"Green Tips" for your office.

You spend most of your time at work, so help make sure your office is green by following these tips.

Tip #1: Be bright about light.
Artificial lighting accounts for nearly half of the electricity use in office buildings, so turn off the lights whenever you leave any room -- and invite in natural light wherever possible. Make it a policy, too, to buy Energy Star-rated lightbulbs and fixtures, which use at least two-thirds less energy than regular lighting, and install timers or motion sensors that automatically shut off lights when they're not needed.

Tip #2: Maximize computer efficiency.
Computers in the business sector waste $1 billion worth of electricity per year, so make it a habit to turn off your computer -- and the power strip it's plugged into -- when you leave work for the day. Otherwise you'll still be burning energy even if you're not burning the midnight oil. During the day, setting your computer to go to sleep during short breaks can cut energy use 70%. Remember, screen savers don't save energy.

Tip #3: Print smarter (or not at all).
The average U.S. office worker can use 10,000 pieces of copy paper per year. To reduce your number, print double-sided whenever possible. Avoid color printing (hues are more likely to be toxic) and consider downloading Ecofont to save ink. Better yet, really think about whether you need that information down on sheets of dead trees, or whether having it on your computer is good enough.

Tip #4: Chew on this.
Much of your munching happens at the office, so keep your own mug, dishware, and flatware at your desk. This will fend off the temptation to use the paper and plastic disposables that are easy to grab in the lunchroom. If you're a workplace manager, provide reusable dishes, silverware, and glasses. Switch to eco-friendly coffees and teas, and buy organic and local food for parties and other events. And remember: Water fountains are always better than bottled water.
