Hydroelectric power is one of the most abundant and useful renewable sources of energy, but there are environmental impacts. A hydroelectric dam requires a reservoir of water behind it; the lake that is formed when the dam is put in place can flood otherwise useful land. Large dams also prevent fish from moving freely about the river, which can impact the ability of some species to spawn, such as salmon.

What is the difference between hydroelectric energy and solar energy?

Solar energy is generated using solar panels that face the sun and gather the energy. Hydroelectric energy is generated by rushing water. The intense pressure creates a large amount of energy. Basically, solar energy uses the sun, and hydroelectric energy uses water.

Does hydroelectric energy come from the sun?

Technically, hydroelectric energy ultimately comes from the sun. This is because the sun's energy heats up water, moving water through the water cycle. Hydroelectric energy is generated by harnessing the power created by the movement of this water.
