Renewable energy in Canada Renewable energy in Canada The majority of the energy supply in Canada is generated by renewable technologies. The country generates the majority of its electricity from hydroelectric dams (59% in 2006). Wind power is a fast growing sector of the energy market. Globally, Canada was the 6th largest producer of wind power in 2011. Canada has built many photovoltaic power plants, mainly in Ontario, with one in Sarnia being the largest in the world at the time of construction. A 15-megawatt tidal plant sits at Annapolis, Nova Scotia, and uses the daily tides of the Bay of Fundy. Politicians have
Bay of Fundy various rivers which empty into it. Near the mouth of the Saint John River, where it passes through the city of Saint John, is the famous Reversing Falls. Here the changing tide causes alternating strong upriver and downriver flows several times a day as the tidal cycle changes. A narrow granite gorge and rocky bottom heavily restricts waterflow and creates strong rapids that flow upriver at high tide, and downriver at low tide. Rivers in the upper Bay of Fundy have a smaller flow-rate than the Saint John, and a shallower slope. As a result, extensive mud flats are deposited
