Carbon civilisation is powered predominately by finite fossil fuels and with each passing day it becomes harder to increase or even maintain current supply. Our one-off fossil energy inheritance is but a brief anomaly in the evolution of the human story, a momentary energy spike from the perspective of deep time. Today humanity faces the dual crises of fossil fuel depletion and climate change, both of which are consequences of the modern world's fundamental reliance on the energy abundance provided by fossil energy sources. Can renewable energy replace the fossil energy foundations of carbon civilisation? This book examines these issues and presents a narrative linking energy and society that maintains we should be preparing for renewable futures neither of energy abundance nor scarcity, but rather energy sufficiency. For industrial societies, this means navigating energy descent futures.

Life Beyond This Brief Anomaly

Carbon Civilisation and the Energy Descent Future

Graham Palmer

Fossil fuels comprise the accumulation of prehistoric biomass that was energised by sunlight, and formed by earth system dynamics. Fossil fuels can be conceptualized as stored energy stocks that can be readily converted to power flows, on demand. A transition from a reliance on stored energy stocks, to renewable energy flows, will require a replication of energy storage by technological devices and energy conversion methods. Most analyses of energy storage focus solely on the economic-technical properties of storage within incumbent energy systems. This book broadens the scope of the study of storage by placing it within a broader, historical, biophysical framework. The role and value of storage is examined from first principles, and framed within the contemporary context of electrical grids and markets. The energy-economic cost of electrical storage may be critical to the efficacy of high penetration renewable scenarios, and understanding the costs and benefits of storage is needed for a proper assessment of storage in energy transition studies. This book provides a starting point for engineers, scientists and energy analysts for exploring the role of storage in energy transition studies, and for gaining an appreciation of the biophysical constraints of storage.
