I’m not popular with environmentalists when I tell them that renewables can only provide a small fraction of the energy that fossil fuels do in powering industrial civilization. In fact, I was recently called a liar at the screening of an anti-nuke film for suggesting so.
This note aims at exploring the scientific foundations and therefore the scope of validity of these forecasting techniques. Looking at the basic assumptions of Hubbert’s thesis, it concludes that these techniques should not be used to forecast neither the peak (or plateau) of the annual production rate, nor the ultimate reserves of any mineral, unless given exceptional conditions.
In 2006 I began a book that traced the relationship between flowers and the human imagination, those circular and winding tracks that are buried deep inside. It’s a record of a 10 year exploration into the linguistics of wild medicinal plants and a description of a practice I developed with Mark that began with some questions: Can we enter the flower’s territory on its own terms, beyond our monocultural control of the “environment”? What effects do their fragrance, their medicine, their shapes have on our imaginations, on our memories? How do they enter our dreams?
Current climate and energy policy debates in the United States rarely involve historians. If you search the Intergovernmental Panel on Climate Change’s 2007 synthesis report, you will not find the words history or historical. Even so, history pervades climate and energy policy discussions. History guides policy choices, inspires proposals for action, and structures institutional development.
Most discussions of the future of electric power start from the assumption that maintaining a grid of the modern kind, designed from top to bottom around ample supplies of cheap fossil fuels, is the only option there is. It’s long past time to revisit that notion. Are our current ways of electricity production, distribution, and use merely the extravagant habits of a temporary age of excess, and what might an appropriate system for producing and using electricity look like in an age of scarcity?
In a new book, Charles Saylan, co-founder and executive director of the California-based Ocean Conservation Society, and his co-author pose a key question: What can the U.S. educational system do to improve students’ understanding of the environment and its importance in their lives?
Ever since the arrival of fossil fuels and electricity, human powered tools and machines have been viewed as an obsolete technology. This makes it easy to forget that there has been a great deal of progress in their design, largely improving their productivity.
CSE’s view is that wind power is a necessary part of the energy mix that is required to meet our carbon emission reduction targets and help tackle climate change. However, wind power is not appropriate everywhere, and we believe it is the duty of local communities themselves to decide where there is a place for it through engaging responsibly with the best available evidence, and through working together to assess their own locality.
Elites in both corporations and government are often quite good at running systems they create, and bad at looking beyond these systems at larger social effects.
The energy descent from peak oil production imposes decades of contraction in the global economy. An orderly contraction, particularly in the US, is not likely for a number of reasons. The decline of the oil civilization is a phenomenon and spectacle of such complexity that understanding it requires a systems perspective. This summary of the case for a disorderly contraction and its core drivers demonstrates the capacity of systems tools to show the interlocking feedback structure that shapes how this momentous change plays out over time.
In pondering the reasons for this lack of progress—this potentially cataclysmic failure of progressive argument—I have come to a fairly radical view: that we can never have a sustainable civilization unless we first achieve sustainability as individuals. Billions of us (not just a few million) will need to embrace lower-consumption, more thoughtful, more ecologically conscious lifestyles with the same personal passion that is today wasted on free-market profiteering, religious proselytizing, or yearning for power and control of other humans. And if I had to identify the single most daunting barrier to that kind of embrace, it is our pervasive intellectual and emotional disconnection from the living planet we evolved on.
