Many of those gizmos which are "always on", by themselves, use very little electricity. But when every single electrical thing in the house is always on, that can add up!
Like if you buy a soda pop for $1 every day. That is just a dollar. Add it up and that is $365.00 a year!
I went around the house adding switches or "switchable to off" power strips to everything which was always on. Just about everything was always on! Even some air cleaner fans and the kitchen blender. Anyway turning all that stuff off when not in use saves me about $15 a month (or $180.00 a year) on the electric bill.
Following is a paper which lists the power usage of many of these items...
i need to get some wall lights for the front porch. i can just get regular lights. but motion sensing would be kind of a security feature. so i thought that if they use VERY LITTLE power, i could use them. normally the light itself would hardly ever be on.
i am figuring that these have sensors that would not turn the light on if it is daylight out ?
I have sensors in every bathroom and my utility room (furnace, washer, drier and second refrigerator/freezer) just because of the convenience and energy saving is a bonus. This is in spite of the cost of a good switch that can be adjusted for time and sensitivity.
When you get up in the middle of the night and can walk into a bathroom with the light that goes on and have the light go off a bit after you leave it is a pleasure. The only problem is going into the shower and having the light go off and leave you in the dark because you forgot to lock it on when you entered. In the utility room, when you have a load of groceries or washing it is a god send to have light ans along as you are moving around you have lighting and it takes little to wave your hand and reset it.
The only problem is that they are not compatible with some CFLs.
