what are renewable & non-renewable source of energy
Non-renewable energy sources like coal, oil, natural gas are those sources that cannot be reproduced, are limited and will be expired in the years to come. This results in depletion of these energy reserves.
Renewable resources such as the movement of water (hydropower, tidal power and wave power), wind and radiant energy from geothermal heat (used for geothermal power) and solar energy (used for solar power) are practically infinite and cannot be depleted, unlike their non-renewable counterparts, which are likely to run out if not used sparingly.
