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
• 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
•
•
•
•
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
• 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.
