- Underwater turbines spin with tide movements
- Turbines connected to a generator
Tidal power
Indonesia will be home to the largest tidal power plant in the world
Novrida Masli
Pros
- Consistent Power – Tides move constantly day & night (consistent generation capacity)
- Pollution-Free no greenhouse gas emissions or water pollutants
- Low Operating Costs – few ongoing operating / labour costs
- Renewable – No material resources used or changed
- Minimal Visual Impact – fully or nearly completely submerged in water well offshore
- Efficient – ~80% of kinetic energy → electricity
- Locations – numerous locations coast of British Columbia, Canada has 89 alone
cons
- Device Breakdown – ocean storms, corrosion. ▲ cost of construction to ▲ durability
- Shifting Tides – Changes in tidal movement could reduce efficiency
- Marine Life Affected Sea – life harm by blades, floor mounting could disrupt habitats
- High Initial Costs – lengthens the payback period, could be cost prohibitive
- Few Implemented – few commercial installations compared to such as wind & solar
- Reduced Sea Usage – footprint reduce shipping and recreation areas
