A Wind Turbine is A device that converts the kinetic energy of the wind into mechanical energy that can be used to drive equipment such as pumps. The addition of a generator allows the wind’s kinetic energy to be converted into electricity. There are two types of wind turbines, namely: horizontal axis turbines - blades rotate about a horizontal axis; and vertical axis turbines - blades rotate about a vertical axis.

The study showed that for a minimal cost, wind energy provides significant economic and environmental benefits. Wind turbines in Iowa reduced acid rain emissions by 2,500 tons, cut global warming pollutants by 650,000 tons, and provided 200 short-term and 40 long-term jobs.

wind turbines produce 3,285,000 kWh or 55,755,109,110 btu's of energy in a year, a 9,855 cubic meter lake, 684,375/2 tons of waste, 881,037/400 tons of co2, a 4,405,185/3,664 cubic meter container of oil, a 9,618,307,860 cubic meter lake from being polluted, 1,314 tons of coal, 657,000/7 metric tons of toxic lead, 657/1,600 tons of mercury a year, 7,929,333/2,960 tons of air pollution per year, 2,628/25 tons of fly ash, 4,433/400 metric tons of fossil fuels, 881,037/800 tons of biomass, 4,433/800 metric tons of carbon monoxide, 4,433/4,000 metric tons of nitrogen oxide, 97,893/160 tons of carbon, 75,361/80,000 metric tons of solid particles, 13,299/764 metric tons of ethanol, 10,950/13 metric tons of zinc, 4,023/4 tons of coke, 18,070,064/6,281 tons of ammonia, 22,322,585/7,607 tons of methanol, enough energy to power 1,724,625/2,887 homes, a CFL for 1,395/8 years, $394,200.00.

One turbine will save 18 tons of sulfur dioxide (the leading contributor to acid rain) and over 11/2 tons of nitrous oxides (a contributor to smog and regional haze), 9 tons of sulfur, 450,000 kwh of energy, a 1,350 cubic meter lake, over 12,069/7,328 tons of smog, 125,718,750/2,977 metric tons of global warming, 180 tons of coal, 150/13 metric tons of hydrogen, 22,500 metric tons of limestone, 120,690,000/23 cubic feet of natural gas, $54,000.00

a Wind turbine that is one foot tall could save almost 500/43 tons of air pollution

A 1 megawatt wind turbine will annually save 21,600 tons of co2 a year, 8,437,500 cubic meters of rain, 27,000 tons of air pollution per year, a 1,350,000 cubic meter lake, 1,350 tons of particulates each year, 27,104,000 decibels of sound intensity, 1,800 tons of ozone each year, 2,352,960,000 square meters of natural habitat potential, 7,058,880 metric tons of life, 1,838,250,000/253 tons of steam, 104,000/9 tons of dust each year, 490,200,000/23 tons of soda ash, 11,029,500/11 metric tons of coal, $54,000,000.00, gain almost 117,000 tons of oxygen per year,
