There are nearly one million fluorescent and incandescent lighting fixtures on campus, and the majority are fluorescent fixtures in buildings.  In 2008, the majority of these fixtures were the T12 style, which are no longer produced.  The new T8 fixture is thiner and much more energy efficient.  To replace all the T12s with T8s will take many years and millions of dollars.  However, the energy savings are great, with each replacement bulb dropping the energy demand from 40 Watts to 28 Watts.  This program has been ongoing for a number of years, and has had funding support from a variety of sources.  Work is continuing to occur this year.
