This is the most informative article I've ready about renewable and non-renewable energy. Thanks for educating me. Now, I should read you book, 50 Ways To Save The World. And I will do so if (when?) it is included in the new Medium publication Free Amazon Reviews for Your Featured Book. These are "verified customer reviews" that satisfy all Amazon's requirements, and they cost you nothing. We are just beginning to list books submitted for review. They will be listed first-come-first-served, so you may want to check out the publication soon. (You need many more than seven Amazon ratings.)
