"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).
The Song Loulou Power Station is a hydroelectric power plant of the Sanaga River in Cameroon. It has a power generating capacity of 384 megawatts (515,000 hp), enough to power over 257,100 homes. The Song Loulou power station is built upstream of another power station; the Edea power station.
Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power or water energy, 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 ...
By 2016 the dam accounted for 6% of Vietnam's total electricity output. Each year approximately 10 billion kWh of electricity is generated by the dam, providing around half of the government revenue of Hòa Bình Province. [8] Since the dam went operational, as of 2021 it had produced a cumulative 230 billion kWh of electricity. [2]
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 can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. [2]
By damming a river, the head is available to generate power at the face of the dam. 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 ...
The Three Gorges Dam in Hubei, China, has the world's largest instantaneous generating capacity at 22,500 MW of power. In second place is the Baihetan Dam, also in China, with a capacity of 16,000 MW. The Itaipu Dam in Paraguay and Brazil is the third largest with 14,000 MW of power.
The most visible part of Thomson Dam is the primary structure straddling the Saint Louis River channel near Minnesota State Highway 210. However, the Thomson Project is actually composed of multiple dams and control structures, several of which have been rebuilt and merged over the years.
