Out of all the renewable energy options, hydro powered dams have been a very popular option. Many see it as one of the cleanest options which produces lots of energy. However, dams and reservoirs are currently — and have been for a long time — caused all kinds of harm to the environment and water eco systems.
Some of the damage the hydropower effort have had includes:
- Contributing four percent of all human emissions.
- Pollute water ways.
- Blocks the natural developments of the rivers, waterways and the eco systems.
Efforts are under way to remove dams and other water structures that are already having a positive effect on the water eco systems in those regions. There is no need to let government make the push for renewable energy, when there are already plenty of resources available, even in the United States.
