Household energy may save by using compact fluorescent lightbulb (CFL) rather than using ordinary Bulb.CFLs cost is 3 to 5 time larger then conventional incandescent bulbs but it use one-quarter the electricity with longer life time.
A 7-watt CFLs are comparable to a regular 40-watt bulb, 26 watts is the typical CFL equivalent of 100 watts and so on. Another energy saving light source is LED(Light Emitting Diode) which is now under test in house hold .
It is energy efficient and cost effective then any other light source.
