The fossil fuels such as coal, oil and natural gas meet most of the energy needs of the world today. But what will happen when the reserves of these non-renewable sources of energy get completely exhausted? We also need to pay attention to the damaging effects of fossil fuels on the environment.
The solution must lie in switching to alternative sources of energy and environment-friendly natural fuels. There are several alternative and renewable sources of energy which are not only environment friendly but can also be available in abundance. Water, wind, sunlight, geothermal, sea waves, hydrogen and biomass are some such possible sources of energy.
In addition to the renewability, there are other reasons why we should look to switching over to such sources.
Fortunately, there are many means of harnessing renewable sources of energy which have less damaging effects on our environment.
