Using Wind Power as an Alternative Energy
Energy is the ability to do work. It surrounds us in all aspect of life. However, the ability to harness it and use it, as economically as possible, is the challenge before mankind. Alternative energy refers to energy sources, which are not based on the burning of fossil fuels or the splitting of atoms. The renewed interest in this field of study comes from the undesirable effects of pollution both from burning fossil fuels and nuclear waste by products. Fortunately, there are many means of harnessing energy that have less damaging impacts on the environment. One example wind power. Wind energy is a clean and renewable source of electric power and is also the world's fastest growing energy

A wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns a blade, which spins a shaft, which connects to a generator and makes electricity. Modern wind turbines fall into two basic groups, the horizontal axis and the vertical axis design. Horizontal axis wind turbines have blades that spin in a vertical plane like airplane propellers. The blades have a special shape so that when wind passes over them, it moves more rapidly over one side. This creates a low pressure behind the blade and a high-pressure area in front of it. The difference between these two pressures causes the blades to spin. The blades of a vertical axis wind machine work on the same principles as horizontal axis machine. The shape of the blades causes the pressure to differ when the wind blows over them. This causes the assembly to spin. In a vertical axis machine, however, the blades spin in a plane that is parallel to the ground like an eggbeater. Wind turbines are made in a variety of sizes, and therefor power ratings. The largest machine, such as the one built in Hawaii, has propellers that span more than the length of a football field and stands twenty stories high. It also produces enough electricity to power fourteen hundred homes. A small home sized
Wind turbines have altered the way that we get our energy. Wind turbines are used to harness wind power and turn into electricity. They are comprised of usually 2 or 3 blades that are connected to a shaft that was attached to a generator which then turns into electricity. Although we now generally use it to produce electricity, wind energy was originally used in the form of windmills to do chores and housework. Because of the rapid increase in the use of wind turbines, it has added jobs and changed the way we get energy.
The wind turbines are made and created from a local power plant in Valeria and it helps create kinetic and solar energy. The Wind Power is sustainable because wind turbines are a conversion to kinetic energy and the wind is mechanical power. But the
An ideal place to have a wind turbine farm would be near mountains, but Mariculloch is more flat than it is near mountains. Wind turbines blades are made so that the air pressure is uneven, this is what makes it spin. When the blades begin to spin, it turns a shaft which also spins a series of gears that are connected to a generator, that is able to produce a large enough amount of energy to power many homes.
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.
In the Book Building Green Skyscrapers by Mary Reid, the wind turbine is the best because it can be be use for two uses. To start wind turbines can power up buildings. The narrator stated “The wind spins the huge blades of a wind turbine... the turbine runs a machine called a generator. “ (Reid 5). This shows that this can save energy because all extra energy goes into the batteries for later use. Furthermore, Wind is the best type of source. The narrator stated “Wind power is one free source of clean electricity… wind does not produce harmful gases… Nobody needs to worry about running low on wind” (Reid 4). This explains that wind turbines are the best because you can always count on wind to help if you need. In conclusion, Wind Turbines
Today, we have what is known as wind turbines. These large structures are used as a renewable and free energy source. The way a wind turbine works is very simple. As the wind blows, it moves the blades, which then turns a generator and makes electricity. These wind turbines are only a small source of energy because they work about 65 to 90 percent of the time. When many wind turbines are placed together in one area, it is known as a wind farm. The majority of wind farms are found in Texas and California. Wind farms are hoped to be spread all across the country to become a more prominent source of energy that is not only renewable, but also free.
People used windmills back as early as 5000 B.C. They were pumping water and helping grind grain. In the 11th century, windmills became assets to farmers by helping food production. The idea spread, and along with helping food production, it also helped pump water, which, after much modification, became able to generate electricity. Daniel Halladay was the first person to design a wind turbine in the US. He did it in Connecticut, and the windmill became successful and helpful on farms. Wind turbines have gotten bigger over time, allowing them to generate more electricity due to the fact that they harness more energy with bigger rotors. Governments started to advance technologies, and once they teamed up with NASA, it led them to create a wind
Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Click on the image to see an animation of wind at work.
Jason M. Everett claims that “The kinetic energy in the wind can be used to turn a propeller-like wind turbine connected to an electric generator. The generator converts the kinetic energy into electrical energy, which can then be used to power a wide range of things.” Because of this, “Wind energy comes from the sun. As solar radiation heats the earth’s surface, hot air rises and cool air fills the voids. This air movement is defined as wind energy. Wind that is harnessed via mechanical means is also referred to as wind energy.” Jason M. Everett states
The lab tested various properties associated with wind turbines while measuring the effect on the power. It was shown that wind turbines can supply a significant amount of energy and power. This wind energy has an important application with wind turbines across windy areas of the United States. These turbines can provide power as a replacement for nonrenewable resources. Although wind energy might not be the most vital form of energy currently, it could become a very important alternate energy source in the near future. Wind turbines can be placed all across the United States wherever there is a strong amount of wind. When talking about implementing wind energy there are a lot of things to think about.
“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
There are basically two sorts of wind turbines: horizontal-axis design and vertical-axis design. Horizontal-axis wind turbines are the most common type used and can have various sizes. This type of turbine has a horizontal rotor shaft and generator usually located at the top of a tower. The propeller-type blades are used to capture wind thus are oriented into the wind, for instance for small turbines a wind vane is used, or if
Wind turbines, formerly known as windmills, convert the power of wind into electricity. More specifically, wind creates kinetic energy, which causes the blades to turn. Those blades are attached to a rotating shaft that creates and sends electricity to a power grid (EERE, n.d.a). The sun’s rays unevenly heating the planet creates wind, reasons for the inconsistent distribution of heat are uneven terrain and the earth’s rotation around the sun (EERE, n.d.b). It is considered a renewable energy since there will be wind as long as the sun heats the planet. Some of the most common placed for this to happen is in large bodies of water and hill sides, anywhere wind is created.
Energy is a crucial necessity and with the ever increasing need for it and the high and fluctuating prices of oil, researchers are constantly coming up with newer and more sophisticated alternative sources of energy. However, energy comes at a cost, as it is either expensive or it possesses high health risks. This essay presents the concept of energy by discussing the two major types of energy, the various forms it could take, including renewable sources of energy, energy conservation and above all it talks about the safest and cleanest alternatives.
In order for these turbine's to operate well and efficiently with as little maintenance as possible, it is necessary for the turbine's to have well-constructed, well designed turbine blades. They have to have certain properties that enable them to withstand high
