Part 3 – Standing slightly past the edge of the cliff
The Tooth Fairy Syndrome that I discussed in Part 2 is, in my view, the fundamental reason why those holding onto BAU will grab every piece of information that can possibly, superficially, back up their ideology and twist it to suit their viewa, generating much confusion in the process. It is also probably fair to say that the advocates of various versions of “energy transition” are not immune to this kind of syndrome when they remain oblivious to the issues explored in Parts 1 and 2. Is it possible to go beyond such confusion?
The need to move away from ideology
The impact of the Tooth Fairy Syndrome is all the more felt in the main media and among politicians – with the end result that so many lay people (and many experts) end up highly confused about what to think and do about energy matters. Notably, we often encounter articles advocating, even sensationalising, various energy transition technologies or instead seeking to rubbish them by highlighting what they present as problematic issues without any depth of analysis. For example, a 2013 article from the Daily Mail was highlighted in recent discussions among energy experts as a case in point. The UK is indeed installing large numbers of subsidized, costly diesel generators to be used as back-up at times of low electricity supplies from wind turbines. This article presented this policy as very problematic but failed to set things in perspective about what such issues say about the challenges of any energy transition.
In New Zealand, where I lived close to half of my life before a return to my dear Provence (De reditu suo mode, as a wink to an earlier post by Ugo) about 73% of electricity is deemed renewable (with hydro 60%, geothermal 10%, wind 3%, PVs about 0.1%); the balance being generated from gas and coal. There is a policy to achieve 90% renewables by 2025. Now, with that mix we have had for many years something like what the UK is building, with a number of distributed generators for emergency back-up without this being a major issue. The main differences I see with the UK are that (1) in NZ we have only about 5M people living in an area about half that of France (i.e. the chief issue is a matter of renewable production per head of population) and (2) the system is mostly hydro, hence embodying a large amount of energy storage, that Kiwi “sparkies” have learned to manage very well. It ensues that a few diesel or gas generators are not a big deal there. By contrast, the UK in my view faces a very big challenge to go “green”.
The above example illustrates the need to extricate ourselves from ideology and look carefully into systems specifics when considering such matters as the potential of various technologies, like wind turbine, PVs, EVs, and so on, as well as capacity factors and EROI levels in the context of going 100% renewable. All too often, vital issues keep being sidestepped by both BAU and non-BAU parties; while ignoring them often leads to erroneous “solutions” and even dangerous ones. So as a conclusion of this three-part series focused on “enquiring into the appropriateness of the question”, here are some of the fundamental issues that I see in front of us (the list is not exhaustive):
At least since the early 1970s and the Meadows’ work, we have known that the globalised industrial world (GIW) is on a self-destructive path, aka BAU (Business as usual). We now know that we are living through the tail end of this process, the end of the Oil Age, precipitating what I have called the Oil Fizzle Dragon-King, Seneca style, that is, after a slow, relatively smooth climb (aka “economic growth”) we are at the beginning of an abrupt fall down a thermodynamic cliff.
The chief issue is whole system change. This means thinking in whole systems terms where the thermodynamics of complex systems operating far from equilibrium is the key. In terms of epistemology and methods, this requires what in anthropology is called the “hermeneutic circle”: moving repeatedly from the particulars, the details, to the whole system, improving our understanding of the whole and from this going back to the particulars, improving our understanding of them, going back to considering the whole, and so on. Whole system replacement, i.e. going 100% renewable, requires a huge energy embodiment, a kind of “primitive accumulation” (as a wink to Marx) that presently, under the prevailing paradigm and technology set, is not feasible. Having the “Energy Hand” in mind, where does this required energy may come from in a context of sharp decline of net energy from oil and Red Queen effect, and concerning renewable, inverse Red Queen/cannibalisation effects? As another example of the importance of whole system thinking, Axel Kleidon has raised the question of the viability of very large-scale wind versus direct solar. Solely considering the performances and cost of this or that alternative energy technology won’t suffice. Short of addressing the complexities of whole system replacement, the situation we are in is some kind of “Apocalypse now”. The chief challenge I see is thus how to shift safely, with minimal loss of life (substantial loss of life there will be; this has become unavoidable), from fossil-BAU (and thus accessorily nuclear) to 100% sustainable, which means essentially, in one form or another, a direct solar-based society.
We currently have some 17 TW of power installed globally (mostly fossil with some nuclear), i.e. about 2.3kW/head, but with some 4 billion people who at best are grossly energy stressed, many who have no access to electricity at all and only limited transport, in a context of an efficiency of global energy systems in the order of 12%. To address the Oil Fizzle Dragon-King and the Perfect Storm that it is in the process of whipping up, I consider that we need to move to 4kW/head for the whole population (assuming it levels off at some 8 billion people instead of the currently expected 11 billions), plus some 10TW additional to address climate change and other ecological energy related issues, hence about 50TW, 100% direct solar based, for the whole spectrum of energy uses including transport; preferably over 20 years. Standing where we now are, slightly past the edge of the thermodynamic cliff, this is my understanding of what’s required.
In other words, going “green” and surviving it (i.e. avoiding the inverse Red Queen effect) means increasing our Energy Hand from 17 TW to 50 TW (as a rough order of magnitude), with efficiencies shifting from 12% to over 80%.
To elaborate this further, I stress it again, currently the 17 TW do not even suffice to cater for the whole 7.3G global population and by a wide margin. Going “green” with the current “renewable” technology mix and related paradigm would mean devoting a substantial amount of those 17 TW to the “primitive accumulation” of the “green” system. It should be clear that under this predicament something would have to give, i.e. some of us would get even more energy stressed, and die, or as the Chinese and Indians have been doing for a while we would use much more of remaining fossil resources but then this would accelerate global warming and many other nasties. Alternatively we may face up to changing paradigm so as to rapidly steer away from global EROIs below 10:1 and global energy efficiency around 12%. This is the usual “can’t have one’s cake and eat it” situation writ large.
Put in an other way, when looking at whole societal system replacement one must look at the whole of what’s required to make the system work, including people and their own energy requirements – this is fundamentally a matter of system boundary definitions related to problem definition (in David Bhom’s sense). We can illustrate this by considering the Kingdom of Saudi Arabia (KSA). As a thought experiment, remove oil (the media have reported that KSA’s Crown Prince has seen the writing on some wall re the near end of the oil bonanza). This brings the KSA population from some 27M down to some 2M, i.e. some 25M people are currently required to keep oil flowing at some 10M bbl/day (including numerous Filipino domestics, medics, lawyers, and so on) plus about three times that population overseas to supply what the 25M require to keep the oil flowing…
Globally, I estimate very roughly that some 1.5G people, directly related to oil production, processing distribution and transport matters did require oil at above $100/bbl for their livelihood (including the Filipino domestics). I call them the Oil People. Most of them currently are unhappy and struggle; their “demand” for goods and services has dropped considerably since 2014.
So all in all, whole system replacement (on a “do or die” mode) requires considering whole production chain networks from mining the ores, through making the metals, cement, etc., to making the machines, to using them to produce the stuff we require to go 100% sustainable, as well as the energy requirements of not only the Oil People but the full compendium of the Energy People involved, both the “fossil” ones and the “green” ones; while meanwhile we need to keep existing fossil-based energy systems going as much as possible. Very roughly the Energy People are probably in the order of 3 billion people (and it is not easy to convert a substantial proportion of the “fossil” ones to “green”, including their own related energy requirements – this too has a significant energy cost). This is where Figure 6, with the interplay of Red Queen and the inverse Red Queen, comes in.
In my view at this whole system level we do have a major problem. Given the very short time window constraint, we can’t afford to get it wrong in terms of how to possibly getting out of there – we have hardly enough time to have one go at it.
Remaining time frame
Indeed, under the sway of the Tooth Fairy (see Part 2) and an increasingly asthmatic Red Queen, we no longer have 35 years, (say up to around 2050). We have at best 10 years, not to debate and agonise but to actually do, with the next three years being key. The thermodynamics on this, summarised in Part 1, is rock hard. This timeframe, combined with the Oil Pearl Harbor challenge and the inverse Red Queen constraints, means in my view that none of the current “doings” renewable-wise can cut it. In fact much of these stand to make matters worse – I refer here to current interactions between efforts at going green largely within the prevailing paradigm and die hard BAU efforts at keeping fossils going, as perhaps exemplified in the current UK policies discussed earlier.
Notwithstanding its apparent power, the GIW is in fact extremely fragile. It embodies a number of very weak links in its networks. I have highlighted the oil issue, an issue that defines the overall time frame for dealing with “Apocalypse now”. In addition to that and to climate change, there are a few other challenges that have been variously put forward by a range of researchers in recent years, such as fresh water availability, massive soil degradation, trace pollutants, degradation of life in oceans (about 99% of life is aquatic), staple food threats (e.g. black stem rust, wheat blast, ground level ozone, etc.), loss of biodiversity and 6th mass extinction, all the way to Joseph Tainter’s work concerning the links between energy flows, power (in TW), complexity and overshoot to collapse.
These weak links are currently in the process of breaking or are about to break, the breaks forming a self-reinforcing avalanche (SOC) or Perfect Storm. All have the same key timeframe of about 10 years as an order of magnitude for acting. All require a fair “whack” of energy as a prerequisite to handling them (the “whack” being a flexible and elastic unit of something substantial that usually one does not have).
It’s all burnt up
Figure 7 – Carbon all burnt
Recent research shows that sensitivity to climate forcing has been substantially underestimated, meaning that we must expect much more warming in the longer term than touted so far. This further exacerbates what we already knew, namely that there is no such thing as a “carbon budget” of fossils the GIW could still burn, and no way of staying below the highly political and misleading 2oC COP21 objective (Figure 7).
The 350ppm CO2 equivalent advocated by Hansen et al. is a safe estimate – a boundary crossed in the late 1980s, some 28 years ago. So the reality is that we can’t escape actually extracting CO2 from the atmosphere, somehow, if we want to avoid trying to survive in a few mosquito infested areas of the far north and south, while some 80% of the planet becomes non-habitable in the longer run. Direct Air Capture of atmospheric CO2 (DAC) is something that also requires a fair “whack" of energy, hence the additional 10TW I consider is required to get out of trouble.
Figure 8 – EROI cognitive failure
The “Brexit” saga is perhaps the latest large-scale demonstration of cognitive failure in a very long series. That is to say, the failure on the part of decision-making elites to make use of available knowledge, experience, and expertise to tackle effectively challenges within the timeframe required to do so.
Cognitive failure is probably most blatant, but largely remaining unseen, concerning energy, the Oil Fizzle DK and matters of energy returns on energy investments (EROI or EROEI). What we can observe is a triple failure of BAU, but also of most current “green” alternatives (Figure 8): (1) the BAU development trajectory since the 1950s failed; (2) there has been a failure to take heed of over 40 years of warnings; and (3) there has been a failure to develop viable alternatives.
However, although I am critical of aspects of recent evaluations of the feasibility of going 100% renewable, I do think it remains feasible with existing knowledge, no “blue sky” required, i.e. to reach in the order of 50TW 100% solar I outlined earlier, but I also think that a crash on the cliff side of the Seneca is no longer avoidable. In other words I consider that it remains possible to partly retrieve the situation while the GIW crashes so long as enough people do realise that one can’t change paradigm on the down side as one may do on the upside of a Seneca, which presently our elites, in full blown cognitive failure mode, don’t understand.
To illustrate this matter further and highlight why I consider that production EROIs well above 30:1 are necessary to get us out of trouble consider Figure 9.
Figure 9 – The necessity of very high EROIs
This is expanded from similar attempts by Jessica Lambert et al., to perhaps highlights what sliding down the thermodynamic cliff entails. Charles Hall has shown that a production EROI of 10:1 corresponds roughly to an end-user EROI of 3.3:1 and is the bare minimum for an industrial society to function. In sociological terms, for 10:1 think of North Korea. As shown on Figure 8, currently I know of no alternative, either unconventional fossils based, nuclear or “green” technologies with production EROIs (i.e. equivalent to the well head EROI for oil) above 20:1; most remain below 10:1. I do think it feasible to go back above 30:1, in 100% sustainable fashion, but not along prevalent modes of technology development, social organisation, and decision-making.
The hard questions
So prevailing cognitive failure brings us back to Bohm’s “enquiry into the appropriateness of the question”. In conclusion of a 2011 paper, Joseph Tainter raised four questions that, in my view, squarely address such an enquiry (Figure 10). To date those four questions remain unanswered by both tenants of BAU and advocates of going 100% renewable.
We are in an unprecedented situation. As stressed by Tainter, no previous civilisation has ever managed to survive the kind of predicament we are in. However, the people living in those civilisations were mostly rural and had a safety net, in that their energy source was 100% solar, photosynthesis for food, fibre and timber – they always could keep going even though it may have been under harsh conditions. We no longer have such a safety net; our entire food systems are almost completely dependent on that net energy from oil that is in the process of dropping to the floor and our food supply systems cannot cope without it.
Figure 10 Four questions
Figure 10 summarises how, in my view, Tainter’s four questions, his analyses and mine combine to define the unique situation we are in. If we are to avoid sliding all the way down the thermodynamic cliff, we must shift to a new “energy pool”. In this respect, dealing with the SOC-like Perfect Storm while carrying out such a shift both excludes “shrinking” our energy base (as many “greens” would have it) and necessitates abandoning the present highly wasteful energy use paradigm – hence the shift from 17TW fossil to 50TW 100% solar-based and with over 80% useful uses of energy that I advocated earlier, over a 20 to 30 years timeframe.
Figure 11 – Ready to jump into a new energy pool?
Figure 11 highlights that humankind has been through a number of such shifts over the last 6 million years or so. Each shift has entailed:
(1) a nexus of revolutionary innovations encompassing thermodynamics and related techniques,
(2) social innovation (à la Cornelius Castoriadis’ imaginary institution of society) and
(3) innovations concerning the human psyche, i.e. how we think, decide and act.
Our predicament, as we have just begun to slide down the fossil fuels thermodynamic cliff, similarly requires such a nexus if we are to succeed at a new “energy pool shift”. Just focusing on thermodynamics and technology won’t suffice. The kind of paradigm change I keep referring to integrates technology, social innovations and innovation concerning the human psyche about ways of avoiding cognitive failure. This is a lot to ask, however it is necessary to address Tainter’s questions.
This challenge is a measure of the huge selection pressure humankind managed to place itself under. Presently, I see a lot going on very creatively in all these three intimately related domains. Maybe we will succeed in making the jump over the cliff?
