What a great book. It's been a while since I finished it, but I realize that I didn't write a summary for it. Basically, he addresses the whole climate change issue in this follow up to The World is Flat. He talks mostly about building a market climate condusive to innovation in the green sector by providing price certainty for oil. He also addresses maintaining biodiversity, and improving user efficiency through both product design and power grid. His main solution is just to make market signals for innovation that will seep into the rest of our economy. Another aspect of his proposal was the implementation of a smarter, more effcient grid. Like I said, very good read.
