What is energy efficiency?
Something is more energy efficient if it delivers more services for the same energy input, or the same services for less energy input. For example, when a compact florescent light (CFL) bulb uses less energy than an incandescent bulb to produce the same amount of light, the CFL is considered to be more energy efficient.
Why should I care about energy efficiency?
Improving energy efficiency can make a real difference. It saves money, reduces carbon emissions and decreases your country's dependence on foreign energy supplies... all at the same time!
You can contribute to energy efficiency improvements in your everyday life. See "What can I do to save energy" to learn more.
