Find out the present sources of energy that are used by the people in India. What could be the other possibilities fifty years from now?
Share
The present sources of energy utilised by the people of India are electricity, coal, crude oil, cow dung and solar energy. Currently the consumption of energy in India is too high in comparison to its production and reserves. India’s known reserves of oil would last about 30-40 years only and it is necessary to use them wisely. Therefore, other possibilities fifty years from now could include ethanol, bio-diesel, nuclear energy and better utilisation of wind energy, solar energy, geothermal energy, hydrogen energy, tidal energy, wave energy, hydroelectric energy and biomass energy especially with the danger of oil resources running out.
