How hydropower works film

 

Hydropower Scheme
In some river systems, such as the Devoll river, a number of power stations are positioned in a scheme, so that the water’s energy can be exploited several times before it finally flows out into the sea. By storing water, hydropower reservoirs can reduce our vulnerability to floods and droughts.

1. The water is stored in reservoirs. The level of water can be regulated by means of dams. This makes it possible to store the water until it is needed for power generation.
2. Water can be transferred between the reservoirs via tunnels or natural rivers.
3. The water is transferred to an intake, which feeds the power station.
4. Inside the power station, the running water spins the turbine and a generator turns the energy of the water into electricity.
5. After production, the energy passes through the transformer where it is stepped up to high voltage. Then it is sent onto the power grid. 

Hydropower Facts

  • Hydropower uses the Earth's water cycle to generate electricity. The kinetic energy of flowing water can be converted into electricity
  • Hydropower is a clean and renewable energy source that doesn't pollute the environment
  • Hydropower is the most significant renewable energy source
  • Hydropower is a very efficient energy source because turbines can achieve efficiency up to approx. 95%
  • Hydropower today provides approx. 1/6 of the world's electricity
  • Approx. 95% of Albania’s energy supply is generated with hydropower
  • Hydropower has the lowest production cost among the renewable energy sources
  • Hydropower can be used anywhere in the world where there is flowing water
