Hydropower is one of the oldest renewable energy sources. It is generated when flowing water is channeled through water turbine, which rotates a shaft and then drives an electric generator, converting the motion into electric energy. Its widespread use has made hydro power to become:
- one of the most cost effective ways to generate clean energy with minimum impact to the environment
- mature technology, providing widely and long time proven technical solutions
- in Europe, there are nearly 22.000 small hydro power plants in operation and it is expected that their number will increase to 24.000 by the end of 2020
- small hydro power plants are generally built using simple structures with minimum alteration of the watershed conditions and surrounding areas.
