Susan Spencer is finishing her Ph.D. at RIT, and some day soon, she could be part of a team that brings a scalable solar energy plan to Rochester. Last month, she was one of 500 people from around the world chosen to attend Al Gore's foundation retreat in Melbourne, Australia. The five-day event was focused on two things: 1) the true cost of carbon, and 2) how to better communicate climate change. It culminated with an eight-hour lecture from Al Gore himself. In this hour, she tells us what she learned, and how solar might be the energy source everyone has been looking for.
