Energy cost to power an alarm system?

You're kidding, right?

For a 24VDC 2AMP system, it costs about $1.25 per month in my state (Oregon) where electricity costs roughly $0.07 per kilowatt-hour.

Just did the calcs on my home system and it's about 5-6 bucks a year.

2 amp ? that's pretty big.

And now you know why the big companies' contracts require the customer to furnish the electricity through the customer's meter and at his expense.

Less than a single dollar. The transformers which power alarm systems typically provide around 65 mA at 16.5V. They draw less than 1/2 an Amp at

120VAC. One I use frequently draws 0.43 Amps. Watts = Volts x Amps, so the transformer in question draws 5.16 Watts. There are 730 hours in the average month. 730 x 5.16 = 3. kWh per month to power the average alarm system.

If you were paying $0.10 per kWh your alarm should cost about 37 cents a month in power. I have no idea what your power company charges (actually, I don't even know what mine charges:)) but that should give you a fair approximation.

Wow only $0.07 per kilowatt-hour!

Here in the UK it's about $0.20

I'm paying 16.9¢ here in Texas, USA.

We're at 6.1 cents according to my last BCHydro bill.

pretty lucky my BC friend!! here we used to have the lowest price on electricity in NA but since our libearal party ass holl got in power he got us from a bit less then 5 cent a kW/hour to 7,3 cent in about 3 year

Some people here (well actually 1) stated that we are spoiled since our gas prices are low so we apparently are also spoiled by low electrical costs however I shant comment about that lest I be chastised by those (that) previously stated people (person)

The increased cost you pay is due to taxes

I get my electric rate per kWh by dividing the amount of my monthly bill by the kilowatt hours I have used. This includes all the transmission charges, taxes, and various fees for this and that.

So that stated 9 cents per kWh could actually be 11 cents per kWh!

I can't imagine being on 220v in the UK helps much either.

That in itself should double the cost over our 110v :)

Twice the voltage requires half the current. Theoretically it should make no difference, but in reality there should actually be a small savings with 220 because of reduced losses in the wires. Probably not a noticeable amount, but...

I'd have to imagine that the mortality rate in deaths due to electrocution has got to be a lot higher too. Who hasn't seen a kid stick something into a wall outlet?

I heard of a DIYer that was receiving instructions over the phone and was electrocuted when he was told to screw the..............electrical outlet. Obiviously, either the reception on his Vontage phone service wasn't all that good or the instructor had his mouth full of hamburger. The rest is history.

Yeah, but I'll bet you he was ecSTATIC when he died.
