Query: We need to solve it

This book "gets it". There is a crisis. We need to end our dependency on oil.The book also undestands that this will best be solved by economics. Some people will pay a bit more to "feel good" and "save the world" but a whole lot more will do it if it saves money.I am an optimist and like the optimisitic view the book takes. I worry though that policy that pushes economics to solve this issues might get delayed due to special intereste.Interesting, thought provoking book.
