why do we need alternative sources of energy ??/
Alternate systems of energy are necessary because:
- The mainstream fossil fuels like coal and petroleum are non renewable so their reserves are ending fast. Soon all the existing reserves will be finished in about next 50 years.
- The burning of fossil fuels is polluting the environment.
- The CO2 obtained from burning fossil fuels is leading to greenhouse effect leading to global warming.
- Alternate energies do not cause such pollution and are renewable.
