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. The word energy is taken from the Greeks and means "the work within" and nearly all energy originally came from the sun. The main type of energy used in the world is fossil fuel. Fossil fuels are called non-renewable because they are the remains of plants and small dead animals, which have been compressed. This means it takes a very long time to produce coal, oil or any other fossil fuel. For as long as 3,000 years ago coal was being used for fuel and so soon became one of the main energy sources used around the world. However in the 1950s wood became the most popular fuel used in homes. Then in 1709 an English Iron-Maker called Abraham Darby invented a process, which used coke as a fuel in blast furnaces, this process is now known
Some renewable energy sources, which have been discovered, are Bio-fuels, Nuclear fuels, solar power and wind power. Basic nuclear fuel is the heavy, silvery-white metal called Uranium. This naturally gives off radiation, which consists of invisible bits of atoms called alpha particles. Nuclear fuel is used in electricity-generating nuclear power stations. The first product made from crude oil was Kerosene, which is used in Lamps. The question the world needs to ask is, what renewable source is going to be the best? In order to help decide this question I am going to explain a bit about Bio-fuels, Nuclear power, solar power and wind power. Biology is the scientific study of living things. In 1859 the oil industry was born. 500 Million cars around the world use petrol as their source of energy. Since these times however, the world has begun to realise that we must start looking elsewhere for energy. Today there is a massive demand for petrol. The other power sources however are very clean and although expensive at first very efficient. One drawback to this energy source is, wind generators take up a very large area. Bio-fuel is a fuel, which comes from living things or more correctly from recently dead ones.
