11th Century: Windmills And Food Production

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.

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.

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.

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.

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

“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

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.

Following the recent developments in renewable energy sources, wind turbines have been one of the primary devices focussed on. Basically, wind turbines are devices that convert the kinetic energy from the wind into electrical power for human usage. “Wind farms” are created in very windy places to harness this energy.

This was first discovered during the 18th century and the PV cells themsleves were developed at Bell Labs in 1950 primarily for space use. Today, the Hubbell telescope uses solar panels for its energy requirements. NASA continues to regularly use solar energy with much of their machinery, since electricity is dangerous in space. The cost for PV cells has dropped in the last few decades and now many rural health clinics can use it for refrigeration, water pumps, and for small scale power generation. Also, EXXON is the second largest producer of solar cells. It’s also very important to mention wind turbines, the modern equivalent to the windmill. These are mounted on a tower to capture the most energy. The “lift-and-drag” of the wind causes the rotor, which mounts the blades, to spin and the turning shaft spins a generator to make electricity. You may be asking “how does this relate to solar power?” Well, pressure variates between areas because of solar energy. This gives the power to these wind turbines.

Wind turbines use the kinetic energy created by wind currents to produce electrical energy in a generator that spins alongside the turbine’s rotor blades. The generator uses powerful magnets and coils of wire in an electromagnetic field to convert the mechanical energy into electrical energy (Kid Wind Project, Inc., n.d.). From there, the energy is sent to a nearby substation where it’s converted into high voltage electricity and transmitted across the national

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)

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
