Read to Learn!

Energy efficiency means using energy more efficiently

and usually involves a technological change. It refers

to a method of reducing energy consumption by using
less energy to attain the same amount of useful

output. For example, an energy-efficient 12-watt LED

bulb uses 75-80% less energy than a 60-watt traditional
21
bulb but provides the same level of light.
