The comparison between the Conventional and Non-conventional sources of Energy is mentioned below :............1)Conventional energy, such as thermal powers (from coal, petroleum, and natural gas), hydel power (from high velocity of running water) are tapped and used abundantly at present. Their uses are practiced for a long time. But,in contrast to conventional sources of energy, non-conventional sources of energy (solar energy, tidal energy, geo-thermal energy, wind energy, etc.) are not used frequently and in large scale (commercially). Their uses are comparatively more recent.............
2)Except hydel power, the sources of thermal power i.e. other conventional energies are non-renewable in nature. The enormous reserve of fossil fuels (coal, crude-oil, natural gas, etc.) are fast depleting. But the sources of non-conventional energy are flow-resources. There is no anxiety for their exhaustion.............
3)Except hydel power, the generation of other conventional energy produces air pollution and causes environmental threats. But the generation of non-conventional energy does not produce air pollution...........
4)Except hydel power, the otherconventional energy is costly. But comparatively, the non-conventional energy is much cheaper..........
5)The conventional energy sources contribute greatly to global warming and tend to be very bad for the environment. Hence, energy users are increasingly turning towards non-conventional ..............
