The term, renewable energy, refers to several energy sources that share one characteristic: they all produce electrical, thermal or mechanical energy without unnecessarily depleting resources. The renewable energy sources are generally classified as water, biomass, wind, solar, earth and energy from wastes. (Note: "water" usually means hydroelectric energy, while "earth energy" means using heat stored in underground rocks and water.)
Canada is blessed with abundant renewable energy sources. The future of renewable energy is becoming more and more promising with the numerous environmental benefits it offers. Furthermore, with recent advances in technology, it is also becoming less costly to implement. The sites listed below give additional descriptions of the main renewable energy sources, and also of their use in Canada.
