Explanation:

Advantages and Disadvantages of Hydropower

Hydropower offers advantages over other 

energy sources but faces unique 

environmental challenges.

Advantages 

Hydropower is a fueled by water, so it's a 

clean fuel source. Hydropower doesn't 

pollute the air like power plants that burn

fossil fuels, such as coal or natural gas.

Hydropower is a domestic source of 

energy, produced in the United States.

Hydropower relies on the water cycle, which is driven by the sun, thus it's a 

renewable power source.

Hydropower is generally available as 

needed; engineers can control the flow of 

water through the turbines to produce

electricity on demand.

Hydropower plants provide benefits in addition to clean electricity. Impoundment 

hydropower creates reservoirs that offer a variety of recreational opportunities, notably fishing, swimming, and boating. Most hydropower installations are required 

to provide some public access to the reservoir to allow the public to take advantage 

of these opportunities. Other benefits may include water supply and flood control.

Disadvantages 

Fish populations can be impacted if fish cannot migrate upstream past impoundment 

dams to spawning grounds or if they cannot migrate downstream to the ocean. Upstream fish passage can be aided using fish ladders or elevators, or by trapping 

and hauling the fish upstream by truck. Downstream fish passage is aided by

diverting fish from turbine intakes using screens or racks or even underwater lights

and sounds, and by maintaining a minimum spill flow past the turbine.

Hydropower can impact water quality and flow. Hydropower plants can cause low 

dissolved oxygen levels in the water, a problem that is harmful to riparian

(riverbank) habitats and is addressed using various aeration techniques, which 

oxygenate the water. Maintaining minimum flows of water downstream of a 

hydropower installation is also critical for the survival of riparian habitats.

Hydropower plants can be impacted by drought. When water is not available, the 

hydropower plants can't produce electricity.

New hydropower facilities impact the local environment and may compete with other 

uses for the land. Those alternative uses may be more highly valued than electricity

generation. Humans, flora, and fauna may lose their natural habitat.
