The ocean’s tides and waves represent an enormous, predictable, and largely untapped source of clean energy. Unlike wind and solar, tidal energy is completely predictable — tides follow lunar and solar cycles with precision. Canada’s Bay of Fundy, with the world’s highest tides, is a global testing ground for tidal energy technology.
How Does Tidal Energy Work?
Tidal stream turbines work like underwater wind turbines, generating electricity from tidal currents. Tidal range systems use the height difference between high and low tides. Wave energy converters capture the motion of surface waves. The chemistry of saltwater environments creates materials challenges addressed by advanced coatings.
Canada’s Opportunity
The Bay of Fundy’s 16-meter tides could generate significant electricity. Nova Scotia’s FORCE test centre hosts prototype turbines. Wave energy potential along Canada’s Pacific coast is also substantial. Tidal energy complements other clean energy sources in addressing climate change. Environmental monitoring ensures minimal impact on marine ecosystems.
