For starters, it's useful to self-assess whether your campus is a leading innovator on all things "green" or satisfied to remain inconspicuous in the middle of the pack. If your institution is trailing but wants to assert a leadership role in environmental stewardship, you need to get engaged to understand what it will take to catch up and how IT can be a leader, not just a contributor, to such …

United States Environmental Protection Agency: Publications

Petroleum fuels are the primary energy basis for transportation and industry. They are almost always an important input to the economic and social activities of humanity. Emergy analyses require accurate estimates with specified uncertainty for the transformities of major energy and material inputs to economic and environmental systems. In this study, the oil refining processes in Italy and the United States were examined to estimate the transformity and specific emergy of petroleum derivatives. Based on our assumptions that petroleum derivatives are splits of a complex hydrocarbon mixture and that the emergy is split based on the fraction of energy in …
