Coal and Petroleum are called Fossil Fuels.  Coal and petroleum were formed from the degradation of bio-mass millions of years ago and hence these are resources that will be exhausted in the future. These are the main energy resources for a human.

Scientists are working on developing some alternate energy sources so that dependency on coal and petroleum can be reduced.

Some examples are given below:

1. Solar energy is being used to produce electricity at many places. Although the technologies for solar energy are still costly future prospects look bright.
2. A fuel cell is another development which may help in replacing the internal combustion engines from automobiles.
3. Hydrogen is being used as fuel in buses and cars in many countries. Hydrogen; when used as a fuel produces water as a byproduct. Thus, hydrogen can be an environment-friendly fuel.
