Extract of sample "Energy"

Download file to see previous pages The major difference between renewable energy and nonrenewable energy is the ability of renewable energy to renew. For example, wind energy is a renewable energy source which will be available in this world as long as this world remains in its present state. On the other hand same thing cannot be said about nonrenewable energy. For example, oil or natural gas energy sources are exhausting day by day and it is not replaced by any of the natural means.
Because of the nonrenewable nature of nonrenewable energy, this energy source is going to lose its significance in near future or 50 years from now. Renewable energy sources will gain prominence in near future itself. Moreover, nonrenewable energy sources are causing severe environmental problems like air pollution, water pollution, global warming, climate changes etc and therefore it is difficult to rely on nonrenewable energy sources further. For example, “Air pollution, thermal pollution, land devastation, groundwater pollution, acidification of streams and rivers, erosion, subsidence of land caused by underground mines, hazards to miners, and, of course, global warming are all recognized as part and parcel of coal’s utilization” (Smith, 2009, p.162). On the other hand renewable energies such as wind energy, tidal energy, solar energy etc are causing little or no damage to the environment.
In my opinion, solar energy seems to be the future energy source. The major advantage of solar energy is the less environmental problems it can generate and its abundant nature. Solar energy reaches every part of the earth 12 hours per day. If we can develop technologies feasible for the exploitation of solar energy, we need not be worried too much about the energy crisis in future. The major problem associated with the exploitation of solar energy is the lack of feasible technologies to convert solar energy into other forms of energy. Since solar energy is available only in day time, it is necessary to ...Download file to see next pagesRead More

Solar energy as an alternative energy source

...Another Energy Source: Solar Energy On Friday 13th, it was the first time for a solar energy powered plane to make its first flight international flight. It showed the potential for pollution free air travel. It took the 13hr flight to land at Brussels from Payerne air field in Western Switzerland. Borshberg, who was the pilot, said that fitting a slow flying plan into a traffic system of commercial air is challenging. The pilot further said that flying from a place to another using the alternative sources of energy that is solar energy is quite symbolic. (uk.news.yahoo.com 2011) Solar energy is more abundant, less exhaustible, and a...

...Engineering and Social Issues Alternative Energy Introduction The global economic crisis is partially attributed to the lack of sustainable energy in the globe. Most of the industries in the global economy use fossil fuels as their sole source of energy. The scarcity of the commodity which has been caused by the depletion of reserves has caused the global prices of oil products to increase. The solution to this problem is alternative energy (LePoire, 2011). Alternative energy incentives The US government should increase the incentives to attract alternative energy investment. Increase in incentives will increase the alternative energy sources which are cheap and sustainable. This will cut down the production cost of goods... which will...

...Advantages and Disadvantages of Wind Energy As the world is beginning to realize the problems of global warming due to pollutions and also the problem of fossil fuel shortages, there has been a growing attention and developing trend for alternative, renewable and more ecologically safer forms of energy source production. The use of wind power is one of the handful alternative options for an alternative energy production. This energy is produced when turbines change the kinetic power of winds into electrical currents. Then a gearbox turns the slow rotor into faster moving gears, which transfer mechanical forces to electricity. Jacobson (2008) even stated that “some...

...Task Energy plays a central role in development. Wind energy is a natural renewable form of energy harnessed to other forms such as electric energy and potential energy. Harnessing of energy is expensive; strict scrutiny needs to establish the cost benefit range. In a small town of Kaplanville of 25,000 people in the US, with the mayor as an instructor, decision to produce wind energy would depend on many factors such as the strength of wing and frequency of the wind. Several advantages are associated with wind energy. To start with, wind energy is a renewable source of...

...Energy The types of energy, the use of energy and insufficient access to energy have far-reaching implications for the economic development of a city. The burning of the hydrocarbon has been a key contributor of the greenhouse gases that cause global warming. In cities where sustainable energy and climate action plan are implemented reduce their vulnerability to energy scarcity and to energy price rises. Cities should specifically consider the needs of users first. The users also should ensure that they reduce their demand on the energy resources. This means that it should be a shared responsibility in...
