Yes, for hydroelectricity

the best thing in the world

hydropower is considered a renewable resource because it comes from earth's water cycle

the water doesn't get polluted from passing through a dams turbine

no fuels are burned from hydropower unlike fossil fuels

the only problem is that thousands of fish can die

water at the bottom of a lake created by a dam is cold and not oxygen rich.And if the warm oxygen rich water with fish in it is mixed with the cold water the fish can die
