Switzerland and the Scandinavian countries obtain much of power they need from?

Switzerland and the Scandinavian countries obtain much of their power from hydropower. Hydropower is a renewable energy source that uses the energy of flowing water to generate electricity. Hydropower plants use dams to create reservoirs of water, which are then released through turbines to generate electricity. Switzerland and the Scandinavian countries have many natural resources that make them ideal for hydropower, such as high mountains and abundant rainfall.
