Renewable Energy: Wind Power Essay

The first time using a large windmill to use electricity was in Cleveland, Ohio in 1888 invented by Charles F. Brush. The Brush machine was a post mill with a multiple blade picket fence rotor 17 meters in diameter, featuring a large tail hinged to turn the rotor out of the wind. It was the first windmill to incorporate a step up gearbox in order to turn a direct current generator at its required operational speed. In 1891, the Dane Poul La Cour developed the first electrical output wind machine to incorporate the aerodynamic design principles used in the best European tower mills. By

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.

As the global supply of fossil fuels becomes steadily lower, need is growing for new energy sources that are beneficial to the environment and cost-effective. Wind power is one solution to this need. Wind turbines require significant investment, but are cost-efficient in the long term. If construction of turbines is sufficiently increased, the wind may be able to in the future provide a very major portion of global 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

Wind is air in motion, and is caused by the uneven heating of the Earth’s surface by the sun (“Wind”). Because of this, wind energy has less impact on the environment then other energy sources. Therefore, wind can produce electricity through a turbine or windmill. A wind turbine is a device that converts kinetic energy from the wind into electrical power. (“Wind Turbine”) In order for a wind turbine to work there are many properties that must be present such as: wind, wind speed, location with the right wind, as well as other characteristics that come to play such as short and long term fluctuations and the distribution of wind direction.

Aesthetic issues are highly subjective by nature. To prevent arguments of the visual nature, placing fewer turbines farther apart could make the overall appearance less offensive to the eye against a natural landscape (Wind Energy Development).

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.

Wind Power is power obtained by harnessing the energy of the wind. Uneven rays, temperature, and the rotation of the earth are what cause wind, warm and cold, which in turn provides energy. Wind turbines are the main items used to provide energy from the wind. Wind turbines have large blades that turn in a circular motion at the top of the tower. As the blades turns, it causes a shaft to turn as well inside the tower. The shaft is connected to a generator which generates electricity. These wind turbines are placed on either onshore or offshore wind farms. Onshore wind farms are placed on ridges, hills, and seashores, since those are the best areas to catch wind. On the other hand, offshore wind farms are not only very difficult to build and maintain, but on the bright side, pick up more wind than onshore wind farms since they are placed in the sea (Fridell pp. 13-18). This source of energy is good to use since it is very efficient because the wind usually occurs around the world. Wind energy also provides jobs. Wind jobs are growing 12 times faster than other industries. And, a wind turbine technician is the fastest growing profession in the United States (Samuelson 2017). Also, just one wind turbine can provide energy for several houses. For example, In the book, Earth Friendly Energy on page 34, It states, “In 2005 the total was 58,982 megawatts. On the average, one megawatt of wind power can serve 160 U.S

“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

Most of the offshore wind turbines are constructed in waters about 100 feet deep having a monopole that has been implanted straight into the seabed. More multifaceted and costly tripod structures are required for the projects that are constructed further offshore so that a stable footing is

We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.

The type of turbine purchased depends on the wind speeds, the electricity the grid can absorb and the cost of the turbine. According to the United States International Trade Commission in 2008 there were 13 turbine manufacturers with two United States manufacturers generating 50% of the market. The chart below shows the dimensions of a turbine for three of the top manufactures.

The main cost of wind energy is in the initial investment in the construction of a wind turbine; the upkeep cost is generally marginal and lower than one cent per kWhr. In general, wind power works by having air molecules move across the turbine blades transferring kinetic energy from the molecules to the turbine, causing it to turn. As it turns, the mechanical energy can be used to perform tasks such as grinding grain. More commonly, the turbine turns and utilizes a power generator to convert the mechanical energy to electrical energy.

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.
