I’m happy to say that I chose this topic as I learnt a great deal of information while writing this report. It was while developing the working model of Windmill that encouraged me to do research that lead to this report. Thank you Wikipedia.
As always, I prevailed upon my Teachers to provide me the knowledge. They taught me how to think and apply that to my work. Rebecca Maam, my science teacher, has been with me from the beginning. She is insightful, thoughtful and encouraging. When I think of what she has done for me, I feel very lucky to have such a good teacher.
I owe thanks most of all, to my parents. Without their support and encouragement, it would not have been possible for me to write this report.

Introduction
A windmill is a three bladed machine which converts the energy of wind into rotational energy by means of blades. Originally windmills were developed for milling grain for food production. In the course of history the windmill was adapted to many other industrial uses. An important non-milling use is to pump water, either for land drainage or to extract groundwater with wind pumps. Windmills used for generating electricity are commonly known as wind turbines.

Topic
A windmill is an engine that is powered by the wind to produce energy. Often they are in a large building. The energy windmills produce can be used in many ways, traditionally for grinding grain or spices, pumping water, sawing wood or hammering seeds. Modern wind power machines are used for generating electricity and are more commonly called wind turbines.
A windmill is one of the most energy efficient ways to pump water from the

    In the book The Boy Who Harnessed the Wind by Bryan Mealer and William Kamkwamba, wind energy is effectively used. Windmills are a great way to produce clean energy from the wind, however, lots of Americans don't like windmills. They argue that windmill ruin the landscape, they are too expensive, and they only work when the wind is blowing. Here are some counter arguments to their complaints:…

    Wind power is generated when the wind speed is strong enough to turn the blades of giant fans, which in turn turns the turbine inside the machinery. The major setback for implementing wind power, as an alternative source of energy is the fact wind speed must be at least greater than 10 miles per hour, and this is not a constant situation (Green living, 20130).…

    Wind Farms in Cumbria

    Wind turbines generate electricity through this process: the wind turns the blades which then spins a shaft. The shaft connects to a generator which produces electricity. The UK is an ideal place for wind turbines because we are one of the windiest nations in Europe. Cumbria in particular is an ideal place to build new wind farms because it is a very hilly area and it has a long coastline; making the area very windy. There is already a wind farm in the village of Great Orton and so far it has been a success. It has supplied 2,000 homes and has saved about 8,530 tonnes/year of greenhouse gases. It also gives farmers extra income in the area because the wind farms are built on their land.…

    Long time ago, ancient mariners used sails to capture the wind and explore the world. Farmers once used windmills to grind their grains and pump water. Today, more and more people are using wind turbines to wring electricity from the breeze. Over the past decade, wind turbine use has increased at more than 25 percent a year. Still, it only provides a small fraction of the world 's energy. Therefore, wind power or wind energy is the energy extracted from wind using wind turbines to produce electrical power, windmills for mechanical power, windpumps for water pumping, or sails to propel ships.…

    Weeks ago, when I investigated our farm and surveyed the ground, I discovered that the knoll is the highest point on the farm, and it is certainly the ideal place to build the windmill on. Once the windmill is built, it can generate electricity through a dynamo with the energy from wind. This amount of electrical power will be so enormous that it will be able to run a circular saw; it will be able to run a chaff-cutter, it will be able to light up every stall in the farm, and warm them in winter.…

    Windmill, machine that converts wind into useful energy. This energy is derived from the force of wind acting on oblique blades or sails that radiate from a shaft. The turning shaft may be connected to machinery used to perform such work as milling grain, pumping water, or generating electricity. When the shaft is connected to a load, such as a pump, the device is typically called a windmill. When it is used to generate electricity, it is known as a wind turbine generator.…

    The wind power industry first developed in Iran around 200 B.C. The first windmills were vertical axis wind turbines, which were used for pumping water and grinding whole grains for food consumption. The Chinese, Romans and Afghans all used windmills around this time for similar use. In the 13th century Holland started developing large horizontal axis windmills. These four-blade windmills were larger, carried more torque and wind speed and could do more work than other windmills previously designed. These windmills were also used for grinding and pumping water, but on a more productive level.…

    For many years, people have been harnessing the power of wind. Wind propelled boats down water and simple windmills were used to pump water and grind grain. But credit goes to the Dutch who refined windmills so that they could drain swamps and lakes, and in the 19th century, settlers took this concept with them to the New World. There, windmills were used to pump water for farms and ranches, and later to generate electricity for homes and industry purposes. Industrialization caused a decrease in the use of wind power, but also began the development of larger windmills to produce electricity. The result, commonly called wind turbines, could have been found in Denmark as early as the 1890s.…

    With the reckless energy demand in the 21st century and the growing of global warming, which made by environmental pollution, energy supply has become the constraint and an obstacle to the economic development of many countries. To solve these kinds of puzzles, which can respond to the climate and energy challenges., people now pay more attention to all kinds of new type of renewable energy, which is good ecologically. Wind power is one of the optimal energy, which has great prospects. Wind is the movement of air across the surface of the earth, from areas of high pressure to areas of low pressure (Anon, 2010). Wind goes through the turbine motor then drive the machine to produce electricity, which is wind power generation. It is currently already used widely in many jurisdictions because of the attractiveness, significant negative externalities, and the performance which human society civilization progresses. Wind energy as an inexhaustible, clean, and also environmentally friendly energy, which is gradually paid more attention by people around the world. However, it also has some problems. Wind power generation needs to pay a lot to achieve operation, which made various countries to have a cautious consideration about that. But as wind turbine technology improves, costs may come down, become cheaper as turbines continue to grow in size and manufacturers drive down costs. So in this essay will make a sketchy overview of wind power generation.…

    With diminishing fossil fuels and the dramatic intensification of greenhouse gas pollution, there have been numerous developments in alternative renewable energy sources (IPCC, 2013). This has led to an increase in the number of wind farms around the world over the past three decades, with them becoming a critical part of many countries electrical network (E.ON, 2004). Countries are now becoming reliant on the contribution of electrical energy from wind turbines, with Denmark receiving 33% of their energy in 2013 from wind power (Vittrup, 2014). It is therefore essential to recognise the…

    “A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush, who ran his entire Euclid Avenue mansion off of one for 20 years, which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn't rise a great deal afterwards, this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose ‘fuel’ is free and will never be exhausted” (3) with the pros and cons not completely weighed out as to whether it will be truly beneficial or not. The two main issues regarding wind turbines are the environmental effects that they have and the cost effectiveness of building them.…
