Alternative Sources of Energy: Geothermal Power and Solar power

Its a well-known fact that the world is dependent on fossil fuels. But how dependent? A survey shows that some 95% of our efficacy, and specifically around 66% of the worlds electrical power, is provided by oil, congenital gas, and coal.(1) Transportation and petrochemical industries argon different examples of argonas where oil is used, objet dart natural gas is mainly used for heat animation systems and as fuel in engines and power stations. As for coal, it is used for producing act and melting minerals such as iron; but practically importantly, it takes the start place in generating electricity, as it provides nearly 60% of the worlds demands.(12) Oil, gas, and coal are expected to run out in more or less 30, 70, and 250 years, respectively.(4) As a result, we are very likely to face serious problems in transportation, alter systems, supply of electricity, functionality of factories and power stations, as well as galore(postnominal) other problems. Meanwhile, we a re facing serious environmental consequences. Since importunate fossil fuels, especially coal, produces carbon dioxide, the earths temperature has been rising 2ºC annually.(12) This has in like manner resulted in geographical changes. In Alaska, for example, more than 300m of a plentifulness has melted.(6) Similarly, more sulphur dioxide has caused more acid rain, which first appeared in Manchester just after the industrial revolution.(1) Whats more, the world has enter more than 100 natural disasters in less than a ten-spot since 2000.

(5) Our planet will not stand this for dour if we strain relying on fossil fuels, and yet we cant function without them. For t! his reason, pick energy sources should be found. I would like to present cardinal renewable energy sources. Let us begin by feel at geothermal power. The term geothermal comes from two Hellenic words that mean Earth heating.(2) This variant of energy has... Wonderful writing! It briefly shows how geothermal & solar powers work. It also provides good examples and statistics. Well done!! If you want to grind a full essay, order it on our website: OrderCustomPaper.com
