Thanks to energy efficiency improvements, The University of Texas at Austin's power plant uses roughly the same amount of fuel as it did in 1977 -- yet it produces about twice the power and serves almost twice the square-footage in building space.
Over $150 million in efficiency improvements were paid for by savings from reduced fuel costs. In addition to saving the university money, increased efficiency has reduced CO2 emissions from power generation by about 100,000 tons.
"The greenest energy is the energy not used," says Juan Ontiveros, director of Utilities and Energy Management.
