Energy efficiency can reduce greenhouse gas emissions and the depletion of natural resources.
Energy Conservation – Energy Conservation is the practice of reducing the demand for energy, meeting demands efficiently as possible, supply energy from low carbon and renewable energy sources, carbon off-setting, use of energy efficient products, purchasing energy efficient materials, and avoiding products that are energy vampires that draw power when off. Using less energy to fulfill the same function or purpose; usually attributed to a technological fix rather than a change in behavior, examples include better insulation to reduce heating / cooling demand, compact fluorescent bulbs to replace incandescent, or proper tire inflation to improve gas mileage.
