Wind energy is the use of our natural wind converting it into mechanical energy which ultimately becomes electricity. You may not realize it, but we've been using wind energy that dates back centuries. It pumped water, milled grain and many other things. (Resources, awea.org) For as long as recorded history, people have had the ability to use wind as a source of energy. Wind power was used to push boats along rivers as early as 5000 BC. By 200 BC, China used windmills to pump water, while Persia and the Middle East used vertical-axis windmills with woven reed sails to grind grain. (wind-energy-history, energy.gov) Eventually, wind energy discoveries became vast. Plethora of ideas developed. During the 11th century, people in the Middle East used windmills for food production. This then allowed nomads, merchants and crusaders to bring the idea further back to Europe. The Dutch further improved the windmill by making it for the drainage of lakes and swamps into rivers. Colonists brought this advanced technology to the New World and began using windmills to pump water for farms, ranches, and more. Then, eventually, to generate electricity, for homes and industries and which will soon become wind turbines. To calculate such wind turbines, it depends on three main variables: the size of the turbine, the wind speed and the efficiency of the turbine and the generator. The formula to calculate wind power is: P=½ρAV³.P = power in watts. ρ = The density of the air (1.2 kg/m³ at sea level and 20° C) A = The area swept by the turbine blades (m² square meters) V = Wind speed (metres per second) (Kit and wind turbine supplies, windgenkits)Let's try this equation. Let's say we have a nice... middle of paper......rgy. Texas ranks first in the state for the most MW (megawatts) installed, with more than 7,772 turbines alone. Did you know that China has the largest wind market of any country? It ranked 1 among all countries. China has about 67.7 gigawatts of wind capacity from its massive facilities. The United States was behind China, ranking 2nd for having a total wind energy capacity of 60 gigawatts. Did you also know that wind energy is actually solar energy? Crazy right? The sun is also responsible for what we call “wind energy”. (10 Amazing Facts About Wind Energy, science.howstuffworks.com) Do you expect these giant turbines to make loud noises? Well, it's totally the opposite. It's actually surprisingly quiet. Noise impacts are regulated by municipalities and the Massachusetts Department of Environmental Protection (MassDEP).
