Environmental Impact of Energy Resources
Spec
4.1.3
- Hydroelectric power stations are typically built into dams.
- Dams act as barriers to stop or control water flow.
- Water released from the dam spins a turbine to generate electricity.
- Dams slow river flow, leading to the formation of new lakes.
- New lakes can destroy natural habitats, such as forests, which may be flooded or cut down.
- Animals lose their homes and need relocation due to habitat destruction.
- Human impact includes flooding of towns near rivers, forcing people to abandon homes and farmers to give up land.
- Planning of dams should consider historical and important sites.
