Hydroelectricity

  1. 1. Nodirbek MaksudovEnvironmental Science
  2. 2. Hydroelectric power, orhydroelectricity, is electrical powerthat is generated through the kineticenergy of flowing water.About 20% of the worlds electricalenergy requirement is fulfilled byhydroelectric power. It is the mostwidely implemented renewableenergy generation technology, withthe highest market share in the world.
  3. 3. The dam, lake or reservoir storeswaterThe water goes through thePenstock to the turbinesThe turbine (propelled by theforce of the water being carried in)turns the generator to produce theelectricityThis electricity is then sentthrough power lines
  4. 4.  Electricity produced through thehydroelectric energy generation methodis produced without any pollution orharmful environmental effects. Neitherare any dangerous greenhouse gasesemitted. Hydroelectric power plants generaterenewable energy. This means that thesource of the energy wont run outanytime soon. Since running water,unlike fossil fuels, will always remain aconstant, hydroelectric energy has noexpiry date.
  5. 5.  Hydroelectric energy plants alter theenvironment in their surroundings to agreat extent. River ecosystems arebased on the continual flow of water.The backwaters from reservoirsseverely change the conditions, turningit into a swampy, lake biome. The flood from the backwater alsoforces human settlements, sometimesseveral villages, to relocate.
