Non renewable energy refers to a natural resource that cannot be made or grown or even consumed at a rate that can sustain it. When it is used once, it is finished completely and cannot be used again. The reason it is termed as being non-renewable. Such resources are found in a fixed level and are used much quickly than how nature can make them. Examples are fossil fuels like coal, petroleum and gas and nuclear power like uranium. On the other hand, resources that can be used again such as timber or metals are known as renewable resources.
Fossil fuels like petroleum, coal and gas usually form over such a long time and take many years to be made. Such fuels once used cannot be replaced quickly as compared to the rate in which they are being used. Consequently, what this will lead to is that natural resources will become too expensive to obtain and therefore people will have to find alternative sources of energy. At the moment the crucial energy source that is used by human beings is fossil fuel through petroleum, coal and gas. It has been in use since the 17th century when it was first used for the internal combustion engine. Its demand is still high with the advancing technology requiring more of it.
Radioactive fuel is the main source of energy that is used in nuclear technology. Uranium which is a mineral is found in its ore in the earth at very low levels currently and is also mined in 19 countries in the world. Uranium ore is what is mainly used to make plutonium. Nuclear fuel is the main material used for the manufacture of nuclear weapons. It is also the main component that is used to create electricity. It produces approximately 6% of the world’s energy and approximately 13-14% of the electricity used in the world. However nuclear energy is very volatile and contaminating and its radio-active waste is very harmful to the body. It is found to be a high source of cancer in the body.
Such kinds of energy have shown to be quite effective in the industrial sector with majority of them being used in manufacture of different types of products. However care should be taken to ensure that these sources of energy are used in such a way that is efficient.
