11th Century: Windmills And Food Production

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.

Wind is a form of solar energy so when it is used it creates electricity. Electricity is a physical phenomenon associated with fixed or moving electrons and protons. The wind power development was a step forward for the use of electricity on how to generate more electricity using the wind. The accomplishments for electricity is that Senegal used 10MW for a wind farm and they gave a positive report and is now using it since the second half of 2005. (Dodge) Another thing is during the Second World War; small wind generators were used on German U-boats to recharge submarine batteries as a fuel-conserving measure. The good thing about wind power is can produce electricity at night as well as during the day and that it is plentiful, renewable, and it reduces the greenhouse gas emissions. (ERIC) The Wind Power would be cheaper to develop electricity and it is less harm to our daily lives.

The way the wind turbine works is when the wind blows, the blades on the wind mill (or turbine) are spun to run the motor that is attached to the back of the turbine. The motor transfers its energy through wires to a substation where the energy is transferred into electricity that can be useful for residential and commercial areas. The energy is then delivered through wires across the country.

Water turbines are near the oldest ways to run power without using fossil fuels. The new age had turned these into hydro turbines that generally reside in dams. These machines take similar shape to wind turbines. Hidden in the base of a dam, there is a very large turbine that, in a simple explanation, when water runs through it spins. With the energy used by the spinning turbo it is turned into different power sources that are stored into power cells. Way back in time, this idea was used in power mills. Those old spinning wheels on the side of houses that rotate with water pressure. The first power plant was constructed in 1879 at Niagara Falls, Canada. In the United States the first plant was in 1882 in Wisconsin. These extravagant machines seemed marvelous, but that is no longer the outcome. The current age hydroelectricity dams are currently being shut down for harmful aspects triggered from the giant production. Causing an environmental failure to marine life and habitats all around. The possible outcomes are: changing the oxygen levels in the water that cause organisms to perish; fluctuating water levels that cause different

Everyday, this mysterious force known as the wind blows constantly around planet Earth. No one knows why the wind blows, but that did not stop individuals from harnessing its power. In past times, Persians and Daniel Halladay were able to invent their own versions of the windmill. Each design served a slightly different purpose than the other.

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.

When the wind is blowing on wind turbines it produces electric power, Fans are old techniques used in the mills and then the water pump, but now it has developed the technology and has become used for electric power production.

The first reason is that they are really expensive to build. It takes $1.3 to $2.2 million to build a windmill. Wind turbines under a 100 kilowatts cost $3,000 to 8,000. All the parts of the windmill are located at the top. Also you have to have a lot of people to operate it.

“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 afterward, 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

In 1831, scientist Michael Farday discovered the first form of electricity. He found that when a magnet moved inside a copper coil it created what is known as an electric current. This invention is known as a turbine generator. Even today, in full sized power stations this simple invention is still used and works very effectively. These power stations create mass amounts of energy to turn the turbines. Most of the time the energy is made from the heat, for example when coal is burned. More environmentally friendly power stations use wind or flowing water to turn these turbines. This is known as renewable energy because it will not run out, unlike when oil and coal are used.(3)

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.

For this last case study, we focus on the topic of wind power, the details of the Catamount Energy and the Glebe Mountain Wind Farm Case, and the importance of wind power around the world. It was very interesting learning about the history of the wind power and how it made an impact in the world. To start it off, it is important to understand the significance of wind power and how it plays in important role in this case study. The earliest appearance of wind power was traced back to 2000 BC in ancient Babylon. It was used to grind grain and pump water. Over the next thousand years, windmills began to spread to the Islamic world, China, and India. The usage of windmills traveled to the western world during the medieval times and slowly began to adapt for use of irrigation canals. During the 19th century, the steam based railway system had made its introduction to the world, while using windmills to pump water into train engines. In Europe, windmills were the primary energy source during the 19th century until the steam engine came through. Then during the early and mid 1950s, that 's when government efforts to extend this windmill power grid to every American household ended the market for these machines. In record, the first largest windmill usage to generate electricity was built in Cleveland, Ohio in 1888 by a man named Charles F. Brush. The Brush windmill was successful and for over twenty years it is being operated. A Dane, Pou La court designed the first wind machine

Nowday, we use the fossil fuels for many things. Fossil fuels are the fossils of plants and animals that died. We need fossil fuels for electricities, cooking, and even shampoo we use every day. The most common fossil fuels was coal, oil, and gases, but now scientist estimated that after 150 years, we will be running out of fossil fuels. Another fact was that the digging up the fossil fuels create a huge amount of pollution, and it really harms the environment.The best solution was using the wind power as our energy. Wind power is electricity that is powered by the windmill, this power is renewable, and sustainable, which means that it would be always able to get electricity from it unless there aren’t any wind. The wind power worked

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

Early recorded history shows people have used energy from the wind, wind energy propelled boats along the Nile river as early as 5000BC by 200BC, simple windmills were pumping water as well as grinding grain in Persia and Middle East. Using small windmills, wind energy has also been used to pump bore water (particularly in rural areas), wind energy is the fastest growing
