## What are Fossil Fuels

Fossil fuels are derived from buried dead plants and animals which have been underground for millions of years. The fuel is energy that was released in combustion or burning of these organisms. Fossil fuels include petroleum, coal, and natural gas. Kerosene and propane are derivatives of fossil fuel.

This fuel takes years to form in the earth. However, it is being depleted quickly, faster than it can form. This is the main reason fossil fuels are classified as a non-renewable resource

Fossil fuels are the main energy sources in the world. They supply about 80 percent of the world’s energy. Fossil fuels provide electricity, heat, and transportation. The energy generated are used to create a huge range of products from plastics to steel.
