Some hydropower facilities can quickly go from zero power to maximum output. Because hydropower plants can generate power to the grid immediately, they provide essential backup power during major electricity outages or disruptions.
Hydropower provides benefits beyond electricity generation by providing flood control, irrigation support, and clean drinking water. Hydropower is affordable. Hydropower provides low-cost electricity and durability over time compared to other sources of energy. Construction costs can even be mitigated by using preexisting structures such as bridges, tunnels, and dams.
Hydropower compliments other renewable energy sources. Technologies like pumped storage hydropower PSH store energy to use in tandem with renewables such as wind and solar power when demand is high. Hydropower News.
Also called hydroelectric energy or hydroelectric power.

However, over time, there has been a shift in demand for cheaper and cleaner fuel options, such as the nonrenewable energy source of natural gas, and renewable options like solar power and wind energy. Each energy resource has its advantages and disadvantages. Explore nonrenewable and renewable options with this collection on energy resources. Hydroelectric energy is power made by moving water. Renewable energy comes from sources that will not be used up in our lifetimes, such as the sun and wind.
Renewable resources are an energy source that cannot be depleted and are able to supply a continuous source of clean energy.

Most dams were constructed for irrigation and flood control and do not have hydroelectricity generators.
Department of Energy estimated that in , non-powered dams in the United States had a total of 12, MW of potential hydropower capacity.
