I bought a plug-in energy meter which measures and records how many watts, kWh, etc are being used by an appliance.
I measured a year 2000 freezer that is chewing more than 3 kWh a day. I think the thermostat may have gone but it's going to be replaced with something newer and more efficient that should use a third of the power real world (or a quarter if you go by the technical specifications).
At current electrical prices the payback period will be about 2 and half years and factoring in increasing prices that will drop to two years.
Is anyone measuring the usage of their appliances?
How much electricity are some of your appliances using and costing you?
