The transformation of energy from one form to another playsthe most important role in our everyday work. The development of science andcivilization is closely linked to the availability of energy in useful forms.
Earth would be crippled without energy. We use different forms of energy hereon earth, but all of them directly or indirectly originate with the sun. Everymorning it rises bringing light and heat to the earth and sets in the evening.The energy coming from the sun is known as solar energy. Weget it in the form of light and heat. By the process of photosynthesis plantsconverts it into chemical energy which remains kept in the food. That is whylife on earth still exists.
Solar energy is produced by collecting sunlight andtransforming it into other energy forms like electrical or mechanical energy.The sun sends more energy to the earth in only one hour than the whole planetneeds in a year. So the scientists are trying to improve the process ofcapturing it. Photovoltaic cells, also known as solar cells converts sunlightinto electricity. Then this electricity can be converted to other energies veryeasily. The benefits of solar power beyond description.
The lifespanof the sun is of billions of years. So as long as the sun exists, solar powerexists. It is the most available renewable energy in the world. On addition, itcauses no harm to the environment since it is pollution-less. In rural areasmany families use this energy for their household purposes.
Even in SajekValley, a renowned tourist spot of Bangladesh is totally dependent on theenergy coming from the sun. The uses of solar power are increasing & the process ofusing it at its best is developing day by day. Other sources of energy in the worldmight fade away, but solar energy is everlasting. So the future of the worldslightly relies on how we use this unbounded energy for the sake of mankind.
