Question

What are fossil fuels? Discuss why they are an important source of energy for us today.

Answer 1

Coal, petroleum and natural gas are called fossil fuels, as they are naturally formed from the remains of organisms. Fossil fuels are concentrated stores of energy and give off heat and light on burning. The heat can be used to cook food or run engines (such as automobile engines). They can also be used to generate electricity in powerhouses (the most common fuel in many powerhouses is coal). Thus, fossil fuels are an important source of energy for us today.
