Sources of Clean Energy - Essay ExampleSo the point is that the still way to avoid the global force out crisis in future is to fol baseborn the policy of natural recourses frugality and to use renewable sources of energy, such as solar energy, geothermal energy, wind place, water power, and biofuel. So renewable energy is energy derived from resources that are regenerative or for exclusively practical purposes can not be depleted2.Wind - is virtuoso of the renewable energy sources. The wind is considered by experts as one of the most perspective energy sources, assailable to replace not only traditional sources, only if also nuclear power. Production of the electric power by means of wind has a number of advantagesBut as well as in other sources of energy usage, we can find some negative aspects in usage of wind power. The ingrained defect of a wind power is its intermittency. Moreover the usage of wind power whitethorn get going to a kind of environmental pollution, which existence and importance are often undervalued. It is a noise pollution. In Ohio one of the leading American companies has constructed the worlds largest wind power plant with rating power 10 MW. This considerable construction with the general height over hundred meters has worked just for some days and after has been exchange for demolition at the price of 10 dollars per ton. The thing is that the life in radius of several kilometers has scram just impossible. And question is not only in audible noise and vibrations. There is a actually strong infrasonic, low frequency component in this noise. The point is that an infrasound on the frequency of 7 Hz conterminous with an alpha rhythm of a humans brain at sufficient intensity is very harmful. It may cause the strongest health disorders. Moreover the usage of wind turbines may result desertification of the grounds and in this plate animals would have to leave their traditional areas of living. So the biodiversity may be decreased . Solar Power The leading groovy energy source is the solar power. The energy of a solar radiation coming on the bug out of our planet, almost in 40 times exceeds all energy consumed by the mankind. Every second the sunlight gives the Earth 80 thousand billion kilowatt of energy, that in some thousand times more, than all the power stations of the world produce all together.Now mankind use only insignificant fracture of a solar energy, as existing solar batteries have rather low efficiency and are very expensive to produce. However we should not refuse from this practically inexhaustible source of clean energy. concord to the statements of experts, this source could cover all needs of mankind for energy thousand years forward. The solar power is the most powerful and accessible of all kinds of non-traditional, renewable energy sources. Sunlight is not only inexhaustible, but also absolutely clean energy source having enormous energy potential. Nevertheless the usage of solar po wer also has own disadvantages.Solar energy is distributed on the big area, or in other words, has low density. That is why any plant for direct use of solar
