Solar Energy

[name][professor /instructor][subject][date] : its benefits , technology and cost efficiencyMan has desireed and used push at an increasing rate for his sustenance and well being incessantly since he came on the earth a few billion long time Primitive man required pushing in the beginning in the form of food . With the passage of time , hands have discovered and used different slide fastener resources for a lot of purpose from the discovery of steam engine , to nuclear energy and fossil fuels . In the past few years , it has become obvious that fossil fuel resources are ready depleting and that the fossil fuel era is gradu every(prenominal)y coming to an cease . This is particularly true for oil and natural gas . This is collectible to increasing rate of consumption and growing population that the need for an alternative energy options will be established - and genius of these options is the . is a very pear-shaped , inexhaustible source of energy . The precedent from the sunlight intercepted by the earth is approximately 1 .8 x 1011 MW , which are many thousands of times larger than the picture consumption rate on the earth of all technical energy sources . Thus , in principle , solar energy could supply all the present and future energy inevitably of the world on a continuing basis . This makes it one and only(a) of the nearly promising of the unconventional energy resources . In accessory to its size , solar energy has two other factors in its favor . Firstly , unlike fossil fuels and nuclear power , it is an environmentally clean source of energy Secondly , it is chuck up the sponge and available in adequate quantities in almost all parts of the world where people live . However , at that place are many problems associated with its use . The main problem is that it is a dilute source of energy . Even in the hottest regions the solar radiation flux available rarely exceeds 1 kW /m2 . These are low values from the point of view of scientific utilizations .

Consequently , large collecting areas are required in many applications and these results in excessive costs A blink of an eye problem associated with the use of solar energy is that its availability varies wide with time . The variation in availability occurs daily because of the day-night rhythm method and also seasonally because of the earth s orbit around the sun . Thus , the real challenge in utilizing solar energy as an energy alternative is of an economic nature . genius has to strive for the development of cheaper methods of collection and storage so that the large initial investments required at present in most applications are reduced ADDIN EN .CITE SukhatmeS .br SukhatmeK Sukhatme1996Tata McGraw-Hill (Sukhatme and SukhatmeBenefitsThere are many uses for solar energy . Direct thermal applications involves the direct use of warming plant , resulting form the absorption of solar radiation , for space wakening and cooling of residences and other buildings , to provide hot-water for such buildings , and to provide heat for agricultural , industrial , and other processes that require only unemotional temperatures ADDIN EN .CITE Brown20022 226Charles E BrownWorld Energy...If you want to get a serious essay, order it on our website: Orderessay
