Hydroelectricity wreaks a huge amount of damage even if it is a renewable source of energy. For example, if a hydroelectric dam is placed too close to a fault line its activity can potentially cause an earthquake. Additionally, the massive displacement of water needed to create hydroelectricity completely changes the surrounding ecosystem which can have devastating effects on local marine wildlife, especially on the migration patterns of fish. There are certain solutions and precautions which can reduce these damages, such as fish ladders, but on the whole the massive amounts of environmental damage caused by hydroelectric dams are not safe.
