How much electricity/cost

[UKBoB]

As kids, most of us were told daily "Turn off your bedroom light, its wasting electricity" ...

Anyone know just how much various appliances cost to run for an hour, a day, etc.

A bedroom light at say 60watt is going to use little electricity compared to a TV which could be 300-400watts? (guess)
I used to tell my stepmum not to use the hoover so much cos its 1300watts and uses more electricity than my hifi

You tend to burn less money by leaving a light bulb on rather than switching it on and off.

I seem to remember it costs a penny to run it for a few hours but switching it on and off wears the gumbins inside and means you have to replace more often.

rule of thumb was if you where leaving the room for an hour or so switch it off if you where going back in soonish leave it on

I suspect the cost of lighting a house is a couple of quid a month - if so then there is no point in ever turning lights off to save money. Im sure one 30 miute vaccum cleaner session or oven roast costs more than 3 months electricity, but then thats just a guess at best.

So whats the bloody point of turning the lights off after leaving a room? Not that I do, or care (just like asking questions, is all)

A 60W bulb can run for 16.6 hours to use up a unit of electricity (don't know how much it is per unit at the moment, maybe 6p)

So for a suingle unit:

A 100W bulb can run for 10 hours.

A 250W television can run for 4 hours

A 1300W vacuum cleaner can run for 45 minutes

etc

So you can see whether you are about to tuck into a delicious slice of roast dinner, or an untasty vegetable

[Incorrigible]

A unit is a kilowat hour, ie how much electricity a 1Kw appliance will use if you have it on for an hour

or a 100w bulb for 10 hours
or a 60w bulb for 17 hours (16 2/3 as mentioned earlier)

A TV (or other appliance) left on "standby" uses about 85% of the power it would if left switched on...

No it does'nt, the main powerf useage in a TV is the CRT tube, since this is not operating when the TV is in standby mode, I'd say its more like 5%
