Special Section Editorial: Risk, Complexity And Sustainability, Lindsay Robertson, Katina Michael

Professor Katina Michael

This special section is dedicated to risk as understood within our society, in which we depend upon increasingly complex and interconnected technologies for even our most basic needs - water, food, shelter, electricity, gas, sewage, communications, and banking.

Natural disasters and their impact on vital services has been a research area that has flourished, especially since the 2004 Indian Ocean Tsunami that claimed hundreds of thousands of lives in South Asia. Out of this research has come forth a plethora of strategies for addressing short term and geographically defined disasters. While such disaster preparedness systems are vital to minimise the …

Accelerating Applied Sustainability Of Utilizing Return On Investment For Energy Conservation Measures, Joshua Pearce, D. Denkenberger, H. Zielonka Dec 2008

Accelerating Applied Sustainability Of Utilizing Return On Investment For Energy Conservation Measures, Joshua Pearce, D. Denkenberger, H. Zielonka

Joshua M. Pearce

Many energy conservation measures (ECMs) that utilize energy more efficiently thanstandard devices or practices will save money in the long term; however, decision makers oftenfail to deploy ECMs because of what is viewed as a prohibitively long payback time. This paperprovides a graphical tool to determine the return on investment (ROI) of any ECM from only thesimple payback and device lifetime, which corrects this common economic error. Utilizing thismethod will encourage the increased deployment of energy efficiency and renewable energytechnologies, while improving the economic performance of the companies and individuals thatutilize the method.
