Solar Energy , an Alternative to Fossil Energy (Oil

Today ecological sustainability is the greatest concern for all the humankind . Greenhouse effect , an inevitable consequence of the enhanced Greenhouse gases , threatens the very existence of flora , fauna and human race . Greenhouses gases are carbon dioxide , nitrous oxide , and methane As a result of Greenhouse effect , the temperature of the Earth is rising , and even small extra warming will damage the global ecosystem The only way to stop the global warming is to reduce the pollution . The pollution comes largely from energy industry , and [banner_entry_middle]

there is a clear and consistent need to investigate and utilize clean sources of power

Several decades ago scientists believed that nuclear energy can fully supply households and industry . But after the awful catastrophe in Chernobyl and Three Mile Island , the myth of a peaceful atom disappeared . Nuclear energy is not safe enough to be put in everyday use , so the scientific community has long been in search of brand-new and powerful source of energy . This problem is closely connected o another burning question . Natural resources of our planet are being quickly exhausted . As analysts predict , we will feel great shortage of natural resources as far as the middle of the 21st century . So great amount of research concerning alternative or renewable sources of energy , is carried out

Renewable sources of energy are solar power , wind energy , biomass geothermal steam , and hydroelectric sources of power . People started to investigate solar energy long ago some argue that even ancient Greeks used it for heating . But the scientific study of this phenomenon started not so long ago , but the perspectives solar energy opens are breathtaking

I ‘m going to numerate and compare the benefits of solar energy and fossil energy and account for the rational use of each

The benefits of fossil energy are its inexpensive rice and relatively easy production . Oil is the traditional source of power and the economy is almost fossil energy nowadays , and infrastructure in the field of fossil energy is highly developed . Governments state that proper control over environmental impact of fossil combustion can eliminate any danger to the environment . Those who lobby further use of fossil energy state that solar energy plants are expensive , complex to construct and hardly effective . In the following paragraphs I ‘m going to prove the opposite

Solar energy stands for three S : Safety , Stability , and Sustainability . The benefits of solar power are numerous and significant

First of all , solar energy is virtually inexhaustible . Humanity can utilize energy derived from Sun as long as it shines . There is no fear of running out of it

Second benefit of solar power is that it ‘s regenerative . Fossil sources of energy are not considered renewable . It takes centuries and centuries while fossils are formed

Solar power plants have low operative cost . They need few supervision and control

Another benefit of solar energy is that it ‘s decentralized . Solar energy can be obtained in every place on the planet . Oil and gas concentrate… [banner_entry_footer]
