One of the reason why people's electricity bill is high could be the nightlight they use at home. Try to imagine this, you have a night light that is turned on your hallway and it consumes 7 watt of electricity. This same night light has been turned on for 8 hours everyday for every month. That amounts to a lot of electricity that has been wasted because you are asleep and meanwhile this night light is simply left on, the whole night until you turn it off in the morning. That is a lot of wastage of electricity.
Instead another solution is to buy motion sensor night light which uses AA batteries to power it. You can use rechargeable batteries to power the motion sensor light and it does not remain on the whole night. It only comes on when you happen to pass by it and it stays on for about 45 seconds and then shuts off, waiting for another motion detection. This way you only need to recharge your rechargeable batteries about once in three weeks and best part of it all, is that it takes only one hour to fully recharge the batteries. Buy "Duracell" rechargeable batteries because i find that it last a lot longer than other brands.
