Wind Energy“Take care, Excellency; those things over there are not giants but windmills.”-Don Quixote de la Mancha by Miguel de CervantesI. Summary: Wind energy has many advantages and disadvantages and is therefore subject to close scrutiny as a viable energy source. A key qualification for wind energy is its ability to support the vast industries and businesses of the 6.3 billion people who populate this planet. Furthermore, wind energy must be able to meet the needs of the earth's population in a renewable, reliable and responsible way. In the following document, wind energy will be evaluated based on its energy efficiency/cost, possible environmental implications, its practicality and the various countries that already implement it, the logistics of installing and maintaining the turbines and, finally, any improvements that are looming in the future. future.II. Historical Context: Since the dawn of time, man has relied on the wind to power his creations, especially windmills and boats. In fact, the first wind-powered machines were implemented in Persia as early as 200 BC. However, in the last decade, wind energy has come to the forefront of the race to discover alternative energy sources. America and the world as a whole have relied on non-renewable energy sources for decades. In previous years, the search for renewable energy had been relegated to the background, hibernating while the oil market was booming. However, the use of fossil fuels has been implicated in many environmental issues, not to mention political and economic ones. However, rising oil prices and the questionable safety of America's oil sources have led to a new clarion call for clean, efficient energy. Wind energy advocates argue that these are clean Dutch windmills, resp... Thatched roofs and wooden structures have been replaced with steel, which is strong yet lightweight. Indeed, if Don Quixote were to try to wind these windmills, he would be in for quite a surprise.http://www.engineeringtoolbox.com/docs/documents/1214/wind-velocity-diagram.pngCALCULATIONSThe basic equation P = 0, 5Av3 details the maximum power produced by wind blowing through a given cross-sectional area (A) where v=velocity, ρ=air density and P=power.P = 1/2 ρ A v3P = power (W)ρ = density of air (kg/m3)(At sea level and 20 °C, air has a density of approximately 1.2 kg/m3).A = cross-sectional area (m2)v = wind speed (m/s)NOTE: Air density is directly proportional to density and altitude. Therefore, as temperature and altitude decrease, the density of the air also decreases.
