Install efficient lighting

Compact Fluorescent Lamps (CFLs) use 75% less power than old incandescent bulbs, and last much longer. Note that CFLs contain small amounts of harmful chemicals, so please dispose of them safely. Best is to take them to safe drop off points e.g. at retailers like Woolworths or Pick n Pay. New light emitting diodes, or LEDs, are even more efficient than CFLs, and last 130 times longer than CFL bulbs. They have limited applications in homes at this stage, but are ideal replacements for halogen down lighting. They save the most, and although they may be currently expensive the cost is coming down as the technology develops. Of course, switching off lights in unoccupied rooms is also an obvious way to save.
