Harnessing tidal power has positive impact on climate change because it produces no greenhouse gas emissions.

Tidal wave energy is among the key sources of renewable energy available on our planet. 

Wave energy is as source of power that comes from the endless march of the waves as they roll into the shore then back out again.

Humans harness this power along the coastal regions of the US, Canada, Europe, and Australia. The best thing about wave energy is that it will never run out. 

There will always be waves crashing upon the shores of nations, near the populated coastal regions. The waves flow back from the shore, but they always return. They require no input from man to make their power, and they can always be counted on. The first modern commercial tidal power was installed off the coast of St. Malo (1965), in France. It has been producing 240 MW with every tide using a tidal barrage. The other solutions generating electricity from tides are:


  • Renewable, emission-free and reliable. A plant can last 100 years
  • High efficiency, predictable output
  • Could potentially provide a storm surge barrier.
  • Environmental impacts are local, not global


  • Very location specific and expensive to build
  • Barrages may restrict access to open water
  • Impact on fish, marine mammals and birds
  • Might decrease salinity in tidal basins
