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 ]
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 ...
The amount of hydroelectric power generated is strongly affected by changes in precipitation and surface runoff. [4] Hydroelectric stations exist in at least 34 US states. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which in 2012 was the source of 44% of the nation's hydroelectricity. [5]
Renewable electricity generation by source and country in 2023 [1]. This is a list of countries and dependencies by electricity generation from renewable sources. [1]Renewables accounted for 30% of electric generation in 2023.
This article provides a list of the largest hydroelectric power stations by generating capacity. Only plants with capacity larger than 3,000 MW are listed. The Three Gorges Dam in Hubei, China, has the world's largest instantaneous generating capacity at 22,500 MW of power.
The largest hydroelectric power station is the Three Gorges Dam in China, rated at 22,500 MW in total installed capacity. After passing on 7 December 2007 the 14,000 MW mark of the Itaipu Dam , the facility was ranked as the largest power-generating facility ever built.
From 2008 to 2018, hydropower has generated almost 60% of total electricity production in New Zealand, with 82% generation from renewable resources. Currently, New Zealand has over 100 hydroelectric power plants in use. [15] From the early 1900s to 2010, there has been a plateau in energy growth for hydroelectric power systems.
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
