All these appliances are in "standby" mode - not really doing anything useful, except waiting to spring into life instantly.
For some (but only some) products like printers and copiers, standby can be efficient, decreasing the total energy the device consumes. For others, it's just waste.
Would you believe...
In a detailed study in 2001, the International Energy Agency (IEA) found that from 3% (Switzerland) to a scarcely credible 13% (Australia) of residential electricity used in OECD countries was standby.
"I was amazed when I first learned the dimensions of standby power," said Robert Priddle, IEA executive director. "In my own home, appliances that I thought were 'off' were actually consuming considerable power."
Consumer action could close 24 coal-fired power stations
We could close at least 24 coal-fired power stations, if consumers in all industrialised countries unplugged chargers and switched off their domestic appliances instead of putting them on stand-by.
