According to the US Department of Labor, about fourteen million people telecommute part time and seven million ran home based businesses in 2004. It’s been a while since then, and the number of people working at home just keeps going up, with a sixty-three percent increase in part time telecommuting between 2004 and 2006. Over half of all US companies asked offer some form of telecommuting at the moment.
You’ll want to pay close attention to energy use if you’re working at home, however. Staying home can increase your energy expenditures, and consumer electronics (such as your computer) make up around fifteen percent of usage. Unplugging unnecessary electronics that don’t need to be on is one place to start. Fax machines, printers, and copiers are often kept on, even when they don’t need to be. Computers left on all night are a problem, too. Turn them off and save a couple hundred dollars a year.
Remember to think about phantom load, too. That’s why you should unplug, not just turn off. Many small electronic devices remain in a semi-on state when turned off, so they’ll come back on again quickly. That might just be a few watts, or it might be up to forty watts per device.
Turning your laser printer off instead of leaving it idle will save half the energy, but if you unplug it, it won’t use any at all. Seventy-five percent of the energy used to power electronics is used when they’re off, and it adds up. That’s about ten percent of all monthly power bills. Using a power strip for peripherals lets you be sure that everything is really off, not just in standby.
Power adapters and chargers should be turned off when you’re not using them, too. They still draw power, even if there’s nothing plugged in. Be sure your office lighting is compact fluorescent, not incandescent, and you’ll use less energy, as well as changing and throwing away fewer light bulbs. Choose Energy Star qualified equipment when you can. It uses less power, and it’ll keep your house at a more comfortable temperature by running cooler. Once you start thinking about how to green your home office, you’ll be amazed at all the opportunities there are to do it.
