But the electricity created can only feed to that specific region. It is difficult to create transmission lines to move electricity on a large scale to population centers. Wind farm is an area of land that has a group of wind turbines generating electricity to one or more electrical grids. (U.S. Department of Energy, 2013) .
Now wind farm looks like a great idea to generate cheap electricity; however, it is not at all the case. Wind energy is great but wind farms cannot be built in all the places. To generate electricity, winds velocity has to be at least 13 miles per hour. Thus, wind farms have to be built in areas such as hills or valleys were wind velocity is fast enough and continually. Also, large wind farms are a visual blight, and rotating blades can be noisy and endanger bats and migratory birds." Although wind is not always a reliable energy source, it is the world's fastest-growing energy source. (Wind Energy, 2013).
The other faster growing renewable energy is solar energy. The solar energy work in something called solar panels. Solar panels are devices that convert light into electricity. A solar panel is a collection of solar cells. How it works is that the sun transmits energy in the form of electromagnetic radiation. When this radiation is absorbed by the solar cells, it causes rapid electron movement. In the movement, electrons are forced to move in one direction, creating direct current (DC). Then it flows into an inverter which converts the DC into alternating current (AC) producing electricity. The more light that hits a solar cell, the more electricity it is produced. The economic benefits are that sunlight is free, abundant, and dependable. No CO 2 emissions are produced. (Northwestern University, 2013) Solar panels can be set in any place. Some people set them on the roof of their houses, others on free landscapes and others in parking lots. Yes, parking lots can be used as solar energy power plants.
All other energy sources are known as fossil fuels. A fossil fuel is, for example, oil or coal. ... Fossil fuels are burned in power plants. ... Furthermore the use of fossil fuels is limited, whereas the renewable energy sources will always exist. ... In the end the renewable energy is our future, because the fossil fuels would be totally used in less than one century....
Beyond Fossil Fuels "Alternative Energy" In the early 1970's, hardly anyone was remotely interested or concerned about the developing or using alternative energy sources. Fossil fuels were always available and they were fairly cheap to purchase. ... Currently about 7.6% of the energy used in the United States comes from renewable energy. ... About 85% of the energy comes from Fossil Fuels nuclear power provides the last 8%. ... (Dunn 14) The Bush Administration even opposes renewable energy requirements. ...
It begins by describing the current energy needs in rural areas of the world, and the consequences of continued increases in fossil fuel consumption that may occur if renewable energies are not used. ... "Renewable energy technologies have made substantial advancements in efficiency and price reduction, and in many cases they are cost-effective alternatives to fossil fuel-based power plants" (Harrison and Whittington, 2001, pp. 78-79). Renewable energies are also important because they have unique environmental advantages over conventional energy sources. ... As Hayes observes, &qu...
Because of the usage of these fuels "At the end of the 1990s, approximately 90% of the UK's energy needs came from fossil fuels: coal, oil, and gas.... Fossil fuels are cheap and make unfathomable amounts of energy. It seem illogical to switch over to other more expensive energy sources that do not produce near the same amount of energy as these fossil fuels. ... This could be a potential problem that generating energy from fossil fuels do not face. ... Though it may be more expensive to use wind power or other alternate energies the use of renewable resources will not only prevent t...
The use of renewable energy is excellent. ... Due to the convenience and low prices of fossil fuels however, lumber use has fallen. ... Fossil fuels have served as a reliable source of heat for cooking and warmth since the beginning of history. The common fossil fuels are coal, peat, lignite, petroleum, and natural gas. ... Renewable energy sources can. ...
Oil, gas, coal and nuclear fuels are all sources of non-renewable energy. ... Fossil fuels are the number one main source for non-renewable energy that is extracted today. ... Most of the world is currently running on non-renewable sources for the creation of their energy. ... Renewable technologies include wind power, solar power, geothermal energy, hydroelectric power and hydrokinetic energy. ... The continuing use of non-renewable resources such as fossil fuels will one way or another completely deplete our supply of them and force us to look for alternate sources of energy. ...
Renewable Energy: What's the Debate? ... With the rate coal is being used up, along with other fossil fuels, what will the next generation of Americans use for power? ... It can also be converted into a liquid fuel. ... The reaction chamber method is technically not renewable, but the "breeder reactor- produces its energy while recycling its own used nuclear fuel rods (Renewable Energy Primer, 4). ... "Fossil Fuels Energy Crisis."" 12 Dec. 2001. ...
Renewable energy is the energy that is generated from natural sources such as sunlight, wind, rain, and the ocean (Renewable and non). ... This allows more power to be taken in and therefor less fossil fuels will be needed. ... Using renewable energy cuts down on the pollution because the energy to power the waste plants and factories is all natural. ... Instead of using normal fuel to power cars, hybrid cars use fossil fuel energy to energize the car. ... Renewable energy reduces the pollution being put into the environment. ...
Tennessee has recently began focusing on developing clean, locally produced, renewable energy; hoping to become a leading producer of cellulosic ethanol, the bio-fuel of the future. ... The advantages of having wind energy is the supply will always be abundant and it emits no air pollutions like those caused by fossil fuels. ... The disadvantages are that renewable energy is more difficult to produce the mass quantities needed for the supply and demand, unlike the traditional fossil fuel generators. Another disadvantage is that renewable energy depends on the weather and weather is unpredictab...
