Energy vampires: "sleeping" computers use 189 kWh of electricity per year: #EnergyEfficiency #SmartMeter

I have a Kill-a-Watt meter can be hooked up to any 120V device and records wattage being used instantaneously and also over time. Cost around $22. Surprised to find my 19 inch TV/monitor draws all of 24 watts, but may reach all of 25 if the volume is turned up. Far and away the average house's largest juice consumer is its heat pump - consumption of course varies but is usually around 65 to 85 percent, as memory serves. I've found that overhead fans are valuable in the heat. The water heater is usually the next sizable consumer (10 to 20%),as I recall. Automatic timers are available. For me it's strictly a matter of dollars and cents. We can make all the cheap electricity we could ever use, if we wanted to. But that's a long story.
