What are the conventional and non-conventional sources of energy? Give examples.

NON CONVENTIONAL =

Energy generated by using wind, tides, solar geothermal heat and biomass including farm and animal waste as well as human excreta is known as non-conventional energy. All these sources are renewable or inexhaustible and do not cause environment pollution. More over they do not require heavy expenditure.

CONVENTIONAL=

Conventional energy means the energy source which is obtained from fixed reserves in nature like oil, gas and coal. In other words conventional energy is also termed as non-renewable energy sources, or fossil fuels.

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
