Adam got himself an Electrisave over Christmas. It clips around the main electricity cable coming out of the meter and transmits usage information wirelessly to a desktop unit that you can move around the house. He reckons that with a bit of investigation work he's going to knock over 50% off his electricity bill as a result of knowing what costs what. The biggest culprit is devices on standby. A treadmill in the garage that looked turned off was costing 2p an hour on standby. Doesn't sound much but that's 48p per day which multiplied by 365 is £175.20 per year! That more that paid for the unit (about £65) and saved lots of greenhouse gas ;)
