A substance that produces chemical or nuclear energy when it comes in contact with other substances is called fuel. This energy is used as it is or is further converted to mechanical energy and is put to use in different ways. Some of the common tasks carried out with the help of different fuels include running vehicles, operating machinery, cooking, ironing and warming.
Chemical fuels have broadly been classified into three categories – Solid fuel, Liquid fuel and Gaseous fuel. Solid fuels include wood, cow dung, charcoal and coke to name a few. Liquid fuels include petroleum which is processed to form various varieties of liquid fuels such diesel, naphtha, kerosene, etc. Natural gases come under the category of gaseous fuels. These are processed and converted into CNG, blast furnace gas, methane and coal gas for various purposes. Nuclear fuels on the other hand are divided into two categories – Fission and Fusion. Each of these fuels has its own unique utility. We use most of these to carry out our day to day tasks.
Fuels are fast depleting from the surface of the earth. This is because their demand is growing at a rapid speed whereas its supply is limited. We must use these substances wisely so that they do not get exhausted.

Whether you are making use of renewable fuels or non-renewable fuels, you must be cautious about the amount you use. Never misuse these valuable resources. Not only because we need to save these for our future generations but also because using too much of these is not good for the environment which ultimately impacts our health. Most of these fuels, especially the non-renewable ones, are adding to the pollution on earth. Hence, to make our planet a better place to live, we must restrict the use of fuel.
