Our sources of oil or petroleum are running out. Although new oil deposits are being discovered every year, the amount does not equal to levels of our annual consumption. Petroleum also produces carbon dioxide, which contribute to greenhouse warming. In the effort to reduce the need for oil or petroleum as a source of energy many solutions are being discuss such as wind power, solar power, coal and the use biofuels such as ethanol as would be alternative fuel sources. In this paper, the pros and cons of alternative energy sources are discussed to see if they are the solution to replace oil as an energy source.
An energy source that has been in use for many centuries and is use in many third world countries as an energy source to pump water from wells and to mill grain is wind energy. Wind power, is wind energy channels by power of the wind to push the blades of wind turbines. The rotation of turbine blades is transferred into electrical currents by means of an electrical generator. Wind turbines are constructed in numbers on wind farms. Wind farms are able to generate electrical currents on a large scale. National electrical grids use wind farms as well as small individual turbines used for providing electricity to isolated locations or individual homes (Turk & Bensel, 2011). According to Journal for Nature Conservation In 2005, wind-powered generated 60,000 megawatts, that made for production less than 1% of worldwide electricity use (Kikuchi, 2008).
Wind power produces no pollution, there are no harmful by-products left over by wind energy, wind energy will never run out it is a renewable source of energy. As long as the earth is rotating around the sun, wind will be generated unlike oil that has a by produce of carbon dioxides that harmful to the ozone by adding to greenhouse gases. Where oil as an energy source is not depending on the weather to produce energy, wind power is depended on the weather, which make it not consistent energy source. . Consistent wind is needed for unremitting power generation, therefore, when the wind speed decreases, the turbine dawdles and less electricity is generated which means a decrease in ready available energy. Both oil and wind energy structures are considered an eye sore on the landscape. Wind turbines effects of the mortality rate of birds populations. The location of wind turbines and the physical qualities of structures, the height and the use of lighting around the wind turbines , are affecting the rate of bird-strike due to a range of wind turbines and the repercussions of collisions is a decrease in the bird populations(Drewitt & Langston, 2008). The side effect of oil extracting is water and air pollution, which affects no only wildlife but the environment as a whole negatively. (Turk & Bensel, 2011)
Another alternative energy that is currently in use in many countries is solar energy. Solar energy as wind energy is solar energy is a renewable source of energy, as long as we have...
