Energy efficiency and energy conservation are two similar, but different, methods of reducing overall energy usage. Energy efficiency means achieving lower energy use through specific steps, such as installing appliances, equipment, or lighting that uses less energy. For instance, replacing your current refrigerator with an ENERGY STAR refrigerator would be an energy-efficient move. Energy conservation, on the other hand, means changing your behavior in order to save energy, such as turning off unnecessary lights and using your air conditioner/heater less frequently. By finding ways to conserve energy and become energy efficient, you can not only reduce energy bills, but also decrease the need to generate electricity.
Did You Know? Replacing standard incandescent light bulbs with compact fluorescent light bulbs (CFLs) can save 75 percent of lighting costs.
