Use Energy Saving Bulbs Instead of Incandescent Bulbs.

When a comparison is made of the cost of electricity required by incandescent bulbs (40 W) and energy saving bulbs (8 W) equivalent to 40 watts, the energy saving bulb is cheaper in the long run because the running cost is cheaper.


Switch Off Lights When You Are Not Using.

Switch off the lights before you leave the room and when the room is vacant. Consider ways to optimize your use of natural light from the sun during the daytime.
