Richard Heinberg writes: You are no doubt keenly aware that the economy is and will be the matter of overwhelming concern for the coming year (or years), for policy makers as well as for most nearly every individual and family. Following this current project, my research and writing will be devoted to identifying strategies that can help families and communities adapt to the new economic conditions while laying the groundwork for a truly sustainable society.
This report is intended as a non-technical overview of the prospects for known energy sources to supply society’s energy needs at least up to the year 2100. … It shows why energy conservation (using less) and humane, gradual population reduction must be key strategies to achieving sustainability.
The world’s current energy regime is unsustainable. This is the explicit conclusion of the International Energy Agency, and it is also the substance of a wide and growing public consensus ranging across the political spectrum. One broad segment of this consensus is concerned more about the climate impacts of society’s reliance on fossil fuels; the other is moved more by questions regarding the security of future supplies of these fuels—which, as they deplete, are increasingly concentrated in only a few countries.
To say that our current energy regime is unsustainable means that it cannot continue and must therefore be replaced with something else. However, replacing the energy infrastructure of modern industrial societies is no trivial matter. Decades have been spent building the current oil-coal-gas infrastructure, and trillions of dollars invested. Moreover, if the transition from current energy sources to alternatives is wrongly managed, consequences could be severe: there is an undeniable connection between per-capita levels of energy consumption and economic well-being (see Robert Ayres and Benjamin Warr, Two Paradigms of Production and Growth). A failure to supply sufficient energy, or energy of sufficient quality, could undermine our global economic future.
It is a commonly held assumption that alternative energy sources capable of substituting for conventional fossil fuels are readily available, whether fossil (tar sands or oil shale), nuclear, or renewable. All that is necessary is to invest sufficiently in them, and life will go on essentially as it is. But is this really the case? Energy sources have varying characteristics. And it is the characteristics of our present energy sources (principally oil, coal, and natural gas) that have enabled the creation of a society with high mobility, large population, and high economic growth rates. Will alternative energy sources perpetuate this kind of society?
While it is possible to point to innumerable successful alternative energy production installations within modern societies (ranging from small home-scale photovoltaic systems to large “farms” of three-megawatt wind turbines), it is not possible to point to the example of an entire modern industrial society obtaining the bulk of its energy from sources other than oil, coal, and natural gas. The energy transition is still more theory than reality. But if current primary energy sources are unsustainable, this implies a daunting problem. The transition to alternative sources must occur, or the world will lack sufficient energy to maintain basic services.
Thus it is vitally important that energy alternatives be evaluated thoroughly according to relevant criteria, and that a staged plan be formulated and funded for a systemic societal transition away from oil, coal, and natural gas and toward the alternative energy sources deemed most fully capable of supplying economic benefits similar to those of conventional fossil fuels.
