Essay about How Wind Turbine Improved the World

In a growing world, electricity production is becoming a problem due to coal fired electrical plants releasing millions of gallons of greenhouse gases, ecological problems with pollution in water, and health risks concerning workers and people living nearby. But with new technology and advances in renewable energy sources, wind energy is becoming one of the most popular energy sources for many states.

Imagine getting free electricity, or electrical company’s paying you instead of you paying them, today’s windmills just might make this possible. Windmills dating back as far as the 1400’s have been used to turn wind into useable energy for grinding and pumping. Today’s windmills turn turbines to make electricity. They are popping up all over the United States, but the United States is way behind other countries in the development of wind energy. Countries like Denmark, Germany and the United Kingdom are investing billions of dollars into wind energy, including off shore wind farms. Germany is holding the top spot in the production of wind-generated electricity. Denmark, being one of the smaller countries in Europe, produces twenty percent

Wind is air in motion, and is caused by the uneven heating of the Earth’s surface by the sun (“Wind”). Because of this, wind energy has less impact on the environment then other energy sources. Therefore, wind can produce electricity through a turbine or windmill. A wind turbine is a device that converts kinetic energy from the wind into electrical power. (“Wind Turbine”) In order for a wind turbine to work there are many properties that must be present such as: wind, wind speed, location with the right wind, as well as other characteristics that come to play such as short and long term fluctuations and the distribution of wind direction.

Have you ever driven down highway 30 in west central Iowa at night, looked out the window and seen hundreds of red flashing lights? How about driving through north Lincoln and seeing two enormous white turbines spinning in the wind? If you did not know previously, the red flashing lights at night and white turbines are windmills used for generating power. These windmills can produce 2.5 to 3 megawatts of electricity daily. Wind power can be easily used to generate electric for both personal and public use. Looking at the benefits of wind power over fossil fuels, uses of wind power for personal and public use, and the effects of global warming on wind power, you can decide if using wind energy is a good option or not.

Windmills date as far back as 200 BC. The first windmill was known as “Hero of Alexandria”, located in what is now known as Iran, but was not too successful. These windmills were tweaked over many years to have a well functioning purpose. The main purposes of the windmills in ancient times were water pumping and grain grinding. Windmills have been used for thousands of years, allowing for a revolutionary way of completing certain tasks.

Did you know that windmills are used to power homes across America? I think wind energy should be used in America, because "Wind power is an increasing valuable source of energy," says Shirley Anne Ramaley.  In other words wind is a reusable source of energy that we can use forever.  Wind energy is a great source of energy, but it can cause a few problems.  Let me tell you a little bit more about wind energy.

One of the most important environmental advantages of wind energy to the air that it is a renewable source of energy. Indeed, wind is one of the natural phenomena on the surface of the ground that people deal with on a daily basis. Therefore, wind power is clean and renewable forms of energy, and it can be utilized in several aspects. For example, it can be converted into electrical energy through turbines and into mechanical energy by using windmills. In addition, wind power is used to move the windmills for grinding grain, as well as in the transfer of water, but

What is a wind turbine? A wind turbine, is the process in which a turbine takes wind and produces clean energy(electricity) free from harmful gasses, to power this turbine wind is needed but how is wind obtained? What is wind? “Wind is a form of solar energy and is a result of the uneven heating of the atmosphere by the sun, the irregularities of the earth 's surface, and the rotation of the earth”(How Do Wind Turbines Work?). In other words wind is a renewable source such as solar energy. It 's produced when warm air rises to the atmosphere and later on is cooled down making it sink down, as warm air goes up cool air takes its place causing what we know as wind. Therefore the way a wind turbine will perform

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

Since 400-500A.D, people used windmill energy in farms for grain grinding and water pumping. In 1888, the first wind turbine that generated electricity was discovered by Charles F.Brush in Ohio, USA. However, there are limitations on speed.

Wind energy is essentially the conversion of the kinetic energy from air molecules in motion to mechanical energy which is generally then converted into electrical energy. People have used wind power since 700 AD in

One of the main contributors of the increasing demand for energy is the fast global economic growth. Other conventional fossil fuels such as coal, oil and natural gas which have been a key source of energy since industrial revolution, are not only facing depletion but they have become a source of concern regarding its serious adverse effect on our environment (Abbassi, Premalatha, Abbassi & Abbassi,2013). Hence, the pursuit to develop renewable and clean energy sources, such as solar, wind and hydro power is energy needed. Wind power is considered as one of the cleanest sources of energy, with mild impacts on the environment, on wildlife and on human life, as far as the production of electricity from modern wind turbines is concerned (Leung &Yang,2011).

As the wind passes over the blades it creates lift which causes the rotor to turn. The blades turn a low-speed shaft inside the nacelle. The gearbox connects the low speed shaft to the high speed shaft and increases the rotational speeds from 30 – 60 rotation per minute (rpm) to around 1000 -1800 rpm. This is about the rotational speed required by most generators to produce

It includes a motor controller. The function of the motor controller is to convert the DC into AC. Mechanically, these motors have simpler design than the other types of the DC motor as there is no requirement of transferring power to the spinning rotor from the outside of the motor. The position of the rotor is sensed by the control of a “Hall Effect” sensor or any other such device to optimize torque and regulate speed.
