Energy efficiency and energy conservation aren’t the same thing, but they have a similar (25): to reduce energy
use. Here’s the difference. Energy conservation relies on people cutting back on activities that (26) energy—by
turning off lights or driving less or using appliances less often. Energy efficiency harnesses technology to help
avoid or reduce energy (27) so that you can still turn on the lights, drive, or wash your clothes but use less energy
