Friedman proposes that an ambitious national strategy - which he calls "Geo-Greenism"- is not only what we need to save the planet from overheating; it is what we need to make us all healthier, richer, more innovative, more productive, and more secure. As in "The World Is Flat", he explains a new era - the Energy-Climate era - through an illuminating account of recent events. He sets out the clean-technology breakthroughs the world will need; he shows that the ET (Energy Technology) revolution will be both transformative and disruptive; and he explains why America must lead this revolution.
