours (kWh) of electricity annually. This means that an average wind turbine prevents the emission of 1500 tons of CO 2 each year. Thus, a single 750kW wind turbine prevents as much carbon dioxide from being emitted each year as could be absorbed by 500 acres of forest.
