The Very Hungry City

The Very Hungry City : urban energy efficiency and the economic fate of cities by Austin Troy (Yale University Press, 2012).

The premise of this book is that as the cost of energy goes up permanently (due to climate change and exhaustion of fossil fuel supplies), cities that use significantly more energy will lose economic competitiveness to better-designed, more energy efficient cities. Troy doesn’t explore the more radical possibility that the cost of energy could go up so much that cities would become economically isolated. However, he does make a pretty good case that energy efficiency (defined quite broadly to include water supply and public transit) is going to be a major factor in economic success of cities in the rest of this century. He provides some interesting historical background on how transit systems developed (or were not developed) in major metropolitan areas of the U.S., and the issues around suburban sprawl. Troy also offers some comparisons to urban planning approaches in Europe, particularly Sweden and Denmark, where he interviewed bicycle commuters and residents of impressive planned urban housing developments. Throughout the book Troy highlights ideas that reduce urban energy costs (tree planting, congestion pricing, LEED architecture) as examples of what the more successful cities are doing right.
