Today there is a movement to require any device to use less than half a watt in standby mode. It’s the power that keeps your television tuner, or microwave oven, or coffeemaker’s clock running. With billions of appliances, we can easily waste hundreds of billions of watt-hours. This is sometimes called the “no-load” power loss or, what I prefer, the “vampire” loss. Each plugged-in plug has two prongs that are like the fangs of a vampire, sucking our electrical life’s blood out of us all. Bah, ha, ha, ha, ha … It seems like an important problem to address, and we have, to some extent. Having vampires suck half a watt instead of 10 or 15 watts represents great progress. Nevertheless, how about if it were a tenth of that half? We could have billions of kilowatt-hours available to us for free, without any other decisions about nuclear plants or wind-turbine sites.
