I borrowed an electricity power meter for a few days and went around the house measuring everything. A couple of interesting discoveries:
Total standby power of devices in the house = 28.5 watts This is sort of invalid because the monitors on my 2 tower PC's are on a switch that turns them off when the PC is off so their standby power is less then. Also the meter seemed to register in increments of 0.5 watts. My new washing machine consumes 0.5 watts when not in use so have to switch it off at the plug in future. My old gas oven consumes 4 watts all the time - for a clock? My two Humax PVR's also each consume 3 watts on standby. In use the PC's consume 49 and 79 watts each, but in sleep/suspend mode about 2.5. The washing machine consumes 0.5watts when it is not in use. This means 1Kw every 2000 hours. 2000 hours is 83 days. 365/83.333 = 4.38 Kw/yr. My current rate is 28.445p/KWh, so it costs me £1.25 a year just leaving it plugged in and not using it. So just my thoughts on saving some money. A rough calculation gives a cost of £62.5 per year keeping the house on standby.
