What is a hydropower plant?
Water in motion contains energy. And it is this energy that a hydropower plant exploits to produce green electricity. Once precipitation and water vapour from the sea have accumulated in the high-lying reservoirs in the Norwegian fells, the large volumes of water are directed through the power plant’s turbines on the way down the mountain. The water makes the turbine spin, transferring much of the energy from the water to the turbine. The principle is similar to that of a wind turbine. In this case, it is the wind that causes the turbine to spin and produce power.
