Saving electricity is the need of the hour. Electricity can be saved by adopting various techniques like switching off the lights and fans when not in use, using (LED) Light Emitting Diode bulbs. The LED bulbs are solid light bulbs that are extremely energy-efficient, they do not scatter light like normal bulbs instead the light is directional. They last up to 10 times longer than CFL and are mercury-free.
