Set up Power Management on desktop computers and laptops
The average desktop PC wastes half of the energy it consumes and 75% of energy consumption occurs when no one is in front of the computer! Did you know that a desktop computer left on 24/7 without power management can use up 600 kWh per year? That same computer will use only 200 kWh per year if power management is enabled. Of all the energy savings possible from household plug-in electronics, power management accounts for as much as 40%! By turning on your computer’s energy saving features, you can save over $60 a year in energy costs and reduce your CO2 emissions by nearly half a ton. Learn ten ways to reduce your computer’s energy consumption.
Use the ENERGY STAR® guide to activate power management settings on your computer or run the ENERGY STAR® Wizard for CPUs running Windows 2000 or Windows XP operating systems.
Using a Smart Strip can cut the cost of vampire power in a home entertainment system in half. Even when your TV, DVD player, video game systems, and other electronics are turned off, they are still using electricity as long as they are plugged in. A Smart Strip makes it easy to cut off power to multiple devices when they aren't in use. Plug your TV or computer monitor into the "master" outlet on the Smart Strip, and plug any devices that you want to remain always on, such as a DVR or lamp, into the "constant-on" outlet. Other devices will only come on when the TV or computer monitor does, while devices plugged into the “constant-on” outlet remain on all the time.
Unplug power adapters and small electronics/appliances when not in use
Standby power, vampire power, and phantom loads refer to the electric power consumed by electronic appliances, such as VCRs, televisions, stereos, computers, and kitchen appliances, while they are switched off or in standby mode. A very common "electricity vampire" is a power adapter which has no power-off switch.
Make sure to unplug your cell phone and reusable battery chargers from the outlet when not in use. These use energy even when not charging! You can also save energy by plugging electronics and appliances into power strips and turning them off when not in use.
Studies at Lawrence Berkeley National Laboratory have estimated that standby power may account for 5% to as much as 10% of total residential household power-consumption in the U.S. That adds up to that $3-6 billion in energy costs and is equivalent to the power generated by between 18 and 36 average power stations.
Use clothes lines & racks to dry at least half of your laundry
Clothes dryers use 5-10% of a household’s daily energy use and are one of the most expensive home appliances to operate ($100-$200/year). They are also one of the most dangerous causing more than 15,000 home fires annually. If you would like to know how much energy and money it takes to launder your household’s clothes, try out this calculator.
Instead, line-dry your clothes inside or outside. Explore clothesline and rack options on urbanclotheslines.com. If you think that your homeowner’s association or condominium prohibits the use of clotheslines, here’s some good news! Maryland’s “Right-to-Dry” legislation (SB 224) went into effect on October 1, 2010 and requires condominium associations, homeowner associations, and cooperatives to allow homeowners to install clotheslines on their property. Learn more about the benefits of air-drying clothes.
TIP: Using hangers can really reduce the length of clothes line you need. (You’ll need a rod or taut wire for this approach). Use each hanger as a mini-clothes line for socks, dish towels, and the like. Install a rod over your washer dryer or use your shower rod for hangers during rainy or winter weather.
If you have severe allergies to pollen, check the weather and the Air Quality Index before you hang your clothes outside.
