Turn lights off when you’re not in the room.
Using compact, high energy efficiency fluorescent lighting can save up to 80% in lighting running costs and they last up to eight times longer than regular (incandescent) bulbs.
They cost a little bit more than normal light bulbs but they are more environmentally friendly. You can buy compact, high energy efficiency fluorescent bulbs at most grocery shops and hardware stores.
During the day, instead of turning on the lights, open your curtains to let natural light in.
