Eco-friendly Tips for Your Computer
|
These days, many of us are looking for ways to conserve energy, both to help the environment and to save some cash: buying energy-efficient light bulbs and appliances, adjusting the thermostat, and trying to “reduce, reuse and recycle” where we can.
But we may be overlooking one thing that can be a huge energy drain, increasing our monthly utility bills and needlessly filling up landfills—our computers.
According to the Environmental Protection Agency (EPA) and the Western Sustainability and Pollution Prevention Network (WSPPN), Americans:
- Generate more than five billion pounds of computer waste. (EPA)
- Dump 82 percent of computers in landfills instead of recycling them; in 2007 alone, more than 40 million computers were dumped. (EPA)
- On average, discard their PC after only 30 months of use. (WSPPN)
Here are some easy steps you can take to keep your PC green and energy-efficient: you can help protect the environment and save yourself some money at the same time.
Turn off your monitor
A monitor uses a lot of energy, more than you may realize—it accounts for roughly a third of the electrical usage of your entire computer.
Configure your monitor’s sleep feature to automatically power down when you’re away from the computer (look for “Power Options” in the Control Panel). This sleep mode still uses some energy, so at the end of the day or if you’ll be away from your computer for awhile, turn off the monitor.
Turn off your screensaver
Screensavers were originally designed to protect older monochromatic monitors, a type of monitor that’s rarely seen anymore. Newer monitors, such as those that use LCD or LED technology, don’t need screensavers at all.
Animated screensavers can be fun but they consume as much energy as a monitor in use, not to mention wasting CPU and memory power and unnecessarily heating up your PC, which in turn requires more fan power to keep it cool: it’s a domino effect that all adds up to a needless drain of energy.
Turn off the screensaver. According to the Environmental Protection Agency (EPA), turning off the screensaver can save you from $25 to $75 a year on energy costs. This may not seem like a lot, but think of it a different way: it’s like getting a $50 check for your birthday every year just by turning off something you don’t need—your screensaver.
Use energy-saving modes
Many people leave their computers powered on around-the-clock—often, this is to avoid a lengthy boot-up process, but sometimes we want to leave our PCs on so we can access them remotely or so that automated maintenance processes can run.
One way to combine energy conservation with the convenience of an “always-on” PC is to enable standby or hibernate mode (also one of the “Power Options” in Windows). With these energy-saving modes, you can set your PC to ‘sleep’ after it’s been idle a certain amount of time, and the computer will only ‘wake up’ when you return or when it’s running maintenance tasks.
So what’s the difference between standby and hibernate?
- Standby: With standby mode, your PC uses very little power; some is still used, but the power to items such as your monitor and hard drive is cut. When you come back to your PC, you’ll be up and running quickly, but your computer will be using more energy than the hibernate mode.
- Hibernate: With hibernate mode, your PC is not using any power at all. Of the two, this mode definitely saves the most energy, but the time it takes for everything to power up will be a bit longer.
Keep your PC tuned
For any of your appliances, proper maintenance reduces waste, and the same holds true for computers. Much like a car, a properly tuned computer can run more efficiently: a lean PC uses less electricity and performs much better.
Over time, PCs get bloated and inefficient: settings become outdated as you add and remove programs, clutter is left behind from web surfing, resource-hogging startup commands are needlessly running. This PC detritus that builds up through daily use acts like “friction” on your computer—and the end result is that everything your computer does requires more effort, takes more time, generates more heat, and wastes more power.
And an added benefit: by keeping your current PC in good running condition, you’ll also be able to hold on to it longer, saving you the costly expense of a new computer.
Recycle your old PC
Eventually the day will come when you’re ready to say goodbye to your old computer. When that happens, rather than throwing your PC away and adding to the world’s growing waste problem, why not recycle it? Research by the EPA found that in 2007 only 15% of discarded computers were recycled. And many of the computers that ended up in landfills could have benefited our community by being donated to charities, schools, or other non-profit groups.
If you’re not sure where you can recycle or donate your computer, the non-profit organization TechSoup provides links to recycling and refurbishing resources that accept computer donations: www.techsoup.org/recycle/donate.
Buy green
If you’re in the market for a new PC, do some research before you buy: many computer manufacturers, including Dell, HP, Acer, and others, now offer “green” models that use less energy, have more reusable/rechargeable components, or use recycled material.
And your best bet may be to choose a laptop over a desktop. In order to optimize battery usage, most laptops have energy-efficient features built-in: a laptop can use up to 50% less electricity than a desktop machine.
