What potential harm to the environment does your type of energy cause?

* Hydropower does not cause any pollution and in some ways help the environment, but there are a few things that can cause some problems with animals like...

* Dams have a major impact on rivers and their surrounding ecosystems. They change the normal flow of water which affects the plants and animals living downstream from the dam.

* They can prevent fish from migrating upstream.

* Dams also may force people from their homes because they may flood areas upstream where people live. However, dams can help prevent flooding, and water in a hydroelectric plant is released back into the river without any pollution, so it is a clean energy source.
