Why is hydroelectricity good source of energy?

There are many reasons why using more hydroelectric power or hydroelectricity is good like for instance the fact that hydroelectric power is clean, renewable source of energy that doesn't contribute to global warming and climate change like fossil fuels such as oil do.

Hydroelectric power plants ensure  reliable delivery of electricity by enabling the stable production of electricity which isn't the case with other renewable energy sources such as solar and wind (the intermittency of solar and wind energy).

Hydroelectric power plants have very long history of use, and generate the largest share of renewable energy in the world, much more than solar, wind and geothermal energy do.

The lake that forms as a result of building hydroelectric power plant doesn't have to be solely used for purpose of generating electricity but can also be used for irrigation and recreational tourism in form of water sports, fishing, swimming, and boating.

The force of moving water generates electricity.

Once constructed hydroelectric power plants have very long lifespan and relatively low maintenance.

By using more hydroelectricity instead of getting our electricity from fossil fuels we would also improve our energy security and energy independence as this would lead to reduced foreign fossil fuel import.

Hydroelectric power projects doesn't have to be necessarily large ones, in fact there has been a significant increase in popularity of small and micro hydro systems.

Hydropower is very efficient source of energy, meaning that very little of available energy gets wasted in the process.

Hydropower has excellent potential. The U.S. Department of Energy (DOE) recently said that available water energy resources could satisfy 15% of U.S. energy demand by 2030. There are approximately at least 54,000 non-powered dams in the United States that could be used to generate electricity.
