Although commonly thought of as related, energy efficiency and energy conservation are distinct from one another. Both serve to reduce energy use, however, conservation carries a degree of sacrifice, while efficiency is using adapted goods and appliances to exercise the same benefits.
Let There Be Light
Energy conservation means sitting in the dark for a few hours every day.
Energy efficiency means replacing standard incandescent light bulbs with energy-saving compact fluorescent light bulbs.
Beat the Heat
Energy conservation means turning off the AC and opening the windows during a hot summer day.
Energy efficiency means using the Energy Star approved AC, keeping the house a constant, cool 78°.
Ditch the Dishes
Energy Conservation means washing and drying every cup, spoon and plate.
Energy efficiency means having time to do other things while the low-energy dishwasher does all the dirty work.
Loads of Fun
Energy conservation means having to use cold water and overstuffing the washing machine.
Energy efficiency means whatever water temperature desired and properly sized loads in a front-loading washer.
Energy efficient measures, like the ones previously mentioned, do more than reduce energy usage and costs. Even singly, these measures make a difference in the environment. Less energy used means less energy having to be produced, which means less fossil fuels being burned and released into the atmosphere. Less pollution equals cleaner air, which means we can all breathe a little easier.
