One main advantage is that the water is free. This means that when you create a dam, you don’t have to pay for the water because the rights to use it comes with the land that is purchased for the project. Another pro is, dams provide nearly constant electricity. The damning of a river allows for a constant flow so there is no worry about there not being enough water to power the hydroelectric dam. Also no chemicals are used, so the water isn’t polluted. Even though the water may be warmed and effected in other ways the water is not chemically altered. Other than the setup of a hydroelectric dam where the making of the cement contributes to global warming, it creates very minimal pollution because there is
