Sustainable Energy Calendar As of July 2007, this page is no longer regularly updated - the Sustainable Energy Calendar has migrated to the CIGoGreen website, www.cigogreen.org, which offers a more user-friendly (and maintenance-friendly) format. The calendar still features lectures, public hearings, workshops, tours, classes, and other activities relating to energy supply and use, illustrating the many connections with economic, environmental, and social issues. If you would like to add an event, send information to feedback@cirenew.info. For events prior to July 2007, visit the Calendar Archive.

Dirty Roof

Conventional asphalt shingles are
the cheapest roofing material around but, as is usually the case, there is a cost: They are manufactured using petroleum by-products and, once they reach the end of their useful life, they must be landfilled as construction debris or “downcycled” as road materials or in other low-value uses.
