Here you learn how much electricity your household consumes when no one is cooking, ironing, washing or watching television. You also learn how much of that you can save, and how to discover the hidden energy wasters in your household. Just take 3 electricity meter readings over 24 hours - late night, early morning and late night - and enter them into this online StandbyCheck. First, print this PDF form to collect the 3 meter readings, then enter them into this online advisor and have it calculate your "standby electricity consumption", comprised of base-line consumption by appliances working around the clock (fridge, circulator pumps etc.) plus standby consumption (TV, stereo, DSL router etc.).
If you do not have access to your electricity meter, you should ask your building administration to change that.
