This one is about as simple as it gets.
If it’s daylight or you leave a room, remember to turn the lights off. Unnecessary lighting is not only a waste of energy, it’s also a waste of your hard-earned money.
It’s a myth that it’s more efficient to leave lights on for a few minutes rather than turning them off and on again. It’s practically always best to turn off lights when you leave the room, no matter what globe type you have or how long you're leaving the room for.
Try getting creative and attach friendly reminder stickers to your light switches to help your household switch off. Sensors are also an effective way of making sure lights that are outdoors or in stairways, garages and hallways aren’t accidentally left on.
