Homework Help: A basic wind power question

  1. Dec 9, 2012 #1
    Hi, Why is hight of a wind generators tower so important? Given a 50-meter tower, at what wind 'power class' and at what 'power level' will wind power be considered economical (circa 2005)?

    Wind speed (usually) increases with height, and more height allows bigger rotors as well.

    Google "Wind Power"

    If you look at the velocity profile of a fluid moving across a flat horizontal plate you will see why elevation above the surface is important.

    Thank you both very much-

    Any ideas on if given a 50-meter tower, at what wind power 'class' and at what 'power level' will wind power be considered economical (in or about the yr 2005)? Best wishes,

    Was any turbine "economical" in 2005? Even today many need subsidies.
