“A revelatory look at our national power grid—how it developed, its current flaws, and how it must be completely reimagined for our fast-approaching energy future. America’s electrical grid, an engineering triumph of the twentieth century, is turning out to be a poor fit for the present. It’s not just that the grid has grown old and is now in dire need of basic repair. Today, as we invest great hope in new energy sources—solar, wind, and other alternatives—the grid is what stands most firmly in the way of a brighter energy future. If we hope to realize this future, we need to reimagine the grid according to twenty-first-century values.”
