The University at Buffalo is the 11th largest user of green power among U.S. colleges and universities, according to the U.S. Environmental Protection Agency. That's up from 14th in last year's ranking.
The university bought more than 44 million kilowatt hours of green power in the 2011-12 academic year, representing 20 percent of its annual electricity usage.
That rose to 77 million kilowatt-hours in 2012-13, about 35 percent of UB's power use.
UB credited the jump to the purchase of EPA renewable energy certificates that subsidize clean energy projects such as wind turbines and power plants fueled by biomass. Other steps have included the university's Solar Strand, which includes 3,200 photovoltaic panels, and a series of environment-friendly programs such as bicycle-sharing, composting food waste and building or renovating facilities that are eco-friendly.
UB has set a goal of being climate neutral by 2030, which involves eliminating or offsetting the emission of greenhouse gases. The full list of the top 20 green energy users among U.S. colleges and universities can be found through a link at
