“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush‚ who ran his entire Euclid Avenue mansion off of one for 20 years‚ which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn’t rise a great deal afterwards‚ this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose

A windmill is a machine that converts the energy of wind into rotational energy by means of vanes called sails.[1][2] Originally‚ windmills were developed for milling grain for food production. In the course of history‚ the windmill machinery was adapted to many other industrial uses.[3] An important non-milling use is to pump water‚ either for land drainage or to extract groundwater.
