UT Austin's power plant supplies almost 100% of the power and thermal requirements for over 20 million square feet serving 70,000 faculty, students and staff. Energy management efforts have enabled UT Austin to hold fuel consumption equivalent to 1977 levels while campus doubled in gross building space. The Hal Weaver Power Plant has won several international awards for efficiency and was recently recognized as the first in the world PEER: Campus.
In 2011, the Natural Resource Conservation Plan set a goal of reducing demand side energy consumption at the building level by 20% per square foot by the year 2020 using 2009 as the base year. The plan was updated in 2014. Currently, 16.6% energy reduction has been achieved via technical efforts and campus engagement.
UT Austin has installed just over 500 kw of solar photovoltaic arrays on the main campus, almost all in support of research initiatives. A 2 million btu solar thermal array on the NHB building is the largest of several thermal arrays. In 2015, the university began buying Austin Energy GreenChoice power for 10% of the demand at the Pickle Research Campus.
