A Calvin College engineering professor and six students presented a seminar on wind energy to a very special guest on Tuesday, February 20, 2007 at the college's Bunker Interpretive Center. Michigan governor Jennifer Granholm, who has made alternative and renewable energy a focus for her administration, sat front and center as professor Matt Heun and his students walked Granholm through recent Calvin efforts to harness the power of the wind, including a grant from the state of Michigan to install a demonstration turbine on Calvin's campus.
