"Roll On, Columbia, Roll On" was part of the Columbia River Ballads, a set of twenty-six songs written by Guthrie as part of a commission by the Bonneville Power Administration (BPA), the federal agency created to sell and distribute power from the river's federal hydroelectric facilities (primarily Bonneville Dam and Grand Coulee Dam).
Hydropower is a flexible source of electricity since stations can be ramped up and down very quickly to adapt to changing energy demands. [31] Hydro turbines have a start-up time of the order of a few minutes. [37] Although battery power is quicker its capacity is tiny compared to hydro. [2]
The Hoover Dam, when completed in 1936, was both the world's largest electric-power generating station and the world's largest concrete structure. Hoover Dam power station Hydroelectricity is, as of 2019, the second-largest renewable source of energy in both generation and nominal capacity (behind wind power ) in the United States. [ 1 ]
Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. [1] Hydropower is a method of sustainable energy production.
A dam may create a reservoir hundreds of kilometres long, but in run-of-the-river the head is usually delivered by a canal, pipe or tunnel constructed upstream of the power house. The cost of upstream construction makes a steep drop desirable, such as falls or rapids.
The Three Gorges (22,500 MW - 32 × 700 MW and 2 × 50 MW) is operated jointly with the much smaller Gezhouba Dam (2,715 MW), the total generating capacity of this two-dam complex is 25,215 MW. The Itaipu on the Brazil–Paraguay border has 20 generator units with overall 14,000 MW of installed capacity, however the maximum number of generating ...

This is a list of operational hydroelectric power stations in Canada with a current nameplate capacity of at least 100 MW. The Sir Adam Beck I Hydroelectric Generating Station in Ontario was the first hydroelectric power station in Canada to have a capacity of at least 100 MW upon completion in 1922.
