Electricity wasted

Sally Lloyd sent me an article called "Getting savvy about standby power" . Here's part of what it says:

Ever wonder how much electricity your household appliances use when they're supposedly off—in "standby" or "ready" mode? Think of the clock on your microwave, your DVD player that's on but not playing a movie, or the little sensor on the bottom of your TV that waits for a signal from your remote control.

It turns out that these "vampire" loads are gradually sucking away power—a lot of power.

An estimated 13 percent of household electricity use, according to a recent study published by the California Energy Commission, is from appliances in low-power mode (which is to say, not performing any of their primary functions).

Standby mode, the least amount of energy an appliance can use without powering down, is just one example. Many appliances have multiple low-power modes.
...
In 2000, a group of researchers from Lawrence Berkeley National Laboratory estimated that each year Americans spend about $4 billion just on standby power.

Generating that electricity puts roughly 27 million tons of CO2-equivalent emissions into the atmosphere (more than 3.7 million cars' worth) every year.
...
If you're looking to reduce your energy use and tread more lightly on the planet, changing your habits is a good starting point.

* Shut your computer and printer down (all the way) when not in use. Some people find it useful to plug all their IT equipment into one power bar, then flip the switch once they've shut down.
* If you have an A/V system that can be turned off entirely without sacrificing performance, do so.
* Keep cell phone chargers out of the wall when you're not charging the phone. Those little power bricks often draw a little current—even when you're phone's not connected.

Sounds like it's worth figuring out a way to turn off the electricity completely when we're not really using it!
