Recently, a student posted paper fliers on several engineering school flat screens, decrying the technology for wasting money and energy. The fliers were summarily removed twice, but it’s apparent that the point did not go unheeded: The engineering school has since limited the hours that the flat screens are turned on to 8 a.m. to 6 p.m. on Monday through Friday.

Following a silent demonstration from an anonymous party, the Washington University School of Engineering and Applied Science has pledged to cut down the amount of time it operates several flat-screen televisions in its buildings.
