Some dams only generate power and serve no other purpose, but in many places large reservoirs are needed for flood control and/or irrigation, adding a hydroelectric portion is a common way to pay for a new reservoir. Flood control protects life/property and irrigation supports increased agriculture.
The Crystal River Energy Complex consists of seven power-generating plants on a 4,700-acre (1,900 ha) site near the mouth of the Crystal River in Citrus County, Florida. Crystal River 1, 2, 4, and 5 are fossil fuel power plants. Crystal River 3 was previously the sole nuclear power plant on the site (1977-2013). The Crystal River Combined Cycle ...
[34] [page needed] At a dam in Brazil, where the flooded basin is wide and the biomass volume is high the methane produced results in a pollution potential 3.5 times more than an oil-fired power plant would be. [35] A theoretical study has indicated that globally hydroelectric reservoirs may emit 104 million metric tonnes of methane gas ...
In 2021, hydroelectric power produced 31.5% of the total renewable electricity, and 6.3% of the total U.S. electricity. [2] According to the International Hydropower Association, the United States is the 3rd largest producer of hydroelectric power in the world in 2021 after Brazil and China. [3] Total installed capacity for 2020 was 102.8 GW.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity , almost 4,210 TWh in 2023, [ 1 ] which is more than all other renewable sources combined and also more than nuclear power . [ 2 ]
Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively ...
In the late 1960s, the Florida Department of Air and Water Pollution Control was created under Governor Claude R. Kirk, Jr. Most staff were being taken from the Bureau of Sanitary Engineering of the state Department of Health. The name of the new agency was simplified to the Florida Department of Pollution Control. [citation needed]
The Federal Power Act created the Federal Energy Regulatory Commission (FERC) as the licensing authority for hydroelectric power. Over time, FERC's task list grew to include conservation and protection of natural waterways and the wildlife within them. The Federal Power Act was the first major regulatory legislation for hydropower.
