Renewable energy refers to several energy sources that 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. Renewable energy case studies illustrate the importance of renewable energy and provide information on the cost-effectiveness of the projects, energy and technical statistics, and environmental impacts of the projects. The projects serve as prime examples of how renewable energy can be implemented into the Canadian energy market. Canada is fortunate to have abundant renewable energy sources. The future of renewable energy is becoming more promising because of numerous environmental benefits it offers.
