Stop Bleeding Energy

Salon has an article about saving energy by cutting off "energy vampires" in your home (see excerpt below). The article mentions using energy monitors, which are available at our partner site.
There are insomniacs in our homes that work late at night and run up the electricity bill. They are not the classically overworked American who pops melatonin or Tylenol PM. They are microwave ovens, computers and TVs. They are half of our appliances, electronic equipment and associated chargers that suck down power even when they're turned off, in sleep or standby mode. A typical house hosts around 50 such insomniacs, and though individual devices use minuscule amounts of electricity, in the aggregate they're an astonishing and pricey burden.
This "vampire energy loss" represents between 5 and 8 percent of a single family home's total electricity use per year, according to the
Department of Energy. On average, that's the equivalent of one month's electricity bill. Taken across the United States, this adds up to at least 68 billion kilowatt-hours of electricity annually; that's the equivalent output of 37 typical electricity-generating power plants, costing consumers more than $7 billion. This wasted energy sends more than 97 billion pounds of carbon dioxide into the atmosphere; on a global scale, standby energy accounts for 1 percent of the world's carbon emissions, according to Alan Meier of the Lawrence Berkeley National Laboratory, based in California.
"When a consumer thinks the device is off, it should be using as little power as possible," says Meier. "But in their haste to get products onto the market, manufacturers don't make those modest design improvements, and we, the consumers, pay the price in unnecessarily high standby power use."
Luckily, there are a number of new gadgets that make it easy to thwart vampire energy loads. For places with clusters of cords like a home office or entertainment center, use a Smart Strip. By monitoring power consumption, the strip detects when computers or stereos are off and powers down, eliminating energy usage in all peripheral devices such as printers. Another option is the Isolé power strip, which uses a motion sensor to turn off six of its eight outlets if it hasn't detected anyone in the room for up to 30 minutes.
To ascertain what appliances are sucking the most power, you can buy a Kill a Watt power meter, a nifty gadget with a wall outlet that measures the watts, volts, amps and kilowatt-hours of a given device when off or on. I bought one and spent a fun-filled few days discovering the power my appliances were wasting. While my electric toothbrush and cellphone charger suck less than a kWh per day (around $5 a year), my VCR, which I seldom use, takes three times that much. I don't have a plasma TV, but if you do, it's likely using over 1,400 kWh per year (the equivalent of about $160) if plugged in but not technically "on," according to a 2005 Department of Energy report. A
Federal Energy Management Program Web site supplies information about the standby power wattage of office equipment such as computers, fax machines and printers.
