Alternate Sources of Energy

Extracts from this document...


ESSAY ON ALTERNATIVE SOURCES OF ENERGY The law of conservation says that energy is neither created nor destroyed. When we use energy, it doesn't disappear. We change it from one form of energy into another. A car engine burns gasoline, converting the chemical energy in gasoline into mechanical energy. Solar cells change radiant energy into electrical energy. Energy changes form, but the total amount of energy in the universe stays the same. Scientists at the Department of Energy think they have discovered a mysterious new form of energy called "dark energy" that is actually causing the universe to grow! The simplest way to define energy is said by: the capacity to do work by moving matter against an opposing force. If neither the table nor pencil moves, no work is done and therefore no energy is transferred. Force and energy are just a physical definition in a model that eases 'understanding' of the world around us. With this model one can define many things like the conservation of energy , transferring of energy ,etc. There are different kinds of energies like kinetic, thermal, heat, electrical, solar, potential and many more. These energies are transferred and obtained from different sources, which are namely classified as renewable and non renewable sources of energy. It is recognized that non-conventional or alternative sources of supply will undoubtedly play an increasing role in development as growth proceeds. ...read more.


Fossil fuels come under non renewable sources of energy because we burn the fossil fuel to obtain coal, oil, natural gas, petrol and etc and one day these resources will get over. Nevertheless, these fossil fuels also cause global warming because of the increasing soil and air pollution on burning. Take for example the case of our city Power Station which runs on coal. A fuel that is obtained from wood, by chopping tress and leads to deforestation. This fuel is also difficult and hence expensive to transport. Now burning of coal also leads to air and land pollution, which leads to major problems to the neighboring residences who have to bare the coal emissions on their utensils, which are used for cooking and most of all the emissions lead to hazardous health problems such as lung problems, asthma, eyes burning, stomach pain, etc. Nevertheless, this is a huge problem in society to me because it is doing injustice to the residents who are equal members of the society and they too deserve a clean and fresh environment to live in and grow healthily. Therefore, we as a young generation are responsible ones to bring about a change in this issue because we too are going to face the issue more dangerously in the future. Hence, I believe that there is a huge need to change the materials used to produce electricity in our city and many more cities in the world who are facing such an issue ...read more.


Nevertheless, the energy infrastructure in different parts of the country should be based on the specific energy resources available in that region, so as to reduce transport bottlenecks. And last but not the least, morally energy conservation can start from home. We should start growing more trees, walk short distances, instead of using your vehicle, switch of your engine at the signal, encourage use of solar energy to power your houses and other devices, use battery cars, save electricity by using it efficiently and not keeping devices on when not needed. Also to use more of public transport and incorporate carpools to save on fuel and cause less pollution to the environment. Stop the open burning of leaves and thrash. Rather decompose the material so that the energy can be passed on further. Use of cycles should be encouraged and a separate lane for bicyclists should be made by the government to support this movement. And as Gandhiji said "Be the change you want to see", so hence being a responsible citizen of the country I shall start sowing the seeds for using alternative sources of energy so that the seeds can then grow into plants and blossom as flowers and ripe fruits instead of seeing a dead land in front of my own eyes and bare the view for my and my children's future. So I am going to start saving our nature and not wait for anyone else to do it, but to start today from me to spread the message further to my city, country, continent and to the world at large. ...read more.
