Just in time for Christmas, I see that the new book by Oudes, Stremke and Picchi to which I contributed an essay is now available to order. It will be a beautiful offering: the Europeans generally do books beautifully, but particularly so here thanks to the architects leading the project and their attention to visual detail. Edge to edge photos, maps and essays from some of the most interesting folks in Energy thinking. I am delighted to be involved and looking forward to my copy landing in October. My essay reflects on some of my early work on climax thinking and what it means for progress in energy transitions, with a few accompanying photos from case study locations in New Brunswick (the Mactaquac dam headpond) and Nova Scotia (the Tantramar outside Amherst).
