The U.S. government could save up to $370 million a year by
switching fonts, from Times New Roman to the thriftier Garamond
according to 14-year-old high school student Suvir Mirchandani. 
Update: It seems there are some flaws in Mirchandani's theory,
which you can read about here. The font switch, while clever,
many not make much difference after all.  Speaking on
HuffPostLive, Mirchandani explained that he first came to study
cost-saving fonts as a means of reducing the resources used in
his middle school:   I thought about paper and I thought about
ink. For paper, we have these paper recycling programs, dual-
sided printing, all to reduce paper cost and paper use. But on
the other hand there's ink. I haven't really heard about much to
conserve ink use -- and it turns out that ink costs almost six
times as much as paper does. So I thought it would be really
interesting to see a project that could reduce ink use. I also
noticed that some fonts use more ink... so I decided to look
into that for my science fai
