Water is also heavily used in the energy production process.

Why is Hydro declined?

Hydropower is energy in moving water

Hydroelectricity’s share of total U.S. electricity generation has decreased over time, mainly because of increases in electricity generation from other sources.

Why hydroelectric power is bad?

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.
