No because hydroelectricity is renewable (meaning that it isn't in a limited supply). Gravity from the earth, sun, and moon cause rivers to flow and since gravity will never end, rivers will always run and be available for the making of hydroelectricity.

Rivers flow all the time (not including times of severe drought) so hydroelectric power plants are able to operate all the time.
Hydroelectricity is reliable because it's about 90% efficient and converts 90% of the available energy to electricity. There is a low failure rate and a quick start and shutdown. Another reason why hydroelectricity is reliable is because it is useful as long as there is water and there will always be water.
The cost of production of electricity from a thermal power plant is more than that of the hydroelectricity so the later is more used if both the source are available.
Hydroelectricity does not contribute to global warming.
