From my calculation 20w will equal up to around 175kwh / year.Dont underestimate the question please. Just 20W x 24hrs x 365days = 96kwh./yr
Most houses use more leccy from things on standby than the rest!
How many switch off the telly at the wall etc. For me this is the quiet scandal of our times polluting the atmoshere to produce leccy we do not need
No. 175 kWh/yr it is. But the qn of thermal cycling items is interesting. Most electronic items follow a bath-tub shaped failure curve. High initial failure rate as the dodgy chips fail, then when those are weeded out, the failure rate is very low indeed for years. Then at the end, the failure rate starts rising again, as the chips become "worn-out", microscopic-sized connections fail, solder joints age & fatigue, etc.From my calculation 20w will equal up to around 175kwh / year.
Am I mistaken?
