Extracted is the title of a book edited by Ugo Bardi, to which I contributed and that was recently published by Chelsea Green. I had previously left a few lines describing its contents, but now an account by Ugo himself has been made available in video.
Not so clear what the methane tap is doing there, but appart from that the video is quite good. This book is an essential piece of the economical and environmental puzzle we live these days; naturally highly recommended. Beyond Ugo's remarks on the cost of source rock fossil fuel resources I'd also note the vast artificial inflation of reserve estimates uncovered recently. Certainly something not in the fix toolbox.
