Use Less Ink?

My friend Kate recently sent me this news

The University of Wisconsin-Green Bay is actually making headlines this week by switching the font it uses in its emails. The school says that printing out documents in Century Gothic rather than its old font, Arial, uses 30% less ink.The move is part of the school’s five-year plan to go green — and save money. Printer ink costs about $10,000 per gallon.

The article then asks “But there’s just one problem: Who prints emails from colleges?” I guess I agree, but read the entire article here.
And see below to see the visual difference between the 2 fonts:

Arial vs. Century Gothic
