Question: Why is hydropower better than coal?

Is Hydro more efficient than coal?

Hydropower is the most energy efficient power generator. Currently, hydropower is capable of converting 90% of the available energy into electricity. This can be compared to the most efficient fossil fuel plants, which are only 60% efficient.

Why is hydropower good for the environment?

Hydropower is better for the environment than other major sources of electrical power, which use fossil fuels. Hydropower plants do not emit the waste heat and gases—common with fossil-fuel driven facilities—which are major contributors to air pollution, global warming and acid rain.

What are the pros of hydropower?
