Changing the way you light your home can make a real impact on the amount of energy you use. Standard light bulbs emit 98% of the power they use as heat, which uses a lot of electricity.
Energy saving lights pay for themselves over the course of their lifetime. Changing your light bulbs to a compact fluorescent light bulb (CFL) will save about Naf. 60,- a year. It uses 75% less energy and lasts about ten times longer than an incandescent bulb.
Take the Bulb Pledge and next time you need to replace a light bulb, buy and install an energy saving bulb instead.
