Abstract: Dickinson College just finished a month-long energy challenge where the goal was to reduce the college's energy use by 10% over the entire month compared to the previous year. Come and see how some common-sense planning and modern construction techniques helped a local family reduce their energy consumption by approximately 90% annually.
