Well lets look at one of the renewable resources. Wind is a renewable resource and a pro to wind mills is that it does not destroy ecosystems and pollute our air. However a con to it is that it is dangerous for flying animals, who have actually been killed because they hit.
Water is another renewable resource that is turned into energy through dams. A big pro to this is that the energy produced is massive, and it can power a whole town. However a con is that it DOES destroy habitats that lived in the area before the dam was built.
