Windmills: Hero Of Alexandria

For many, the mention of wind energy conjures images of giant white turbines, their blades slowly rotating, stretching off into the distance with no end in sight. This is how it has been portrayed in pictures, but this is not how wind energy truly looks. Photographs in books and magazines imply that wind energy would require these never ending fields. On the contrary, smaller fields where a limited amount of turbines create all the power needed and more for a city that is nearby, or smaller individual turbines creating enough energy for a home or neighborhood without being obtrusive, is how wind energy truly looks. Wind energy harnesses the power of the wind and converts it to other forms of energy, one of the main known forms being electricity.

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.

Wind turbines have evolved over the years to develop into what they are today. People have been using technology for years. For example, it was used for transportation sailboats as early

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 powered machines are developed by the Babylonians. King Hammurabi of Babylon used wind powered scoops to irrigate Mesopotamia. Aside from irrigation and drainage, windmills were also used to ground grain, but maybe later on in history. This is just another advancement making work easier, yet more productive for mankind.

Secondly , windmills are really dangerous for the people living near them or working for windmills. Windmills make really loud noises which might cause health problems. There is a danger of people falling off of a windmill or a part falling down which can injure people. Also , the equipment used to build a windmill is really heavy.

The world is rapidly developing and changing, and all of these changes require a large amount of energy. Today, majority of the energy used today are non-renewable sources, such as burning fossil fuels, and burning fossil fuels creates huge amounts of pollution. To reduce the human footprint that we are leaving behind, people have started looking into alternative energy sources such as wind energy. If we used more wind energy to produce electricity, then it would benefit us economically and ecologically because wind energy is the most cost efficient and space-efficient renewable source, and the potential wind power in enormous. Also, we have an endless amount of wind, and we will never run out.

It has to be AT LEAST 8.7mph to turn a wind turbine. Another disadvantage about wind power is shadow flicker it is when the blades of the wind turbine cause a shadow as it turns. It would cause unwanted repetitive shadows over neighboring houses or buildings, it could be mistaken for power outages or even earthquakes. Finally, the sound of wind turbines they are not silent for the people that live near the wind farms would get unwanted noise in their houses content during the day and at night.

A wind turbine is the opposite of a fan. Instead of using electricity to make wind, wind turbines use wind to make electricity. Wind turbines convert the potential energy in the wind into kinetic energy that results in mechanical power- The turning of the blades and drive shaft. The mechanical energy can then be used for traditional tasks such as grinding grain or pumping water. Modern wind turbines use generators to convert this mechanical power into electricity that can power homes, businesses, schools and other buildings. Wind turbines are often grouped together into a single wind power plant also known as a wind farm, and generate bulk electrical power. Electricity from these turbines is fed into a utility grid and distributed to customers, just as with conventional power plants. Wind turbines come in a variety of sizes and power ratings. Utility-scale turbines

There is a rising commitment towards utilizing clean energy across the world. Wind turbines happen to be an efficient choice to meet some of the demand on electricity. A group of wind turbines connected to each other by electrical cables forms a wind farm. A wind farm produces 17 to 39 times the power it consumes, which is more efficient when compared to other forms of energy such as nuclear power (16 times) or coal (11 times) [1].

Wind energy may seem to be only a clean and non-controversial renewable energy source, but wind energy turbines do have some environmental concerns. The noise factor is one of those concerns, the sound may be disguised by the sound of the wind, but there is a definite noise from the turbines. Analysts and engineers have worked to improve turbines so the noise is reduced. Other environmental concerns are the aesthetic issues they cause to the land, and how the turbines possibly interfere with radar or telecommunications. Also the flying rotors take part in bird and bat deaths. Even though they have these concerns they still have little impact on the environment compared to fossil fuels. These problems have also been either resolved or greatly reduced through technological development. According to the wind energy foundation, “In 2013, roughly 168 million megawatt-hours generated by wind energy avoided 95.6 million metric tons of carbon dioxide (CO2) — the equivalent of reducing power-sector CO2

However, to every dark cloud has a silver lining. There are also benefits of wind power. In the ethical factor, it is a positive step. Using wind power instead of fossil fuels

I can still remember that I’ve made a windmill by a paper in my childhood. I hold my windmill running on the lawn. Currently, wind power has become the world 's fastest growing renewable power source. The earliest use of wind to produce energy is when the Egyptians are said to have used it to propel their sailboats through the water. At 1300’s, the windmill appeared in Europe and was used in the to drain fields. After hundreds of years, people have utilized the wind to do works and used across North America pumping water by the end of 1800’s. It was called steel blades at that time, also had been introduced to improve efficiency. In 1888, windmill was used in Cleveland, Ohio to generate electricity. Now in the 21st

A wind turbine is a machine that converts the wind’s kinetic energy into mechanical energy. If the energy is then directed by machinery it is called a windmill, but if the energy is converted into electricity it is a wind turbine. Wind turbines are old technology but used to meet new challenges. There are two main types of wind turbines: rotating on the vertical axis or on the horizontal axis. The horizontal axis is the most common. These three bladed turbines have the main rotor shaft and electrical generator

The main disadvantage with regards to wind power is the winds unreliability factor. Some areas may not experience strong winds throughout the year which will make the electricity generated from the farm unreliable and the whole project unviable.
