  • 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


  • 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
