Hydropower as the method of converting a flow of water into electricity was first created in 1892.
Hydropower relies on the building of dams which can change the eco-system, natural flow of water and even displace wildlife and entire communities of people.
Hydropower works by converting flowing water into energy.
Harvesting hydropower poses a risk to fish and other aquatic life and when bioenergy comes from burning crops, harvesting the large amounts of crops needed to create fuel poses a risk to our food supply.
With hydropower, water is forced into a dam and then pushed through a large turbine that creates electricity.
