The current use of fossil fuels as our main energy source has two drawbacks: their inevitable depletion and the pollution associated with combustion. These two drawbacks in addition to the growing concern of global warming has pushed for the development of more sustainable sources of energy, namely solar energy and its derivatives (i.e. wind power). Solar energy is appealing for its potential to meet all our demands, while proving to be a pollution free resource.(Bohn, 2009)

Solar energy originates from the thermonuclear fusion reactions occurring in the sun. Leaving all the byproducts of the reactions behind in the sun, the energy that reaches the Earth is pure radiant energy. This energy represents the entire electromagnetic spectrum, ranging from x-rays to radio waves. Most of the sun’s energy, forty-three percent, is in the form of visible light, which can be harnessed for electrical production. The amount of energy hitting the Earth is incredibly large; by one calculation, a month of sunshine has the equivalent energy of all the planet’s used and unused fossil fuels.(Huang, 2007) However, the nature of solar energy has two disadvantages. The sun does not shine consistently throughout the day due to clouds and other atmospheric factors, which can be problem for constant electricity and heat production. Moreover, solar energy cannot be used for nighttime production. The other shortcoming is that the energy from the sun is a diffuse source, that is, it falls over a wide area. In order to utilize this energy, it must be concentrated into a form and amount we can use, such as heat and electricity. These problems are addressed in the three steps used to harness the sun’s energy: collection, conversion, and stor...

Essay on Solar Power And Its Effects On The Environment

- 1. Introduction Due to the important of energy in the development of economic and prosperity of a country and with the growth of worldwide population and industrialization, the demand of energy has been dramatically increasing. However, the use fossil fuel to produce energy has many negative effects on the environment such as increasing the world’s carbon dioxide and depletion of fossil fuel resources which are serious issues these days. As the result, renewable energy, namely wind, solar, biomass and geothermal energy, has been encouraged by many countries as its sustainable use and not contributing to the world’s carbon dioxide emissions....   [tags: Solar energy, Photovoltaics, Solar power]
