A theoretical framework to study the economic importance of energy

Benjamin Leiva PhD Student University of Georgia Athens, GA, United States Abstract Using marginal analysis, we develop a theoretical framework to study the economic importance of energy without considering it a factor of production. Instead, for an autarkic agent, energy is considered a constraint in consumption and an objective in production. Despite such roles, which are meaningfully justified, the framework implies that power —and not energy— is generally the limiting res

The Biophysical Economy and Central Bank Risks

Nicholas Walldorff Chief Information Officer Covington Investments, LLC Atlanta, GA Abstract The modern central banking system is responsible for many activities including payment settlement and regulatory oversight of the modern financial system. Central bank policy seeks to optimize macro economic output around certain unique mandates however control over the economy is limited. Currently a prevailing mandate among central bank institutions is the objective of “price stabil

Examining The Relation between Quality of Life and Biophysical vs Economic Conditions

Jessica Lambert Chief Information Officer Next Generation Energy Initiative Marcellus, NY Abstract In a previous paper (Lambert et al. 2014) we examined the link between declining EROI and quality of life indicators for average citizens within a select group of societies and found that EROI is correlated with standard of living; suggesting that decreasing net available energy adversely impacts the standard of living of an average citizen. This work extends the analysis of thi

The need for, and a plan for, a biophysical analysis of the Mexican economy

Salvador Peniche Professor University of Guadalajara Mexico Abstract The presentation explores the importance of petroleum in the development of Mexico. Special emphasis is made on the economic aspects of development, but also we analyze the impact of petroleum exploitation in population growth, land use change, and public health. We argue that the new reality of Mexico's oil situation inevitably leads us to the need to understand the relation of less cheap oil to all things

Jevons’ Paradoxes

Kent Klitgaard Professor Wells College Aurora, NY Abstract In 1865, at the behest of the British Association for the Advancement of Science, British economist William Stanley Jevons published The Coal Question. In this work, he raised many issues familiar to contemporary biophysical economists. The maintenance of British prosperity and industrial power depended upon the expansion of heavy industry, which itself depended upon an increase in the scale of coal production. For Je

Hubbert linearization: a "new method to estimate petroleum reserves and its applications to U.S.

Charles A. S. Hall Professor Emeritus SUNY - Environmental Science and Forestry Syracuse, NY chall@esf.edu Abstract Hydraulic fracturing for shale (tight) oil in the United States, commonly known as “fracking,” has postponed (or extended) the global peak of oil, and, for some, discredited the concept of “peak oil”.  The multi-trillion dollar question for the global economy is for how long will this “revolution” in unconventional oil (and gas) last?  Official government and in

A Biophysical-Economic Framework for Understanding Collapse in Modern Society

David Murphy Assistant Professor of Environmental Studies St. Lawrence University Canton, NY dmurphy@stlawu.edu Abstract Energy and food represent essential items for complex societies, as energy is required to maintain societal function – i.e. the societal metabolism – while food is required to feed the population. Deficits in either one of these categories can quickly lead to destabilized societies. Modern societies utilize globalization and trade to survive, and in some ca

A Long-Term Growth Model with Endogenous Biophysical and Economic States

Carey King Research Scientist & Assistant Director University of Texas at Austin Austin, TX, 78712-1718, United States careyking@mail.utexas.edu Abstract Long-term economic growth models often assume that energy resources and technology are not constraints on the economy. Energy transition scenario models often assume that economic growth will not constraint an energy transition. Both types of models often neglect fundamental dynamics and the influence of debt and subsequent

A world tour of farm systems in light of biophysical economics

Solis Norton New Zealand Abstract The global primary food production system needs reconfiguring over the next 25 years to feed a growing human population under increasing resource constraints, energy in particular.  Drivers of this reconfiguration are very different from food production drivers of the last 25 years. Nuffield agricultural scholarships enable recipients to travel widely and learn from food production experts around the world. Through March and April 2018 our gr

Spruce budworm and oil price: a biophysical analogy

Luciano Celi, Claudio Della Volpe, Luca Pardi, Stefano Siboni University of Trento – Italy Abstract The behavior of complex systems is one of the most intriguing phenomena investigated by recent science; natural and artificial systems offer a wide opportunity for this kind of analysis. The energy conversion is both a process based on important physical laws and one of the most important economic sectors; the interaction between these two aspects of the energy production sugge

MODELING THE LONG TERM ENERGY FUTURE

Jim Case Abstract It is generally assumed that wind, solar, and other renewable sources will render energy as abundant and affordable in the future as it has been in the recent past. Yet existing wind and solar farms have all been constructed with the assistance of fossil fuels, raising the possibility that it will no longer pay to replace them when fossil fuels have been exhausted. The question is addressed within a moderately comprehensive ― and therefore dynamic ― biophysi

Biofuel Technology and Innovation in the 21st century

Michelle Arnold Graduate Student Utah State University Logan, Utah, United States Abstract Innovation is a key element in the belief of infinite economic growth. With consistent or increasing innovation, economies are able to use resources more efficiently and thus combat the consequences of increasing scarcity. However, it has been shown that when investigating innovation that the theory of diminishing returns does apply within multiple fields and industries. Over the past s

Energy Return on Investment of “living off the land”: natural production, human labor, and petroleum

Stephen M. Coghlan Jr. Associate Professor University of Maine Orono, ME, United States Abstract As projected by Limits to Growth and other biophysical analyses, economic shocks from resource depletion, pollution, and debt overload threaten our current standard of living. The prospect of ecological overshoot and impending economic decline has motivated some people to find alternate means to produce economic surplus, increase their self-sufficiency, withstand climate disruptio

Impact of agricultural production systems on the energy efficiency of agro-bioenergy systems

Oludunsin Tunrayo Arodudu Postdoctoral researcher Maynooth University Ireland Abstract In light of possible future restrictions on the use of fossil fuel, due to climate change obligations and continuous depletion of global fossil fuel reserves, the search for alternative renewable energy sources is expected to be an issue of great concern for policy stakeholders. This study assessed the feasibility of bioenergy production under relatively low-intensity conservative, eco-agri

Achieving provisioning, regulating, supporting, and cultural ecosystem services in agricultural land

Christina Tonitto Research Associate Cornell University Ithaca, NY, United Abstract Agricultural landscapes comprise approximately 50% of global habitable land cover. Maximizing yield is often the dominant goal in agricultural landscapes. Given the extent of agricultural lands, it is important to manage agricultural landscapes to produce a range of ecosystem services. Agroecological approaches to food production balance crop yield with support for: 1) nutrient cycling and ret

Insights Regarding the Operation of the Energy-Economy

Gail Tverberg OurFiniteWorld.com Abstract This presentation lays out insights into how the economy operates as a self-organized system powered by energy. There is a physics problem involved, but it is not the same physics problem that people in the 1970s thought was the case. Most systems in the universe behave like energetically open systems. They tend to grow and change over time. None of them are permanent. The economy is such a system. There are many other such systems (i

Resource productivity in theories of cost-share induced technological change

Eric Kemp-Benedict Senior Economist Stockholm Environment Institute Abstract The prospects for long-term sustainability depend on whether, and how much, we can absolutely decouple economic output from total energy and material throughput. While relative decoupling has occurred—that is, resource use has grown less quickly than the economy—absolute decoupling has not, raising the question whether it is possible. This paper proposes a novel explanation for why decoupling has not

The Modern Global Financial System Is an Ecosystem

Garvin Boyle Independent BPE Researcher Orrery Software Ontario, Canada Abstract This presentation will outline an argument that the modern global financial system is, in fact, a new kind of ecosystem in its own right, and not just an analogy of one.  It is an ecosystem of a slightly different form – a hybrid biophysical and logical ecosystem constrained by additional laws that do not constrain the well-known biological ecosystems.  Based on a paper by Boulanger and Bréchet,

What Drives Urban Sprawl in the United States: Rising Population or Falling Population Density?

Leon Kolankiewicz Senior Environmental Scientist Environmental consultant to NumbersUSA State College, PA Abstract To neoclassical economists, urban sprawl represents economic growth and dynamism. To ecologists, in contrast, it represents unsustainable, environmentally-damaging appropriation and displacement of critical natural ecosystems. In biophysical terms, sprawldegrades or eliminates natural habitats and their ecological services as well as productive agricultural land

The Pathway for Biophysical Economics

Feng Lianyong Professor China University of Petroleum, Beijing China Abstract The discussion on the limitations of the mainstream economic theory has lasted for so long. Especially after finical crisis in 2008, more and more people began to criticize traditional economics and tried to establish some new theories. Biophysical economics is one of the most possible theories to replace the traditional economics. It should be admitted that the biophysical economics has achieved gr
