the calculations are approximate, easily scaleable hence using 10 hrs
1w for 10 hrs a day average over a year at 27p a unit costs £1 [3.7 units]
now plugged in day and night for 24 hours is £2.40 per year per watt
now most modern electrical are 1w or less on standby
an example off what i mean
my 900w output microwave uses 1500w in use but only a fraction off the time
on standby 1.1w so £2.40x1.1 so £2.64 now that includes the clock
but more important if you are lazy and leave the door ajar and light on its a shocking 22w or £52 a year or £1 a week just for the light [and clock] so switched off when not in use
for a comparison my new 24" bush tv[argos own make ] uses around 18w medium to low volume and medium brilliance
in general you can use the rating plate on the machine or the 230v specification voltage for input consumption in the manual or booklet
please add your own thought and comments and corrections to my maths or calculations if it off value to the thread
