This is a guest post by TOD reader Jon Friese. Jon is a software engineer living in Minneapolis and a volunteer with the Twin Cities Energy Transition working group, seeking a path to a low carbon future. Under his own initiative Jon tracked down literature on EROI methodology, contacted the Canadian Government and an energy consulting company for data, and came up with the following analysis on declining energy return on Canadian Gas. This draft analysis is provocative (backing into an EROI estimate using $/GJ suggesting possible energy break even for natural gas within a decade). However, in addition to the new info, I was inspired that a smart, engaged citizen chose to volunteer his time on the pressing issue of fossil fuel decline, and then shared it with others in the TOD forum for feedback. Thanks for your initiative here Jon.) (Editors Note: Jon is working on an update to this analysis incorporating feedback from the TOD community -please treat the information in this post as a work in progress.)
