Vampire Slaying and More: NRDC's Halloween Energy Survival Guide
Along with being a fun holiday for tricks and treats, Halloween is an opportune time to shine a ghostly light on the evil energy vampires lurking in our homes. By these we mean those ghoulish fangs – also known as plugs in the wall – sucking frightening amounts of electricity all night (and day) long, even when our bloodthirsty electronics and appliances are turned off or doing nothing useful.
The chilling truth is that as much as one-tenth of the electricity devoured in our homes vanishes as “standby power” – electricity feeding our perpetually plugged-in electronics and appliances even when they’re idle for long periods of time, like in the dead of night.
But you can drive a stake through these energy demons by following this Halloween Energy Survival Guide. Not only will it help save money on your utility bill year-round, it also can avoid the nightmare of millions of tons of dangerous pollution from power plants generating extra electricity to satisfy our energy-gobbling appliances and electronics when they are not being used. Here’s what you need to know to protect yourself:
Your cell phone charger is not the boogeyman – Although these chargers once consumed 2 to 4 watts of power if plugged in with no cell phone attached, today’s chargers only use 0.1 watt or less in this ghostly condition. Your microwave oven, on the other hand, draws as much standby power as 35 new cell phone chargers do annually. While unplugging your charger will save some energy, there are far more menacing energy fiends haunting your home.
Save up to $100 a year by making sure your game console “sleeps” when you do – Video game consoles like the PS3 and Xbox 360 only use 1 watt of power in standby mode waiting to be turned back on. But if your child or roommate forgets to turn off the console after playing a game or watching a movie, it can -- if left on indefinitely -- gorge on 60 to 100-plus watts of power, wasting $50 to $100 worth of electricity each year. To slay the vampire: Go into the console’s user menu and enable the Auto Power Down feature, allowing it to automatically power down after extended periods of inactivity.
Your cable or satellite set top box uses near full power even when “off” – NRDC took measurements of set top boxes provided to customers by companies like Comcast, Time Warner Cable, Direct TV, and Verizon, and found the devices gobbled around $3 billion worth of electricity in 2010 – and a giant two-thirds of it in standby mode. Turning off the box merely dims the clock in some cases, or at best, stops the DVR’s hard drive from spinning when not recording a show. To slay the vampire: a) ask your cable or satellite company for a set top box that meets at least ENERGY STAR Version 3.0 and, if available, b) request a whole home DVR for your main TV and a thin client, instead of a regular box or DVR for your second and third TVs. This combination will allow you to watch recorded shows on any TV in the home and result in lower overall household energy use, and c) unplug the set top box on seldom-used TVs (possibly in your guest room or vacation home). Fortunately, the industry is working really hard to make these boxes more efficient, putting us on track to save roughly a billion dollars in electricity costs via better-designed boxes that have recently entered the market.
Buy a green TV and choose the right settings – Today’s new flat-panel televisions use far less energy than the models from just a few years ago. Buy a TV with the ENERGY STAR label or better yet, one that meets EPEAT’s criteria ensuring it’s not only energy efficient, but also has very low levels of toxics, is designed to be easily recycled, etc. To slay the vampire: During set-up of your new TV, select the home or standard setting, which avoids the overly bright “vivid” or “retail” settings that burn an extra 15 to 20% of power. And don’t choose “quick start” unless you really need it. Most TVs today use enough power in standby (0.5 watts or so) to recognize your remote control’s signal when you want to turn it on. With “quick start” the TV might turn on slightly faster but is also likely to consume substantially more standby power during the 15 to 20 hours it’s turned off every day.
Don’t Watch Dracula (or other movies) from your game console – Many of the newer TVs are internet-ready and allow you to stream a movie from Netflix without another device. The next best thing is to access movies via a small box, such as Roku or Apple TV that use 5 or fewer watts to stream. To slay the vampire: Never use your game console to stream movies because it uses 10 to 20 times more energy.
Ensure your computer sleeps when you’re not there – There’s no need for your computer to be fully awake if you’re not using it. It can reawaken in less than five seconds when you shake the mouse button or lift the laptop’s lid. To slay the vampire: EPA recommends adjusting control panel settings for the monitor/screen to turn off after 15 minutes and the computer to go to sleep after 30. You can adjust these settings to meet your needs but the key is for the computer to turn off when not in use. A typical desktop computer and monitor left on 24/7 can waste $40 a year in electricity compared to the same desktop set to go into sleep mode when unused. Meanwhile, running a continuous slide show or screen saver of your family or pet wastes money because it prevents the computer from going to sleep, making it work harder than necessary when no one’s there.
The new vampires are data modems and routers – Almost every home with high-speed internet service has a modem to transmit data and a router to move it around to your laptops and tablets. A recent NRDC study found these devices consume roughly $1 billion of electricity annually – and drink almost the same amount of energy when receiving email as when skulking in the dark at 3 a.m. To slay the vampire: Look for models with the ENERGY STAR label as new, more efficient devices with better power management are starting to hit the shelves.
Settings matter everywhere – Even if you buy the most efficient air conditioner, heater, or water heater on the market, your energy savings are highly dependent upon the settings you select. To slay the vampire: Use a programmable thermostat to ensure your home is not wasting energy keeping cool in the summer or warm in the winter when no one’s there. Set the temperatures on your gas or electric water heater only as high as you need it. Otherwise it works harder than necessary to make sure hot water is always ready for you. And if the water from the tap almost burns your hand, the water heater setting is too high and you’re probably throwing away a few $20 bills down the drain every year.
In other words, you don’t need garlic and wooden stakes to ward off the terrifying vampire energy predators -- you can simply “off” many of them with the right buttons and settings.
