In the past several years in Canada, the utilization of renewable energy has become a priority, especially in the forms of solar power and wind power. Another form of renewable energy in which Canada is beginning to see potential is that of wave and tidal power. Though much of the country’s focus has been on the aforementioned solar and wind industries, Canada’s eastern and western coasts make wave and tidal power a natural choice as the next energy on which to focus.
Much renewable energy is harnessed for the production of electricity to power homes and offices. While biofuels, wind, and solar energy are making strides in Canada, wave and tidal power has not received the same amount of attention. This may soon change due to the amount of ocean available on both coasts and to the north. In fact, these coasts are capable of producing a quarter of Canada’s annual electricity consumption through wave and tidal power. And because the waves and tides are a consistent natural force, wave-powered energy production is more dependable than that provided by the intermittent sun and wind.
The perception that Canada is lagging in the wave and tidal power department is partially due to its overshadowing accomplishments in solar and wind power. In actuality, Canada trails only the United States and United Kingdom in wave power development. Natural Resources Canada is helping future wave and tidal projects by creating an atlas that points to useful locations in which to construct wave and tidal power plants.
Nunavut is one such location. Meaning “our land” in Inuktitut, it became independent of the Northwest Territories in April of 1999 and comprises a large portion of northern Canada. Consisting of just over 29,000 residents spread over a region the size of Western Europe, it is an ideal location upon which to set up onshore wave and tidal power systems. Because the residents that live along Nunavut’s water do not use the shores for recreation, the concrete and steel structures of a wave powered turbine would not interfere with swimmers or boaters. Furthermore, in the waters of Nunavut and Canada’s eastern and western coasts, there are plenty of available oceans for offshore wave and tidal power systems.
Riding the waves in order to create the pressure needed to move electricity-producing turbines, the bobbers and hoses of a wave power system require no power besides the renewable energy of the earth’s waves to operate. Canada has more than enough shoreline to me use of wave and tidal power technology.
