Hydropower has many advantages. It has near-zero emissions of greenhouse gases, while providing a reliable electricity supply at a competitive price. Hydropower is renewable, because the water that is utilized by the power plant is not consumed, but constantly returned in the form of precipitation.
All electricity and energy production impacts the environment. When it comes to hydropower, powerplants and dams involve an encroachment on the environment that changes the conditions of life in and adjacent to watercourses.
In the Swedish electricity system, hydropower is currently Sweden’s largest source of renewable energy. Together with nuclear power, hydropower is the foundation of the Swedish electricity system.
