Hydropower is turning the kinetic energy into a form useful to people. Water power is a domestic, renewable and it makes no exhausts. Water power is cheap because it is long-lasting.
Water turbine was invented in 19th century. In the 20th century the most of Finland’s waterfalls were harnessed into production of electricity. The first water power plant in Finland was built in 1891 in Tampere. One of the biggest water power plants is the Imatrankoski water power plant. In the 1950-60s even 90% from the needed electricity in Finland was produced with waterpower. In 2012 Finland had over 220 hydropower plants.
Hydropower plant’s action is based on that a river’s streaming water has potential energy before reaching a waterfall. the energy coming from a waterfall is turned into kinetic energy. Stronger the river’s stream, more kinetic energy we get. When the water streams down the waterfall it proceeds into a turbine.
