1 Renewable Energy as Share of Total Energy Cheryl Gomez, PE, MBA, LEED AP BD+C /steo_full.pdf U.S. Energy Information Administration Canada, with its large landmass and diversified geography, has substantial renewable resources that can be used to produce energy; these resources include moving water, wind, biomass, solar, geothermal, and ocean energy. Renewable energy sources currently provide about 16.9% of Canada s total primary energy supply. Moving water is the most important renewable energy source in Canada, providing 59% of Canada s electricity generation. In fact, Canada is the third largest producer of hydroelectricity in the world. Wind is the second most important renewable energy source in Canada. It accounts for 1.6% of electricity generation in Canada. Biomass is the third largest source of Canada s electricity generation. Its share in Canada s electricity generation is 1.4%. Wind and solar photovoltaic energy are the fastest growing sources of electricity in Canada. able-electricity/7295 Fossil Fuels (Non-Renewable) Supply Availability - Reserves & Production Natural Gas Liquid Fuels Solid Fuels Price Volatility
