Hydropower

Hydropower

  • the production of power through use of the gravitational force of falling or flowing water.

  • most widely used form of renewable energy.

  • produces no direct waste, and has a considerably lower output level of the greenhouse gas, carbon dioxide, than fossil fuel powered energy plants.


Hydro electricity

Hydro-electricity

  • 675,000 MW of hydro-electricity

  • approximately 20% of the world’s electricity

  • accounting for about 88% of electricity from renewable sources.


Itaipu power plant

Itaipu power plant

  • largest hydroelectric power plant in the world

  • located between Brazil and Paraguay.

  • can generate 12,600 MW of power.

  • height of the dam reaches 196 meter and the length 7.76 km.

  • lake created by the project spreads over 1,350 sq. km and contains 29 billion tons of water.

  • cost of the project stands at US$20 billion.


Hydropower prospects in bangladesh

Hydropower prospects in Bangladesh

  • flat terrain - limited potential

  • the rivers in the CHT hold such potentials.

  • Kaptai on Karnafuli river generating 218 MW of power.

  • other potential rivers are Matamuhuri and Sangu.
