The Garden of Forking Paths: Renewables are an Opportunity we Cannot Afford to Miss

  

"El jardín de senderos que se bifurcan" (J.L. Borges)

Recently, Simon Michaux argued that the transition to renewable energy is not possible for the lack of sufficient mineral resources. This conclusion was criticized by Nafeez Ahmed in a recent post. As usual in our polarized world, that led to a heated discussion based on opposing views. My opinion is that both Michaud and Ahmed are right but they see the question from different points of view. If you allow me, Ahmed is more right because he shows that the future is not running on a fixed path. Rather, it is a garden of forking paths. If we choose the right path, the transition is possible and will lead us to a better world. 

Do you remember the story of the boy who cried wolf? It tells you that you shouldn't cry wolf too many times but also that the wolf will eventually come. It illustrates how our destiny as human beings is to always choose extreme viewpoints: either we are too afraid of the wolf, or we believe it doesn't exist. Indeed, Erwin Schlesinger said, "human beings have only two modes of operation: complacency and panic." 

This dichotomy is especially visible in the current debate on the "Energy Transition" that recently flared in an exchange between Simon Michaux and Nafeez Ahmed, the first maintaining that the transition is impossible, the second arriving at the opposite conclusion. In my modest opinion, Michaud's work is correct within the limits of the assumptions he made. But these assumptions are not necessarily right. 

Models may be perfectly correct, but still unable to predict the future. 

If you really believe that they can, you are bound to make enormous mistakes -- as we saw in the way the recent pandemic was (mis)managed. 

Models are there to understand the future, not to predict it. 

The future is a garden of forking paths. Where you go depends on the path you choose. But you still need to follow one of the available paths.

Now, let me try to examine Michaux's work and Ahmed's rebuttal in light of these considerations. I went through Michaux's report, and I can tell you that it is well done, accurate, full of data, and created by competent professionals. That doesn't mean it cannot be wrong, just like the peak oil date was proposed by competent professionals but turned out to be wrong. The problem is evident from the beginning: it is right there, in the title. 

Assessment of the Extra Capacity Required of Alternative Energy Electrical Power Systems to Completely Replace Fossil Fuels 

You see? Michaux assumes from the start that we need "extra capacity" from "alternative" energy in order to "completely replace" fossil fuels. If the problem is stated in these terms, the answer to the question of the feasibility of the transition can only be negative. 

Alas, we didn't need a report of 985 pages to understand that. It was obvious from the beginning. The limits of mineral resources were already shown in 1972 by the authors of "The Limits to Growth," the report sponsored by the Club of Rome. We know that we have limits; the problem is which paths we can choose within these limits. 

This question is often touched on in Michaux's report when he mentions the need to "think outside the box" and to change the structure of the system. But, eventually, the result is still stated in negative terms. It is clear from the summary, where Michaux says, "The existing renewable energy sectors and the EV technology systems are merely steppingstones to something else, rather than the final solution." This suggests that we should stick to fossil fuels while waiting for some miracle leading us to the "final" solution, whatever that means. This statement can be used to argue that renewables are useless. Then, it becomes a memetic weapon to keep us stuck to fossil fuels; an attitude which can only lead us to disaster. 

Nafeez Ahmed perfectly understood the problems in his rebuttal. Ahmed notes several critical points in Michaud's report; the principal ones are underestimating the current EROI of renewables and the recent developments of batteries. That leads him to the statement that renewables are not really "renewable" but, at most, "replaceable." Which is simply wrong. The EROI of renewables is now large enough to allow the use of renewable energy to recycle renewable plants. Renewables are exactly that: renewable. 

You could argue that my (and Ahmed's) evaluation of the EROI of renewables is over-optimistic. Maybe, but that's not the main point. Ahmed's criticism is focused on the roots of the problem: we need to take into account how the system can (and always does) adapt to scarcity. It follows different paths among the many available. Ahmed writes: 

...we remain trapped within the prevailing ideological paradigm associated with modern industrial civilisation. This paradigm is a form of reductive-materialism that defines human nature, the natural world, and the relationship between them through the lens of homo economicus – a reduction of human nature to base imperatives oriented around endless consumption and production of materially-defined pursuits; pursuits which are premised on an understanding of nature as little more than a repository of material resources suitable only for human domination and material self-maximisation; in which both human and nature are projected as separate and competing, themselves comprised of separate and competing units.

Yet this ideology is bound up with a system that is hurtling toward self-destruction. As an empirical test of accuracy, it has utterly failed: it is not true because it clearly does not reflect the reality of human nature and the natural world.

It’s understandable, then, that in reacting to this ideology, many environmentalists have zeroed in on certain features of the current system – its predatory growth trajectory – and sought out alternatives that would seem to be diametrically opposed to those regressive features.

One result of this is a proliferation of narratives claiming that the clean energy transformation is little more than an extension of the same industrialised, endless growth ideological paradigm that led us to this global crisis in the first place. Instead of solving that crisis, they claim, it will only worsen it.

Within this worldview, replacing the existing fossil fuel energy infrastructure with a new one based on renewable energy technologies is a fantasy, and therefore the world is heading for an unavoidable contraction that will result in the demise of modern civilisation.  ... Far from being a sober, scientific perspective, this view is itself an ideological reaction that represents a ‘fight or flight’ response to the current crisis convergence. In fact, the proponents of this view are often as dogmatically committed to their views as those they criticise. ....

Recognising the flaws in Michaux’s approach does not vindicate the idea that the current structures and value-systems of the global economy should simply stay the same. On the contrary, accelerating the energy and transport disruptions entails fundamental changes not only within these sectors, but in the way they are organised and managed in relation to wider society.

My critique of Michaux doesn’t justify complacency about metals and minerals requirements for the clean energy transformation. Resource bottlenecks can happen for a range of reasons as geopolitical crises like Russia's war in Ukraine make obvious. But there are no good reasons to believe that potential materials bottlenecks entail the total infeasibility of the transition.

... we face the unprecedented opportunity and ecological necessity to move into a new system. This system includes the possibilities of abundant clean energy and transport with diminishing material throughput, requiring new circular economy approaches rooted in respect for life and the earth; and where the key technologies are so networked and decentralised that they work best with participatory models of distribution and sharing. This entails the emergence of a new economy with value measured in innovative ways, because traditional GDP metrics focusing on ever-increasing material throughput will become functionally useless.

If you can, please, try to examine these statements by Ahmed with an open mind because he perfectly frames the problem. And never forget one thing: the future is not a single path toward catastrophe. It is a garden of forking paths. We are bound to follow one of these paths: we don't know which one yet, but not all of them lead to the Seneca Cliff. In the transition to a renewable energy system, we can adapt, reduce demand, improve efficiency, deploy new technologies, and simply be happy with a more limited supply of energy at some moments. It is only the rigidity of our mental models that make us think that there are no alternatives to fossil fuels.
