How Much Does That Cost to Run?

At Homecamp, a figure was thrown out that if something consumes 1W continuously, it will cost a pound a year to run.

1 watt * 1 hour = 1 watthour
1 watthour * 24 Hours = 24 watthours
24 watthours * 365 Days = 8760 watthours = 8.76 kilowatthours
1 kilowatthour = 8.304p ()
8.76kwh * 8.304p = 72.74p

i.e. Running 1 watt for 1 year = cost of 72.74p.

Hope that helps?

the link http://www.tescoenergy.com/tesco/U%E2%80%8BtilityResources/expert.html doesn't seem to work for me

but the price for 1kWH seems cheaper then I've heard quoted before... I thought it was more like 11p?

Hi Dale,

Strange, it's working for me:

- looks like the URL picked up some escape chars above.

The price looks current according to that forum (Nov '08 for domestic users).

This page looks more in-line with your figures:

The Energy Helpline () person I've just spoken to said that it varies tremendously based on location:

For Brighton, British Gas, Click Energy v.6 - 19.164p for 1st 125kwh/q and 8.783p thereafter.

For near Heathrow, npower = 9.450 per kwh, with a standing charge of 15.82p per day.

Interestingly, I couldn't find a very good guide for this online, does anyone know of one?

So, after some interesting correspondence and bouncing ideas around, the consensus is that the most useful way to think about cost is - or £1000 per kilowatthour over a year. There are some serious savings to be had out there people!

Here's an interesting page looking at some real-world power consumption data:
