Energy Use in State Facilities Report

Wisconsin’s efforts to reduce energy consumption and costs in state-owned facilities began in earnest as a result of the rapid energy cost increases following the first Middle East oil embargo in 1973. Energy conservation and energy management efforts in state facilities have received continued support from the Governor, the State Building Commission, and the Wisconsin Legislature over the ensuing years. As testimony to the great facility managers and this support, the rate of annual energy use in state facilities has been reduced 32 percent since 1973.
