For many remote communities, electrical power is provided by diesel generators. Wind power is a viable option to offset the cost of fuel. Wind Turbines are becoming more and more popular as the idea of “green energy” expands. Matt McCombs. History. The first wind turbines were created in 500 A.D. by the Persians. . The Persians used the idea of wind power for everyday work such as grain grinding and water pumping cutting down on manual labor.. Xavier, . Daoud. , . Yegor. , . Tassiann. WIND POWER VS. Other forms of renewable energy. Can produce efficient electricity anytime. All countries have naturally windy areas. Solar power costs nearly twice more KWh than wind power.
