Sources of Clean Energy - Essay ExampleSo the point is that the completely way to avoid the global proponent crisis in future is to fol clinical depression the policy of natural recourses saving and to use renewable semens of energy, such as solar energy, geothermal energy, wind power, water power, and biofuel. So renewable energy is energy derived from resources that are regenerative or for all practical purposes can not be depleted2.Wind - is sensation of the renewable energy sources. The wind is considered by experts as one of the most perspective energy sources, capable to replace not only traditional sources, moreover 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 essential defect of a wind power is its intermittency. still the usage of wind power whitethorn lead 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 massive construction with the general height over coulomb meters has worked just for some days and after has been sold for demolition at the price of 10 dollars per ton. The thing is that the life in radius of several kilometers has belong just impossible. And question is not only in audible noise and vibrations. There is a very 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 whitethorn cause the strongest health disorders. Moreover the usage of wind turbines may result desertification of the grounds and in this case animals would have to leave their traditional areas of living. So the biodiversity may be decreased. Solar Power The leading clean energy source is the solar power. The energy of a solar radiation coming on the rise up of our planet, almost in 40 times exceeds all energy consumed by the mankind. Every second the Sun 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 tell apart of a solar energy, as existing solar batteries have rather low efficiency and are very expensive to produce. However we should not go down from this practically inexhaustible source of clean energy. According 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 power also has own dis advantages.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
