We all know it : energy – and resource – efficiency is the panacea to all our energy and environmental woes. As I finished reading another excellent book on the very matter, I am sharing with you today the main findings. Factor Five is the sequel of the 1997-book Factor Four. It demonstrates how our …
One of my previous posts was useful as an answer to a discussion on CleanTechies, so I decided to repost it there : ” It has been previously stated here in an article by Crisp Green that generating energy from poop is unlikely. “ ” I disagree. It seems that the idea is not too …

With molten salts, concentrating solar could bring light to these populations during important parts of the night. Solar cookers could also help fighting deforestation by removing the need for fuelwood. Now an experiment run in Benin (West Africa) shows …
This is the catchy title of an article GOOD recently published. It is not entirely new to me as I previously wrote about it, but the data provided there undoubtedly has to be shared. Here goes the beginning of the article : ” When it comes to food, Americans are the undisputed champions of one …
