The National Resource Defense Council (NRDC) and the Green Sports Alliance has named Arizona State University's Sun Devil Athletics a top 10 athletic department working towards sustainability. "Progress toward sustainability requires the reconceptualization and reorganization of all of university enterprises," said ASU President Michael Crow. "Nowhere is this more visible than in athletics, where the interaction between the university and its constituents is most public." Sun Devil Athletics has nine athletic-specific solar installations that generate about 7.5-megawatt hours of electricity each year, the most of any university athletic department in the country. The nine solar power systems are part of ASU's current 72 collective systems across all four campuses.
