Fossil Fuel

Fossil Fuels:

Fuels that were formed from the remains of dead plants and animals are called fossil fuels. These were produced by complex processes with the help of a series of natural events over millions of years. The most widely used fossil fuels are coal, petroleum and natural gas. You know that plants trap solar energy in the form of food, and animals get energy when they eat the plants. Since fossil fuels came from plants and animals, their ultimate source of energy is the sun.

We get a number of different fuels from coal and petroleum. For example, we get petrol, diesel, kerosene and LPG from petroleum, and coke and natural gas from coal. When burnt in air, fossil fuels give off heat, which is used for various purposes-from cooking to generating electricity. However, these fuels are nonrenewable. and their reserves are running out. Unfortunately, we cannot repeat the events that led to their formation.
