How is electricity misused?

Turn off your TV when you leave the room as well as the lights. If you're going to do something "quickly" it usually won't be as quick as you expect so turn off any appliances that are on. If possible, unplug some appliances because even if they're off, they still train little to nothing of electricity if they're plugged in. Get energy efficient light-bulbs and products. Also use as little appliances as possible, especially if you're using more than one. It's either this or that. :D
