Feasta Tipping Point Report and the New Emergency Conference


Feasta aims to identify the characteristics (economic, cultural and environmental) of a truly sustainable society, articulate how the necessary transition can be effected and promote the implementation of the measures required for this purpose.

Feasta has released a new report Tipping Point: Near-Term Systemic Implications of a Peak in Global Oil Production, by David Korowicz of Feasta and the Risk/Resilience Network, is now available for download. The report argues that the defining dynamic of our civilisation is the withdrawal of energy from a complex and integrated system adapted only to growing. A managed "de-growth" is impossible; what is required is rapid emergency planning coupled with a plan for longer-term adaptation.

Feasta organized The New Emergeny Conference last year. The videos of all of the presentations from the conference can now be viewed for free on the conference website.

This conference, marking Feasta's tenth anniversary, analysed the systems and the mindsets that have steered the world onto its grotesquely unsustainable current path. Discussions focussed on the new systems (financial, energy, food) and ways of thinking that are urgently required to correct the situation and bring about a rapid transition to a more secure future. Many of the ideas explored were Feasta's. Others were presented by international speakers who broadly share Feasta's analysis of what needs to be done to build a truly sustainable world.

That's it for the 100th post on the Energy Crash blog.

Environment, power, and society for the twenty-first century



"Get a rare, fresh, enlightening glimpse of the Big Picture of our environmental and energy problems - Highly recommended." -- Choice

Howard T. Odum possessed one of the most innovative minds of the twentieth century. He pioneered the fields of ecological engineering, ecological economics, and environmental accounting, working throughout his life to better understand the interrelationships of energy, environment, and society and their importance to the well-being of humanity and the planet.

Environment, Power and Society for the Twenty-First Century: The Hierarchy of Energy is a major modernization of Odum's classic work on the significance of power and its role in society, bringing his approach and insight to a whole new generation of students and scholars. For this edition Odum refines his original theories and introduces two new measures: emergy and transformity. These concepts can be used to evaluate and compare systems and their transformation and use of resources by accounting for all the energies and materials that flow in and out and expressing them in equivalent ability to do work. Natural energies such as solar radiation and the cycling of water, carbon, nitrogen, and oxygen are diagrammed in terms of energy and emergy flow. Through this method Odum reveals the similarities between human economic and social systems and the ecosystems of the natural world. In the process, we discover that our survival and prosperity are regulated as much by the laws of energetics as are systems of the physical and chemical world.


The Book Environment, Power and Society for the Twenty-First Century: The Hierarchy of Energy is available on Google Books with limited preview.

Climax and Descent (Chapter 13)

The growth of civilisation on the nonrenewable reserves of the earth is surging to a climax of information miracles, stormy economics, turbulent populations, concentrated wealth, and bewildering complexity. Although the future is always masked by the oscillations of smaller scale, the empower of society may be at climax in transition to times of receding energy. This last chapter uses principles of energy hierarchy and pulsing to anticipate the future, suggest adaptive policies, and seek a prosperous way down.

...

By developing explanations and plans now for making descent prosperous, we can be ready when the shocks of change galvanize the attention of society. Some can have faith in the future from understanding energy principles. Other will find faith in religions that adapt the necessary commandments for once again fitting culture to the earth. The people of Easter Island disappeared, leaving only their monuments as an example to the world of what happens when culture cannot downsize to fit its environmental production.

Publications by the new economics foundation


nef (the new economics foundation) is an independent think-and-do tank that inspires and demonstrates real economic well-being.

Growth isn't Possible

Four years on from nef's Growth isn’t Working, this new report goes one step further and tests that thesis in detail in the context of climate change and energy. It argues that indefinite global economic growth is unsustainable. Just as the laws of thermodynamics constrain the maximum efficiency of a heat engine, economic growth is constrained by the finite nature of our planet’s natural resources (biocapacity).

The Cuts Won't Work

Why spending on a Green New Deal will reduce the public debt, cut carbon emissions, increase energy security and reduce fuel poverty.

The Great Transition

Creating a new kind of economy is crucial if we want to tackle climate change and avoid the mounting social problems associated with the rise of economic inequality. The Great Transition provides the first comprehensive blueprint for building an economy based on stability, sustainability and equality.

The Consumption Explosion

Overconsumption, not overpopulation, is the real threat to the environment. Even the recession has had little impact on our burgeoning ecological debt.

Ecological Debt

This book explores a great paradox of our age: how the global wealth gap was built on ecological debts, which the world's poorest are having to pay for.

A Green New Deal

The global economy is facing a ‘triple crunch’: a combination of a credit-fuelled financial crisis, accelerating climate change and soaring energy prices underpinned by encroaching peak oil. It is increasingly clear that these three overlapping events threaten to develop into a perfect storm, the like of which has not been seen since the Great Depression, with potentially devastating consequences.

Hooked on Oil

How fossil fuel profits could be taxed to fund a clean energy economy.

Economic Dynamics - And the Real Danger

George Mobus has published a new summary paper on his blog Question Everything that he have written to explain the findings from his computer model of an abstract economy's dynamics when it is run mostly on fixed, finite fuel sources such as fossil fuels.

His model describes an abstract economy in which work processes use energy and raw materials to produce assets, some of which are consumed by processes that constitute the major body of the system, some of which will be reinvested in the work processes.

The dynamics of asset production and decay are governed by the laws of thermodynamics. The general conservation law applies to both matter and energy. But the second law, in particular, has ultimate influence over the efficiency and effectiveness of work processes as well as the entropic decay of all forms of assets.

A key question that needs to be addressed is: given our current heavy reliance on fossil fuels for more than 80% of our energy inputs, what happens in an economy that is growing when the resources are depleting?


Many people have realized, either intuitively or logically, that what matters insofar as economic activity is concerned is the net energy — the energy available after extraction of the gross energy (in this case crude oil) and refinement or conversion to a form useful in doing work. Energy must be reinvested in energy extraction, transportation, and refinement in order to gain net energy that can be available for asset production (other than assets needed for energy extraction). Thus there is an energy return on energy invested (EROI or EROEI) that must be taken into account in determining if an economy is viable, stable, or growing.
