The Tocantins watershed was, historically, an important access point for freshwater amongst the humans and animals living in the region. As a result of construction, however, the water quality of the Tocantins River Basin has been jeopardized due to discharge of industrial effluents, residues of agricultural uses, and untreated sewage disposal.
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 ...
[3] [16] Around 10% of the energy from the station is generated from rainwater; the rest is from the water pumped up from Loch Awe. [ 3 ] The station is capable of generating 440 megawatts (590,000 hp) of electricity from four turbines, two of 100 megawatts (130,000 hp) and two of 120 megawatts (160,000 hp) capacity, after two units were ...
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] A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response ...
Roughly about 10 to 15 percent of California's energy generation is from large hydroelectric generation that is not RPS-eligible. [6] The significant impact of dams on the power sector, water use, river flow, and environmental concerns requires significant policy specific to hydropower.
The Edersee Dam in Hesse, Germany. A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability.
Kielder Water is a large man-made reservoir in Northumberland in North East England.It is the largest artificial lake in the United Kingdom by capacity of water and it is surrounded by Kielder Forest, one of the biggest man-made woodlands in Europe.
