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 ...
Museum Hydroelectric power plant "Under the Town" in Užice, Serbia, built in 1900 [11] Hydropower has been used since ancient times to grind flour and perform other tasks. In the late 18th century hydraulic power provided the energy source needed for the start of the Industrial Revolution .
In 2020, hydropower supplied 17% of the world's electricity, down from a high of nearly 20% in the mid-to-late 20th century. [80] [81] In conventional hydropower, a reservoir is created behind a dam. Conventional hydropower plants provide a highly flexible, dispatchable electricity supply. They can be combined with wind and solar power to meet ...
However many run-of-the-river hydro power plants are micro hydro or pico hydro plants. Much hydropower is flexible, thus complementing wind and solar, as it not intermittent. [92] In 2021, the world renewable hydropower capacity was 1,360 GW. [73] Only a third of the world's estimated hydroelectric potential of 14,000 TWh/year has been developed.
Bioenergy is a type of renewable energy that is derived from plants and animal waste. [1] The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2] Thus, fossil fuels are not regarded as biomass under this definition.
Angat Dam, a major hydropower facility in the Philippines. Hydropower is one of the main sources of renewable energy in the Philippines. There are hydroelectric plants of both the conventional dam and run-of-the-river types in the country. Of twenty-nine hydroelectric plants, fourteen are conventional dam and fifteen are run-of-the-river systems.
Unlike most renewable sources, biomass (and hydropower) can supply stable base load power generation. [58] Biomass produces CO 2 emissions on combustion, and the issue of whether biomass is carbon neutral is contested. [59] Material directly combusted in cook stoves produces pollutants, leading to severe health and environmental consequences.
Energy development is the field of activities focused on obtaining sources of energy from natural resources. [citation needed] These activities include the production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted.
