"Power Shift's breakthrough insight is that human civilization has embarked on a great transformation from static fossil energy to dynamic solar power, altering the basic relationship between humans and energy. This shift is so fundamental that it defines a new historical epoch, and looms as large as the discovery of fire, the development of agriculture, and the exploitation of fossil fuels. Today few are aware that this new epoch has already begun. Written for a general audience, Power Shift explains this insight by retelling the story of humans in terms of energy. It shows how energy defined our species and supported our expansive takeover of Planet Earth. It clearly outlines our current energy dilemma, and the way forward."--
