The world is about to run out of cheap oil and change dramatically. Within the next few years, global production will peak. Thereafter, even if industrial societies begin to switch to alternative energy sources, they will have less net energy each year to do all the work essential to the survival of complex societies. We are entering a new era, as different from the industrial era as the latter was from medieval times. In this book, Richard Heinberg places this momentous transition in historical context, showing how industrialism arose from the harnessing of fossil fuels, how competition to control access to oil shaped the geopolitics of the 20th century, and how contention for dwindling energy resources in the 21st century will lead to resource wars in the Middle East, Central Asia, and South America. He describes the likely impacts of oil depletion, and all of the energy alternatives.
Predicting chaos unless the US - the world's foremost oil consumer - is willing to join with other countries to implement a global program of resource conservation and sharing, he also recommends a 'managed collapse' that might make way for a slower-paced, low-energy, sustainable society in the future.
