hi there,
i've been wondering (haven't done anything other than that) about how much electricity i use and whether i could calculate things like, how much electicity i use in 4 hours, watching dvd's or 6 hours of sky and working on my laptop and then how much that costs me.
so, is it a case of checking each device for the amount of watts it uses, adding these up, multiplying the total by the number of hours they are on to give me the total number of watts used and then working out how much its costs based on how much a kilowatt per hour costs me?
if the devices don't specify how many watts they use what options are there in finding out?
thanks
