Wind Energy â€Å"Take care, your worship; those things over there are not giants but windmills.† -Don Quixote de la Mancha by Miguel de Cervantes I. Abstract: Wind energy has many pros and cons, and thus is subject to much scrutiny as a viable energy source. A fundamental qualification for wind power is the ability to support the vast industries and the enterprises of the 6.3 billion people that inhabit this planet. In addition, wind power must be able to meet the needs of the Earth’s population in a renewable, reliable, and responsible manner. In the following paper, wind energy will be evaluated based on its energy/cost efficiency, possible environmental ramifications, its practicality and the various countries already implementing†¦show more content†¦IV. Discussion and Conclusions: Wind Power can be defined succinctly as the kinetic energy present in motion that can be converted to mechanical energy. The basic turbine uses mechanical blades that rotate due to the force of the wind to drive a generator that in turn sends electricity through a transformer into the power lines that supply energy to homes and businesses. The following diagram details the above-mentioned process1 Energy/Cost Efficiency Modern technological developments have helped transform wind energy into a more accessible and practical power source. According to the website, the following criteria can be used to evaluate the efficiency of wind energy2: Although wind power is completely free and will never be depleted, a concern shared by many is the sheer impossibility of sustaining the wind. Because of this inconsistency and the ever-changing speeds of wind, power is producing at varying levels. Also, wind turbines have a certain â€Å"envelope† in which they operate. According to the author of the website mentioned above, this range is from 10 to 33 miles per hour.

Wind Energy is the conversion of wind power to electrical energy. Wind power is an inexpensive form of energy compared with coal, gas or fossil fuel powered plants. Wind energy exists over wide geographic areas (Onshore and offshore). Increased deployment of wind energy (Renewable energy) and energy efficient techniques haveRead MoreWind Energy And Wind Power1225 Words   |  5 PagesWind Energy and Wind Power Wind is an abundant resource on our planet. And this resource has particular characteristics that make it advisable for us, human beings, to utilize it in order to generate electricity. It is considered a type of solar energy, since the wind is produced by the differences of heating of the atmosphere of our planet performed by the sun, some abnormalities on the terrain of the planet, and also the rotation of the Earth. Some conditions can alternate the patterns of theRead MoreWind Energy : Wind Power1049 Words   |  5 PagesWind energy is the use of air flow through wind turbines to mechanically power generators for electricity. Wind power has been used as long as humans have put sails into the wind. Wind power is an alternative to burning fossils, is plentiful, renewable, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little , or barely any land. Wind power gives variable power which is very consistent from year to year, but it has significant variation over shorter time scalesRead MoreThe Energy Of Wind Energy2438 Words   |  10 PagesABSTRACT:- ​The main purpose of the wind energy is to create energy source which is pollution free and come with a reasonable price. The wind energy used in wind turbines are increasing their demand and becoming popular in the green energy world. Since the rebirth or rapid growth of wind energy took place from early 1980. The growth of the industry has been more than expectations. As all the good things the wind energy poses certain negative impacts of having high maintainer cost. Repair and dataRead MoreWind Energy And Wind Power1799 Words   |  8 PagesWind power Wind energy or wind power is extracted from air flow using wind turbines or sails to produce mechanical or electrical energy. Windmills are used for their mechanical power, wind pumps for water pumping, and sails to propel ships. Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.

With the emergence of new technologies and the use of new resources, the windmill and wind turbine has been disregarded for the more efficient oil and coal production of energy, as they are more consistent and produce more power on average than wind can. This is fast changing though; the oil price rise of the late twentiethRead MoreWind Energy and Turbines659 Words   |  3 Pagesof energy that can be used to generate electricity. When you think of the word energy, what comes to mind? For m e, I think of having the ability to do wok, whether it is moving an object from one place to another, compressing a gas, producing heat, sound, or light, and having the ability to power something. One very important source of energy that has become very popular in todays world for a means of power generation is wind energy, wind power, or also known as a wind turbine. What is Wind EnergyRead MoreWind as a Source of Energy799 Words   |  3 PagesWind is a very important source of energy. According to WindSolarEnergy.org, â€Å"[Wind energy] is now the fastest growing segment of renewable energy.† The use of wind is a safer way to produce energy than exhausting fossil fuels. When the sun is hiding behind the clouds and not shining brightly, wind is usually created which is then used to convert wind into wind energy. It also depends on the weather condition of the day. It is always available when solar energy is not. Locations Where Wind PowerRead MoreFactors of Wind Energy1843 Words   |  8 PagesWind Introduction Wind is created by temperature gradients , created by differences in heat received on the surface of the earth as a result of incoming radiation from the Sun. These gradients depend on the angle of the incident sunlight, as well as the characteristics of the terrain and are vital for the formation of specific regional climates. Land and water masses have different heat capacities which lead to an uneven heating of the planet’s surface. As there are different temperaturesRead MoreDesigning A Wind Energy Into Electrical Energy With The Help Of Wind Turbine1161 Words   |  5 Pagesvehicle which can convert a wind energy into electrical energy with the help of wind turbine.
