As part of the school's five-year plan to go green, msnbc.com recently reported that the University of Wisconsin-Green Bay has switched the default font on its e-mail system from Arial to Century Gothic. While the change sounds minor, it will save money on ink when students print e-mails in the new font. The new font uses about 30 percent less ink than the previous one. That could add up to real savings, since the cost of printer ink works out to about $10,000 per gallon. It's great that a change that's eco-friendly also saves money.
