Frequently the site of crisis or turmoil, individual cities can be fragile environments. For the first time in history, however, the future of the entire urban system is being thrown into doubt. Catastrophic climate changes threaten the life support of hundreds of millions, perhaps billions, of urban dwellers around the world. Supplies of fossil fuels, especially oil and natural gas, are declining worldwide. Modern cities not only depend on petroleum products for their power, but also for their goods and services - including the making and packaging of virtually all food. How might this precarious global condition be turned around? How can the energy infrastructure of cities, towns and rural settlements be restructured, to confront the environmental challenges of our time? Could a new, positive global vision emerge out of the impending, massive shift from unsustainable fuels to a renewable energy base? Opening with a definition of renewable power, the book concisely sets out the fundamental logic and philosophical framework of the urban energy revolution. It then progresses to look at how cities best attempt adaptation to accelerating, anthropogenic climate change: by mitigating it and fighting its root causes. Two central chapters map the spatial implications of the urban renewable energy transformation and the new technologies that might be involved in successfully creating the renewable city. The guide not only compares different approaches to creating renewable cities, but also examines various sustainable building assessment and design tools. The volume concludes with an easy to use best-practice template for local governments and planners, applying lessons from advanced cities around the world
