Is hydroelectricity a renewable or non-renewable energy source?

    Hydroelectricity is renewable energy in that the source of that power is naturally replenished (at a rate higher than the rate of consumption, which in this case is zero, because the water is not “consumed”). But while hydroelectricity is renewable it does tend to have significant, and harmful, impacts on the environment. These harmful effects on the environment are often the result of damming which destroys natural habitats and displaces wildlife, furthermore, dams require considerable energy expenditures to be built, so most dams probably have huge carbon footprints. On balance though, hydroelectricity is probably good for the environment.
