- Hydroelectric Power
- Advantages
- Readily available - water can be stored in reservoirs
- Higher energy density
- No pollution after manufacture
- Reservoir creates new habitats and can be used recreationally
- Disadvantages
- Visual and ecological impacts
- Expensive to repair
- Construction expensive - takes many years to make profitable
- Nearby land flooded - habitats and infrastructure
- Disrupts fish migration
- Changes in flow fluctuations downstream
- Dead organic matter decays - release CO2
- Suspended solids sinking reduce water turbidity and increase light levels
- Location
- Steep slopes - fast flowing streams
- No land use conflicts
- Close to consumers or energy grid
- Large water volume
- Impermeable rock under reservoir
- High Head Scheme
- Low volume of water
- Water falls long way down hill
- Passes through a turbine
- Low Head Scheme
- High volume of water
- Dam built on large river
- Smaller head of water
- Run of River Scheme
- Turbine on a river without a dam
- Little/no water storage
- Advantages
