Eleven undergraduates from around the U.S. are performing research this summer on renewable energy technologies as part of Research Experience for Undergraduates. Their projects range from solar power system sizing to green roofs to biomass. The campus community is invited to attend a symposium highlighting the students’ research from 1 to 5 p.m. Friday, July 26, in St. Pat’s Ballroom C of the Havener Center. Light refreshments will be served.
