benefits of hydroelectricity
Benefits of hydroelectricity
  • Hydroelectric energy is a continuously renewable resource.
  • Hydroelectric energy is non-polluting.

disadvantages of hydroelectricity
Disadvantages of hydroelectricity
  • Environmental Damage- Hydroelectric plants can be disruptive to aquatic ecosystems.
  • Greenhouse Gases- The reservoirs of power plants in some regions may produce amounts of Methane and Carbon Dioxide.
  • Population Relocation- People will need to relocate because of where the plants are built.
  • Dam Failures- While the failures of Dams are Rare they can be very serious.
