Elec Usage - Alarm Clock

HD840

This is really sad but....
does anyone know what the annual electricity usage cost would be for having a bedside alarm clock switched on all the time.

I am doing a big energy cutting exercise and I wondered if the annual cost is significant such that a battery clock would be cheaper.

Many thanks.

Not worth worrying about.

Out of interest, how many kwh do you use a day and how much are you trying to cut back by?

yes a battery clock is cheaper to run HD840. I did the readings on an electric alarm clock but cannot remember the data. I switched our bedside clocks off at the plug after getting the numbers. Ok it is only pennies per week but pennies add up. I am expecting our combined energy bill for this quarter to be a total of around £130. We live very comfortably, I cook 2 hot meals every day, bake a lot, central heating is on late afternoon to 8 and employing other methods of saving energy is a habit for both of us. Last 2 quarterly bills came in at <£96

I too was wondering that HD840, but I hadn't quite plucked up the courage to ask.

Power consumption should be written on it somewhere..I've got one that's rated at 10 W, so it will use about a quarter of a unit a day..or 87.6 units per year..on my tariff of 14p/unit, that's £12.26 / year !! That's more than I thought..

You can still get clockwork alarm clocks ..but they're hard to find.. I bought one for about £7 or so.

Cost about £6 year to run.

Batteries could cost £3 or £4 pack.

Wandering the same thing HD..have a Grundig radio alarm Sono clock 35 GB that I used before retiring. Only ratings I can see say 240V 50Hz.
But if that relates to 10W/£12pa... too much.
p.s.... good figures Kittie.

According to this tester:

their alarm clock consumed 3watts.

no real targets to cut by but just looking at everything I can think of.

My central heating control electric clock (with a programmer)shows 13watts when the heating is not on. Know that's right because if I switch it off, this Efergy monitor goes to zero.
13 watts on all the time at 13.745p kwh works out at £15.63 a year. Ye gods.

Thanks to all for your helpful replies.

My radio is 6.5 W so I guess that means around £6 per year....a cheap clock would cost around £5 from Argos and when battery costs are added then well in excess of elec cost.

The HomeEnergy Saving website link is appreciated and very useful.
