Life Without Oil

Life Without Oil: Why We Must Shift to a New Energy Future“A gradual contraction into more sustainable patterns of resource use is not the norm for a society that is exploiting the environment. The norm is a last-ditch effort to maintain outward displays of power, and then a sudden, and dramatic, collapse.”   That’s one of the foreboding statements with which Steve Hallett and John Wright punctuate their preview of past civilisations in the opening section of their book Life Without Oil: Why We Must Shift to a New Energy Future.

They consider we are at the peak of oil production and that we’re not facing that reality. There are late flurries to extend the discovery of further oil.  Deep sea drilling, the exploitation of the Alberta tar sands and oil shale extraction are among them, the latter two causing horrendous environmental damage. But all they will produce is a temporary delay of the decline. The authors judge that around 2015 oil production will show a clear and convincing decline, and the world will be at the beginning of the end of what they call the petroleum interval. It’s an interval that will have occupied a couple of centuries in the long history of humanity. Oil has enabled the construction of a monumental global civilisation in which we have become dependent on the increased productivity and efficiencies of scale it can provide. As it diminishes and disappears we require an energy transition which the book considers we are not geared to make in good time. We therefore face a long global economic contraction as the price of oil escalates, a sequence of economic slumps which will continue until fundamental problems of energy availability, food production, water supply and population control are sufficiently well corrected.

Listener gets serious about sea level

As I walked past the magazine stand at the supermarket this week my eye was caught by the front cover of the this week’s Listener (on sale last week). “Rising sea levels & extreme weather — why NZ needs to get serious,” it said. A cautious peek inside suggested Ruth Laugeson’s article might deserve a comment on Hot Topic so I parted with four dollars and brought it home to look more closely.  It does indeed deserve mention here if only because it’s the sort of straightforward treatment of climate change that we should be able to expect of serious journalism. Laugeson has been reading Mark Hertsgaard’s book Hot: Living Through the Next Fifty Years on Earth, which I reviewed a few weeks back on Hot Topic. Hertsgaard argues that we must plan adaptation to the now unavoidable changes at the same time as working to avoid much worse and likely unmanageable change.

Merkel’s rush to renewables

I’ve become wary of politicians’ commitments to clean energy, having been disappointed by the rapidity with which the rhetoric of leaders like Obama or Rudd loses substance when the political going gets tough. But it was hard not to pay attention to a striking article in Yale Environment 360 this week in which Der Spiegel journalist Christian Schwägerl wrote of German Chancellor Angela Merkel’s new energy policy. In March, following the Fukushima disaster in Japan, she announced an accelerated phasing out of all 17 German nuclear reactors by 2022 at the latest.

“We want to end the use of nuclear energy and reach the age of renewable energy as fast as possible.”

The Fate of Greenland

The Fate of Greenland: Lessons from Abrupt Climate ChangeGary Comer was a wealthy retired American who found on a private voyage in 2001 that he was able to easily navigate the normally ice-bound Northwest Passage in northern Canada. It perturbed him that he could do so and resulted in his substantial funding of scientific research into the global extent of abrupt climate change. Glaciologist Richard Alley, oceanographer Wallace Broecker and geologist George Denton were leading scientists in the research he funded, and are co-authors with editor Philip Conkling of a newly published book which draws on the past decade of their and others’ work. The Fate of Greenland: Lessons from Abrupt Climate Change is a handsomely produced volume, lavishly illustrated with stunning photographs, many of them taken by Comer himself.  It’s written for a general audience, albeit at times requiring close attention from readers when the complexities of some of the scientific detective work are explained.

Climate Capitalism

Climate Capitalism: Capitalism in the Age of Climate ChangeClimate protection is good business.  Entrepreneurs and companies who engage in it are prospering. That’s the message of L. Hunter Lovins and Boyd Cohen in their recently published book Climate Capitalism: Capitalism in the Age of Climate Change . They energetically urge entrepreneurs and businesses to take advantage of the opportunities opened by the need to combat climate change, or climate chaos as they often call it. Acting to protect the climate will unleash a new energy economy, and it will be profitable for business.

The authors are at pains throughout the book to relate hundreds of stories of the many companies that are already reaping the benefits of action. Their positive assurances are evidence-based. The businesses whose success they recount are not waiting on the outcome of the interminable wrangling of politicians but accepting the sustainability imperative and positioning themselves for competitive business advantage in a world that will no longer tolerate unsustainable behaviour.
