Why is fossil fuels worse then hydroelectric power?

Fossil fuels are worst than hydroelectric power because when they are burnt to harness their energy, they release CO2, a greenhouse gas, this enhances the effects of global warming and as once fossil fuels have been mined and burnt, they are gone and will not reacumilate again for millions of years whereas hydroelectricity doesn't burn any carbon, releasing no CO2 and hydroelectricity's original source of power will never run out, making it much more efficient.


Is hydroelectric power better than fossil fuels?
