The university has joined Clean Air Counts, a Chicago-based coalition of schools and businesses committed to reducing emissions by five tons per day. U-Chicago has fulfilled a portion of its energy needs by purchasing wind energy since 2004, and facilities services funded a new unit, the Department of Energy and Utilities Management, in 2006 in order to develop more sustainable approaches to both supply- and demand-side energy management. Various student initiatives, such as Battle of the Bulbs and the Uncommon Turbine Project, have focused campus attention on conservation.
