Transcript

  • 1. Nodirbek MaksudovEnvironmental Science
  • 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. 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.  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.  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.
  • 6. Grand Coulee Dam, located inWashington StateChief Joseph Dam, located inWashington StateRobert Moses NiagaraHydroelectric Power Station,New YorkBath County Pumped StorageStation, VirginiaHoover Dam, between Arizonaand NevadaThe Dalles Dam, Oregon
