Essay on Wind Energy

Although wind energy is one of the most expensive ways of producing energy, its benefits are far greater than its alternative energy production sources. Wind energy is a growing business mainly in the Midwest and

These examples suggest that wind power will be used in ways that correspond to each needed capacity and purpose. In the article “Wind Energy: An Untapped Resource,” the Wind Energy Association estimates the potential amount of wind power generation capacity in the U.S.A. at 10,777 billion kW/h, which is three times the electricity generated in the U.S.A. today. However, it also predicts that we are unlikely ever to use even half of that potential. In fact, in 2000, the U.S.A. was using less than 1% of that potential! This is because wind power is not always the superior method, and there are some problems still to be solved.

One of the fastest growing energy sources in the world, wind power is a globally advantageous renewable resource.

With the difficulty’s wind power companies are having inland, there is a big push to go offshore, and the great lakes seem to have every component for a successful wind farm. (Lots

Nodaway county has approved a new, 23,000 acre, wind farm for which construction will begin in 2019.

Another benefit to wind energy is the environmental offset it has on more local environments that traditional energy sources are destroying. Oil, gas, and coal power plants destroy local environments by polluting the water and soil and wasting tons of water. Wind energy will mitigate this problem because Wind power does not require any water and only requires a very small land footprint. This will not only save us from environmental harms from the water and soil it will also help prevent droughts and increase the water available to us. This is particularly critical when we have places like California that are running bone dry currently. Thermoelectric power plants (majority of coal, nuclear,

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.

Wind turbines can be placed on land or water, and can be placed at different altitudes, making the search for wind farm locations easy. Wind farms can be placed on traditional farms as well.

“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

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.

This research topic involves the study of environmental science. The following characteristics of wind power and hydropower will be discussed: background information that includes definitions and previous research, how wind

Fossil fuels are having great impacts toward nature such as global warming and greenhouse effect. Plus, the depletion of it contributes to the rising price of petroleum. Therefore, wind power rise as it is a source of clean, non-polluting renewable energy (Nash, 2008). This type of energy generation provides us with loads of benefits environmentally and economically.

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.

The scope and project approach will be followed by a literature review which will discuss the variables mentioned in the Figure 6 in detail and identify the factors which contribute to the efficiency and possibility of installing a wind turbine

While operational costs have always been an advantage for wind power, high capital cost per unit constrained its economic viability in the past. Technological advancement has made it possible to build larger and lighter turbines, which can capture more energy leading to a substantial fall in capital cost per unit. Over the last two decades, there has been a 55-fold increase in yearly electricity output from wind, partly because the swept area is 25 times larger (due to larger turbines) and partly because the tower height has increased substantially, and wind speeds increase with distance from the ground.
