PH261 is the foundation course for the Clarion University's Sustainability: Science and Policy Program and is taught by [[User:J.M.Pearce|Dr. Joshua Pearce]].\n\nThis course is a study of the physical laws and processes that underlie environmental phenomena with a special focus on [[energy]] (mechanical, thermal and electrical). We will establish both a qualitative and quantitative understanding of the underlying physical processes. Technical, economic, and social consequences of these laws and processes will be examined to better delineate the complex decisions related to human energy use and environmental issues.\n\nThis course is being offered on the web in Fall 2007 and will utilize appropedia.org for project collaboration.\n\nThe class list can be found here: = Projects =\n\n== Environmental Songs ==\n\nTo learn the basics of wiki editing and to have a little fun we created a list of [[Environmental songs|songs with environmental themes]]\n\n== Light Emitting Diode Project ==\n\nHere is an [[LED FAQ]] to assist you in writing to the decision maker in you community.\n\n[[LED]]s are the future of lighting.\n\n=== Target Communities ===\n\nThe following is a list of communities to do LCAs on in alphabetical order.
