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 ]
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.
The plant caused flooding of over 5,000 km 2 (1,900 sq mi), which damaged the habitats of many [quantify] animals, disrupted caribou migratory routes, and drowned wildlife such as beavers. [21] Furthermore, Innu burial sites and hunting grounds were destroyed, causing irreparable damage to the traditions and livelihoods of the Innu people. [ 22 ]
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 ]
To supply water to Plant 1 and 2, a weir with a height ranging 4–16 ft (1.2–4.9 m) creates a small reservoir. The intake for Plant 1 is located just above the left abutment of the weir. Water from the intake enters a 280 ft (85 m) long and 7 ft (2.1 m) diameter vertical penstock which supplies water to the plant. Plant 1 is located in a ...
Water is required for all life, but since ancient times, mankind has also employed this natural resource for other specifically human productive uses. Millennia ago man learned to navigate on water, learned to dam and divert it for irrigation and build aqueducts and canals to carry it where possible, and learned to convert the power of moving water to mechanical energy to perform work.

The Yacyretá Dam or Jasyretâ-Apipé Hydroelectric Power Station (from Guaraní jasy retã, "land of the moon") is a dam and hydroelectric power plant built over the waterfalls of Jasyretâ-Apipé in the Paraná River, between the Paraguayan City of Ayolas and the Argentine Province of Corrientes.
The arch shape provides extra strength to counteract the force of the water. Arch style dams are generally constructed in narrow canyons. Arch style dams are commonly made from concrete. To ensure the dam's integrity, a solid contact between the bedrock foundation and the dam's concrete base is required. The dome style dam is a type of arch dam.
