Mark Pierce from Cornell Cooperative Extension was one of five guest instructors at last Saturday’s Energy Teach-In for twelve leaders from the Shaleshock Alliance.  The energy teach-in was hosted by Sustainable Tompkins as part of its Marcellus Challenge which aims to help local citizens reduce their demand for natural gas and fossil fuels through conservation, energy efficiency, and investment in renewable energy.  Attendees spent the day exploring options for energy savings from air sealing, insulation, elimination of phantom electrical load, and a wide variety of conservation behaviors accessible to everyone.
