Wind Power Essay -- Wind Energy Global Warming

The force out of roll up wheel might is a free and limitless proponent source. No matter where you go, on that point will always be wind. In the past, wind was captured and controlled through the determination of sails for the advocateing of ships. Now that larger amounts of energy have been found, through the burning of fossil fuels, the art of sailing has faded to a recreational sport. Wind has as well been used in the past to power mills, which have been used to centre water and grind grains. Though now these techniques of harnessing winds power are now not widely used, even though it is an sound power source. Wind is created by the uneven heating of the earths surface, and therefore, is an unlimited source. The problem with fossil fuels is that they are pollutant and will eventually hasten out, whereas wind is clean and abundant. The technology and efficiency of windmills has improved significantly over the numerous years that they have been around.Figure 1 Windmills of the Past, Figure 2 and Present(University at Buffalo)The Power of Wind 3Figure 3 Mills and the Power Generated(University at Buffalo)The windmill is a large vertical structure that can stand up to 500 tall with blades as large as 250. As the wind passes the rotor blades, the blades are laboured to spin, therefore rotating the main shaft. Now, do to modern computers, windmills have been able to utilize a gearbox, improving the effectiveness of wind energy. These gears will control how steady the high-speed shaft will spin, the faster it spins in the generator, the more power that is produced. Then, the power is transported down the tower and directly into the city grid system.The Power of Wind 4Figure 4 Structure of a Wind Turbine (University at Buffalo)Advantages and Dis... ... (The Economist, July 26, 2007)Wind in the FutureWind energy is unquestionably going to be a valuable resource in the future. The unseasoned York State Energy Research and Development Authority has a replenishment Portfolio Standard which requires that 25% of our electricity be produced from renewable sources by 2013. This shows that the US is already converting to renewable resources such as wind and solar.The Power of Wind 6ReferencesUniversity at Buffalo, UB Green Wind Energy.
