Abstract : The consumption of Petro-fuel is increasing day by day with the increasing population. The coal, oil and natural gas, thermal power, firewood (fuel-wood), hydro power, nuclear power; all come under conventional sources of energy and in time to come, can decline, but non-conventional sources of energy includes, solar energy, wind energy, tidal energy, geothermal energy, biomass based energy, petro-plants, biogas, dendrothermal energy etc. Some of the energy sources have been described with their advantages and disadvantages. Each energy source has pros and cons. It is time to have a balance between the demand and production.
Thorium based energy has been established in India because the availability of Uranium is less. In India, in the first phase, pressurized heavy water reactor came into existence, in which Uranium was used; in the second phase India made fast breeder reactor, in which a mixture of Uranium and Plutonium was used; in the third phase thorium based reactor came into existence. Much stress is now being paid in tapping solar energy.
It is estimated that a total of 30 % energy is to be drawn from sun, 30 % from oceanic water, 25 % from biogas and 15 % from other sources.
The mixture of CNG (compressed natural gas and 10 % hydrogen) is likely to be used as fuel at Indian Oil Corporation at Faridabad. The present attempt of the country is to utilize ‘Hydrogen’ as fuel in all car/ Trucks and vehicles, which are either utilizing Petrol or Diesel.
The present attempt should be to find out new sources of energy possibly from hydrogen vis a vis reduce population to consume less energy.
