  1. ECE 333 Green Electric Energy Lecture 19 Intro to Wind Energy Professor Tim O’Connell Department of Electrical andComputer Engineering

  2. Wind Power Systems

  3. Historical Development of Wind Power The first known wind turbine for producing electricity was by Charles F. Brush turbine, in Cleveland, Ohio in 1888 • 12 kW • (Illinois solar house in 2009 had roughly 9 kW) • Used electricity to charge batteries in the cellar of the owner’s mansion • Fun fact: Also the year Tesla invented the induction machine Note the person http://www.windpower.org/en/pictures/brush.htm

  4. Historical Development of Wind Power First wind turbine outside of the US to generate electricity was built by Poul la Cour in 1891 in Denmark • Used electricity from his wind turbines to electrolyze water to make hydrogen for the gas lights at the schoolhouse http://www.windpower.org/en/pictures/lacour.htm

  5. Historical Development of Wind Power In the US - first wind-electric systems built in the late 1890’s By 1930s and 1940s, hundreds of thousands were in use in rural areas not yet served by the grid Interest in wind power declined as the utility grid expanded and as reliable, inexpensive electricity could be purchased Oil crisis in 1970s created a renewed interest in wind until US government stopped giving tax credits Renewed interest again since the 1990s
