Two new books reflect on how the cartographies of power are being redrafted in the twenty-first century. As Yifei Li and Judith Shapiro demonstrate in China Goes Green, the emergent map is being dominated by an increasingly confident China, which is using an environmental platform to help to justify authoritarian rule at home and abroad. Meanwhile, Daniel Yergin delineates his own structures in The New Map by following the contours of geo-physical power: oil, gas, coal and solar.
