  2. Hydropower - Wikipedia

    en.wikipedia.org/wiki/Hydropower

    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 ]

  3. Hydroelectric power in the United States - Wikipedia

    en.wikipedia.org/wiki/Hydroelectric_power_in_the...

    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.

  4. Hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Hydroelectricity

    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]

  5. List of hydroelectric power station failures - Wikipedia

    Failed in fair weather due to a combination of poor construction, age, and neglect. Caused downstream failure of the Cascade Dam. Destroyed historical Stanley hydro power station and a fish hatchery. Flooded a campground and the town of Estes Park impacting 75% of business activity. $31 million in damages and three lives lost. Three similar ...

  6. Hydroelectric power in India - Wikipedia

    en.wikipedia.org/wiki/Hydroelectric_power_in_India

    The International Hydropower Association estimates that the total hydropower potential in India is 660,000 GWh/year, of which 540,000 GWh/year (79%) is still undeveloped. [15] India ranks as the fourth country in the world by undeveloped hydropower potential, after Russia, China and Canada, and fifth by total potential, surpassed also by Brazil ...

  7. World energy resources - Wikipedia

    en.wikipedia.org/wiki/World_energy_resources

    Renewable energy sources are even larger than the traditional fossil fuels and in theory can easily supply the world's energy needs. 89 PW [32] of solar power falls on the planet's surface. While it is not possible to capture all, or even most, of this energy, capturing less than 0.02% would be enough to meet the current energy needs.

  8. Low-head hydro power - Wikipedia

    en.wikipedia.org/wiki/Low-head_hydro_power

    Low-head pumped seawater storage: Currently at very low TRL levels but in the coming decade these technologies could become part of the energy system. Dynamic tidal power: Another potentially promising type of low-head hydro power is dynamic tidal power, a novel and unapplied method to extract power from tidal movements. Although a dam-like ...

  9. Hydroelectric power in New Zealand - Wikipedia

    en.wikipedia.org/wiki/Hydroelectric_power_in_New...

    This means that maximum storage of energy is 34 days during the peak of winter. If there is an unusual amount of precipitation one year, then there would be a shortfall in energy from the hydro system. In addition, the cost benefit of using hydroelectric power over wind or geothermal energy in New Zealand is highly debated. [1]
