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.
There were two prime results of Pelton's design: it consolidated the introduction of a new physical science into the ancient human quest to develop hydropower, i.e., the science of the impulse turbine as opposed to the reaction turbine; and it revolutionized the use of turbines adapted for high head (i.e., elevation energy) sites.
In October 2014, the Electricity Regulatory Authority (ERA), licensed nine new renewable energy projects, including Siti I Hydroelectric Power Station. The power complex consists of two run of river generation units; Siti I with capacity of 5 Megawatts and Siti II, with capacity of 16.5 Megawatts.
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 ]
Renewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries. [ 194 ]
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] In 2021, hydroelectric power produced 31.5% of the total renewable electricity, and 6.3% of the total U.S. electricity. [2]

The terms kinetic energy and work in their present scientific meanings date back to the mid-19th century. Early understandings of these ideas can be attributed to Thomas Young, who in his 1802 lecture to the Royal Society, was the first to use the term energy to refer to kinetic energy in its modern sense, instead of vis viva.
