energy
The first question, which I must ask in order to write this essay, is, what is energy? Energy gives us the ability to do thing. Everything in the world needs a supply of energy, and so energy is used to make things work.

fossil fuels and alternative energy sources
"Shifting Power" Since the beginning of industry humans have been in search of fuel to power machines and generate energy. Fossil fuels, such as crude oil and coal, discovered beneath the Earth"s surface were found to be an excellent source of fuel. These fossil fuels are burnt in order to generate the energy required to complete various tasks. However, we are now realizing the problems that are created by using fossil fuels to generate energy. These problems are so great that they will fo ... When the worlds supply of fossil fuels runs out there is no way to replenish this non-renewable resource and the world will be forced to find an alternative energy source. ... There are a number of renewable energy sources available to replace the problematic fossil fuels. "Renewable energy is a term used to describe energy that comes from sources which can be regenerated, and are, therefore, virtually unlimited" (Information 136).

Fossil Fuels And Alternative Sources
Debate Topic: Fossil Fuels and Alternative Sources Most people in this world but especially in the U.S. think that fossil fuels are never ending. However, they are wrong and completely take them for granted. Therefore, if they do not try to use and find other sources for energy soon then fossil fuels will become extent.

Impact of Tyres on Environment
¤ THE IMPACT OF TYRES ON THE ENVIRONMENT Ø Tyres play a very significant role in today"s world. Life is not steady today. We highly depend on tyres for our daily needs. We use them in traveling from one place to another and also in carrying goods from one place to another by motor vehicle. It"s very hard to imagine a life without tyres nowadays. The demand for tyres is going on increasing at a very high rate because of the increasing demand of vehicles. There are more than 121 million of tyre ... ¤ Using Tyres Ø Energy Use – A very huge amount of renewable as well as non-renewable energy source is consumed manufacturing each tyre.
