Always use timer of AC. Keep all the lights and fans switched off except of the room in which you sit. Use 3-4 star rated electric appliance and keep the windows and doors opened whenever possible to keep the house well ventilated.Also CFL can be used in place of Tube lights.
Using bulbs of low watts and now-a-days there are energy saving bulbs and lights that are cheaply available in the market which comes in handy when it comes about saving electricity....
simple tip i give you, when you use electricity , you just think that whether it is useful for you or not then use it. dont use unnecessaryly electricity , dont waste current by leaving the fans etc without offing them when we are not using them
