This authoritative but highly accessible book presents the reader
with a powerful framework for understanding the critical role of
the energy return on investment (EROI) in the survival and
well-being of individuals, ecosystems, businesses, economies and
nations. Growth and development are fundamental and ubiquitous
processes at all scales, from individuals to food crops to national
economies. While we are all familiar with the concepts of economic
growth and living standards as measured by gross domestic product
(GDP), we often take for granted the energy use that underpins GDP
and our expectations for year-on-year growth. In this book, you
will learn how these measures of "progress" are completely
dependent on the balance that can be achieved between energy costs
(inputs) and gains. Nothing is made or moved without an energy
surplus, and it is the EROI of available energy sources more than
any other single factor that determines the shape of civilization.
Nearly all politics and economics assume that policy and market
forces are the levers upon which future outcomes will hinge.
However, this book presents many examples of historical and current
events that can be explained much more clearly from an energetic
perspective. In addition, a future scenario is developed that gives
a central place to EROI in assessing the potential of governmental
and private initiatives to substitute so-called renewable energy
sources for diminishing stocks of fossil fuels. When cheap fossil
fuels are no longer available in the abundance needed to mask
economic problems and power business as usual, it will be EROI more
than the plethora of "green" technologies that creates the boundary
conditions for a sustainable future.
