On My Enthusiasm For Solar Energy

I am a solar energy enthusiast. The energetic parts of the universe are clustered around stars. We sit here on this dusty ball of rock and water, heated continually by the Sun. The difference between when we face toward our local star and when we face away from it is — in the most literal sense — day and night. Our lives on Earth are already solar-powered; the plants (and plant-eating animals) we eat get their energy from photosynthesis. The trees and other biomass we have used for energy for much of our history, as well as the fossil fuel reserves we use today are forms of stored solar energy from earlier organisms that died and were trapped under the Earth. Wind energy and tidal energy are perturbations of dynamical systems heated by solar energy. Even the nuclear energy we use extracted from fissionable uranium and plutonium is stored from supernovae in early stars that exploded and pushed the complex elements — including the carbon, nitrogen and oxygen in our bodies — out across the universe.

It is not so much a question of whether we use solar energy, but whether we use direct solar energy, or some derivative form. As our civilisation has advanced and grown, we have had to tap into larger sources to meet the demand for cheap and easily-accessible energy. Our technological sophistication and understanding of basic physics and chemistry has had to grow with our energy hunger to take advantage of different forms of energy; windmills, steam engines, oil refineries, cold water reactors and photovoltaic panels, and so on. In the long run, it is a mathematical certainty that to sustain our civilisation at present levels, or to grow and increase energy consumption we must transition to renewable energy both because quantities of fossil fuels and star fuels like uranium and plutonium on Earth are finite.

The availability of direct solar energy on Earth dwarfs other energy sources, including renewable energy:

All that is necessary in the long run for renewable energy sustainability is that the level of output exceeds the level of input enough to provide a reliable energy source. Even at current solar efficiencies — and thus assuming that the technology won’t improve — photovoltaic solar generates seven times more energy than it takes to generate:

While this is not currently as good as oil or natural gas or coal, it already beats shale oil and biofuels. The beautiful thing about solar energy is that there is so much of it that the technology does not have to be greatly efficient. And prices are falling and efficiencies are improving. While some renewables like wind and hydroelectric are more efficient, they are not abundant enough to even cover the bulk of our energy needs today. In the short run, combined with hydroelectric and wind and nuclear there is a real basis for long-term renewable energy sustainability. To smooth the transition, renewable technology needs investment and development.

In the long run, while obviously renewables still cost a lot more than non-renewables in the marketplace, but we have already established that that cannot last forever. Even the supply of uranium is limited. While we may discover superior technologies like cold fusion, we should be completely prepared for the eventuality that we don’t discover a better technology. While photovoltaic solar remains the largest and most long-term source of available energy — and thus the best hope for the continuation and expansion of sustainable human civilisation — it should receive a bulk of funding and development, and we should assume that in the very long run it should meet the bulk of our energy needs. There are still challenges like solar energy storage, but these challenges are being surmounted with improved battery technologies, and improved distribution technologies such as microgrids. 

Of course, if the photovoltaic solar price trend known as the Swanson Effect that has seen solar fall over 99% in cost since the 1970s continues, then solar will reach and exceed parity with other energy sources and be crowned the winner by the market based simply on  low cost. After all, solar energy is superabundant compared to the alternatives, so it would not be at all surprising for it to become the cheapest. But even if the Swanson Effect does not play out and solar does not become super-cheap, direct photovoltaic solar is extremely likely to play a major role in continued human civilisation on this planet and elsewhere.

When Solar Becomes Cheaper Than Fossil Fuels

Solar power has been getting cheaper and cheaper:

20130110_stc001

Current estimates suggest that solar might be as cheap as coal by the end of the decade, and half the cost of coal by the end of the next decade:

If the trend continues for another 8-10 years, which seems increasingly likely, solar will be as cheap as coal with the added benefit of zero carbon emissions. If the cost continues to fall over the next 20 years, solar costs will be half that of coal. These predictions may in fact be too conservative given that First Solar have reported internal production costs of 75 cents (46 pence) per watt with an expectation of 50 cents (31 pence) per watt by 2016.

When applied to electricity prices this predicts that solar generated electricity in the US will descend to a level of 12 cents (7 pence) per kilowatt hour by 2020, possibly even 2015 for the sunniest parts of America.

What does that mean? Cheap, decentralised, plentiful, sustainable energy production. This would be a massive relief to global markets that have been squeezed in recent years by the rising cost of oil extraction, which has been passed onto consumers. Falling energy prices — all else being equal — mean more disposable income to save and invest, or to spend.

Some will say that solar is inherently unviable due to the difficulty of storing energy. But huge advances have been made on that front in recent years, and improvements continue.

This — if it comes to pass — would be a basis for a period of strong growth. Independence from foreign oil. Independence from falling EROEI yields on conventional energy. A robust decentralised grid. A new sustainable energy supercycle — and new growth in other industries that benefit from falling energy costs. This has the potential to reverse so many of the negative trends we have seen emerge in recent years, and prove wrong the Malthusians who claim that humanity has over-extended itself and that the era of growth is over.

In the long term, this makes me pretty bullish. But unfortunately this is all still years away. Maybe five, maybe ten, maybe twenty years. We’re not out of the woods yet. Not for a long time.

Free Market Ecology

These gargantuan global conferences where the emissaries of governments meet in hallowed halls to thrash out a global planning agenda — dressed in the clothes of ecology, or sustainable development, or whatever the buzzword of the day — are a waste of time.

They are a waste of time for the taxpayer, who has to stump up to pay for such efforts. They are a waste of time for the protestors who swarm to such events holding placards and shouting slogans. They are a waste of time for the ecologists who — whether right or wrong — believe that the present shape of human civilisation is unsustainable. Possibly the only group that really benefits are the self-perpetuating bureaucratic classes, who often take home huge salaries they could never earn in the private sector.

And the Malthusian targets of the bureaucracy have a history of missing.

The Guardian notes:

Rio+20 was intended as a follow up on the 1992 Earth Summit, which put in place landmark conventions on climate change and biodiversity, as well as commitments on poverty eradication and social justice. Since then, however, global emissions have risen by 48%, 300m hectares of forest have been cleared and the population has increased by 1.6bn people. Despite a reduction in poverty, one in six people are malnourished.

If these bureaucratic classes knew the first thing about economics or markets, they would begin to question whether such conferences — and all the promises, intergovernmental commissions, and regulatory pledges they spawn — are necessary. The more I question, the more I come to believe that all that is needed to halt any man-made ecological crises are free markets and free speech.

The history of human civilisation has been one of triumph over the limits of nature. While we have had our ups and downs, recent projections of imminent ecological ruin — such as those in the 1970s produced by Ehrlich and Holdren and the Club of Rome, or earlier by Keynes, Malthus and Galton (etc) — have all failed to materialise. But the trend goes back much further, into the distant past. Throughout our history our species has done what has been necessary to survive. Humanity has lived on this planet for upwards of 500,000 years, and through that time, we have survived a myriad of climate changes — solar variation, atmospheric variation, cycles of glaciation, supervolcanoes, gamma ray bursts, and a host of other phenomena.

It will be no different this time. We are dependent on our environment for our life and for our future. That is widespread knowledge, and so as the capable and creative species that we are, we have already developed a wide array of technological solutions to potential future environmental problems. This is a natural impulse; humanity as individuals and as a species hungers for survival, for opportunities to pass on our genes.

As I wrote last month:

If we are emitting excessive quantities of CO2 we don’t have to resort to authoritarian centralist solutions. It’s far easier to develop and market technologies (that already exist today) like carbon scrubbing trees that can literally strip CO2 out of the air than it is to try and develop and enforce top-down controlling rules and regulations on individual carbon output. Or (even more simply), plant lots of trees and other such foliage (e.g. algae).

If the dangers of non-biodegradable plastic threaten our oceans, then develop and market processes (that already exist today) to clean up these plastics.

Worried about resource depletion? Asteroid mining can give us access to thousands of tonnes of metals, water, and even hydrocarbons (methane, etc). For more bountiful energy, synthetic oil technology exists today. And of course, more capturable solar energy hits the Earth in sunlight in a single day than we use in a year.

The only reason why these technologies are not widespread is that at present the older technologies are more economically viable. Is that market failure? Are markets failing to reflect our real needs and wants?

No; those who so quickly cry “market failure!” fail to grasp markets. Certainly, I think GDP is a bad measure of economic growth. But throwing out the concept of money altogether as a measure of society’s needs and wants is completely foolish. Markets are merely an aggregation of society’s preferences. Capital and labour is allocated as the market — in other words, as society — sees fit. As Hayek showed in the 1930s, the market gives society the ability to decide how a good or service should be distributed based on individuals willingness to give money for it. The market gives feedback to producers and consumers through the price mechanism about the allocation of resources and capital, which in turn allows on the basis of individual consensual decisions corrections that prevent shortages and surpluses. Under a planned system there is no such mechanism.

The fact that greener technologies have not yet been widely adopted by the market is merely a symptom of the fact that society itself is not yet ready to make a widespread transition. But the fact that research and development and investment continues to pour into green technologies shows that the market is developing toward such an end.

Solar consumption has gone parabolic:

And so it will continue; as society evolves and progresses, the free market — so long as there is a free market — will naturally reallocate resources and labour based on society’s preferences. Without a free market — and since 2008 when the banks were bailed out and markets became junkiefied intervention-loving zombies, it is highly dubious that there is such a thing as a free market in the West — planners will just end up guessing at how to allocate resources, labour and capital, and producing monstrous misallocations of capital.

The political nature of such reallocation is irrelevant; whether the centralists call themselves communists or socialists or environmentalists, their modus operandi is always the same: ignore society’s true economic preferences, and reallocate resources based on their own ideological imperatives (often for their own enrichment).

My view is that the greatest threat to the planet’s ecology is from the centralists who wish to remove or pervert the market mechanism in order to achieve ideological goals. It is not just true that removing the market mechanism retard society’s ability to evolve into new forms of production, resource-allocation, and capital-allocation based on society’s true preferences. The command economies of the 20th Century — particularly Maoist China and Soviet Russia — produced much greater pollution than the free markets. Under a free market, polluters who damage citizens or their property can be held to account in the market place, and through the court system.There is no such mechanism through the kind of command of economy that the centralists seem to wish to implement.

The answer is not central planning and government control. The answer is the free market. 

Keynesianism & Eugenics

The theory of output as a whole, which is what The General Theory of Employment, Interest and Money purports to provide, is much more easily adapted to the conditions of a totalitarian state.

John Maynard Keynes

In looking at and assessing the economic paradigm of John Maynard Keynes — a man himself fixated on aggregates — we must look at the aggregate of his thought, and the aggregate of his ideology.

Keynes was not just an economist. Between 1937 and 1944 he served as the head of the Eugenics Society and once called eugenics “the most important, significant and, I would add, genuine branch of sociology which exists.” And Keynes, we should add, understood that economics was a branch of sociology. So let’s be clear: Keynes thought eugenics was more important, more significant, and more genuine than economics.

Eugenics — or the control of reproduction — is a very old idea.

In The Republic, Plato advocated that the state should covertly control human reproduction:

You have in your house hunting-dogs and a number of pedigree cocks. Do not some prove better than the rest? Do you then breed from all indiscriminately, or are you careful to breed from the best? And, again, do you breed from the youngest or the oldest, or, so far as may be, from those in their prime? And if they are not thus bred, you expect, do you not, that your birds and hounds will greatly degenerate?  And what of horses and other animals? Is it otherwise with them? How imperative, then, is our need of the highest skill in our rulers, if the principle holds also for mankind? The best men must cohabit with the best women in as many cases as possible and the worst with the worst in the fewest,  and that the offspring of the one must be reared and that of the other not, if the flock is to be as perfect as possible. And the way in which all this is brought to pass must be unknown to any but the rulers, if, again, the herd of guardians is to be as free as possible from dissension.  Certain ingenious lots, then, I suppose, must be devised so that the inferior man at each conjugation may blame chance and not the rulers and on the young men, surely, who excel in war and other pursuits we must bestow honors and prizes, and, in particular, the opportunity of more frequent intercourse with the women, which will at the same time be a plausible pretext for having them beget as many of the children as possible. And the children thus born will be taken over by the officials appointed for this.

Additionally, Plato advocated “disposing” with the offspring of the inferior:

The offspring of the inferior, and any of those of the other sort who are born defective, they will properly dispose of in secret, so that no one will know what has become of them. That is the condition of preserving the purity of the guardians’ breed.

In modernity, the idea appears to have reappeared in the work first of Thomas Malthus, and later that of Francis Galton.

Malthus noted:

It does not, however, seem impossible that by an attention to breed, a certain degree of improvement, similar to that among animals, might take place among men. Whether intellect could be communicated may be a matter of doubt: but size, strength, beauty, complexion, and perhaps even longevity are in a degree transmissible. As the human race could not be improved in this way, without condemning all the bad specimens to celibacy, it is not probable, that an attention to breed should ever become general.

Galton extended Malthus’ thoughts:

What nature does blindly, slowly and ruthlessly, man may do providently, quickly, and kindly. As it lies within his power, so it becomes his duty to work in that direction.

Margaret Sanger — the founder of Planned Parenthood — went even further, claiming that the state should prevent the “undeniably feeble-minded” from reproducing,  and advocated “exterminating the Negro population”.

And these ideas — very simply, that the state should determine who should live, and who should die, and who should be allowed to reproduce — came to a head in the devastating eugenics policies of Hitler’s Reich, which removed around eleven million people — mostly Jews, gypsies, dissidents, homosexuals, and anyone who did not fit with the notion of an Aryan future — from the face of the Earth.

Of course, the biggest problem with eugenics is that human planning cannot really control nature. Mutation and randomness throw salt over the idea. No agency — even today in the era of genetics — has the ability to effectively determine who should and should not breed, and what kind of children they will have.

As Hayek noted:

The recognition of the insuperable limits to his knowledge ought indeed to teach the student of society a lesson of humility which should guard him against becoming an accomplice in men’s fatal striving to control society – a striving which makes him not only a tyrant over his fellows, but which may well make him the destroyer of a civilization which no brain has designed but which has grown from the free efforts of millions of individuals.

Keynes’ interest in this topic appears to have descended from his contempt for the individual, and individual liberty. He once wrote:

Nor is it true that self-interest generally is enlightened; more often individuals acting separately to promote their own ends are too ignorant or too weak to attain even these.

The common denominator in all of these examples — and in my view, the thing that brought Keynes toward eugenics — is the belief that the common individual is too stupid to be the captain of his own destiny. Instead, the state — supposedly equipped with the best minds and the best data — should centrally plan. Eugenicists believe that the state should centrally plan human reproduction, while Keynesians believe that the state should centrally engineer recovery from economic malaise through elevated spending. Although it would be unwise to accuse modern Keynesians of having sympathy for eugenics, the factor linking both of these camps together is John Maynard Keynes himself.

Keynes’ description of an economic depression — that a depression is a fall in the total economic output — is technically correct. And many modern Keynesian economists have made worthwhile contributions — Hyman Minsky, Steve Keen, Michael Hudson, and Joe Stiglitz are four examples . Even the polemicist Paul Krugman’s descriptive work on trade patterns and economic agglomeration is interesting and accurate.

The trouble seems to begin with prescriptions. Keynesianism dictates that the answer to an economic depression is an increase in state spending. And on the surface of it, an increase in state spending will lift the numbers. But will momentarily lifting the numbers genuinely help the economy? Not necessarily; the state could spend millions of dollars on subsidies for things that nobody wants, wasting time, effort, labour and taxes and thus destroying wealth. And the state can push a market into euphoria — just as Alan Greenspan did to the housing market — creating the next bubble and the next bust, requiring an even bigger bailout. State spending creates additional dependency on the state, and perverts the empirical market mechanism — the genuine underlying state of demand in a market economy — which signals to producers what to produce and not produce. Worst of all, centralist policies almost always have knock-on side-effects that no planner could foresee (causality is complicated).

So Hayek’s view on the insuperable limits to knowledge applies as much to the economic planner as it does to the central planner of human reproduction.

While eugenicists and Keynesians make correct descriptive observations — like the fact that certain qualities and traits are inheritable, or more simply that children are like their parents — their attempts to use the state as a mechanism to control these natural systems often turns out to be drastically worse than the natural systems that they seek to replace.

As Keynes seems to admit when — in the German language edition of his General Theory — he noted that the conditions of a totalitarian state may be more amenable to his economic theory, the desire for control may be the real story here.

Keynesianism brings more of the economy under the control of the state. It is a slow and creeping descent into dependency on the state. As we are seeing in Europe today, cuts in state spending in a state-dependent economy can cause deep economic contraction, providing the Keynesian more confirmation for his idea that the state should tax more, and spend more.

That is, until nature intervenes. Just as a state-controlled eugenics program might well spawn an inbred elite suffering hereditary illnesses as a result of a lack of genetic diversity (as seems to have happened with the inbred elite Darwin-Galton-Wedgwood clan), so a state-controlled economy may well grind itself into the dirt as it runs out of innovation as a result of a lack of economic diversity. Such a situation is unsustainable — no planner is smarter than nature.

Mining the Skies

In August last year I wrote:

Concerned about resource scarcity? There’s plenty more up there. Last year, scientists confirmed that there was water on the moon. And there are metals and hydrocarbons abundant in asteroids. Metallic asteroids  possess copper, silver, gold, and all other such elements as well, though not in abundances anywhere near as large as those of their primary constituents.

It’s an age old trope, going back to John S. Lewis’ book on the subject, and one of my greater interests.

I know that Earth is finite. I know that in some limited sense Malthus — my great intellectual nemesis, albeit one who has been proven wrong and wrong again and again — could be proven right. Earth’s resources are limited simply by the fact that Earth is a limited space. If we don’t leave Earth behind, and we continue to expand we will hit Earth’s limits, if not by the end of the century (unlikely, in my view) then by the end of the millennium.

But my key message on this subject is this: Malthus will only ever be proven right if we screw up. It’s a big expansive universe, and we are smart, flexible, ingenious creatures. We don’t know how big, but the amount of resources out there seem far, far beyond the scope of the human imagination. Malthus will always be there with us, a shackle around our necks, forewarning us not to be too gluttonous, or to expand too far too fast, and to maintain an awareness of our access to resources, particularly water and sustenance. Forewarning us, I might add, of the dangers of our own arrogance. But resource pressures are something we can always conquer without resorting to any kind of nasty authoritarianism.

For just as I expected — and not a moment too soon — a cohort of the wealthy are putting their economic weight behind the idea of going out and getting more resources.

From the Telegraph:

Power players including Eric Schmidt, the Google chairman, and James Cameron, the film director, are planning to mine the final frontier: space.

They are among the backers of a new venture that will reach for the riches lying elsewhere in the solar system. Planetary Resources will be a “space exploration company to expand Earth’s resource base” according to scant information released ahead of the start-up’s launch in Seattle on Tuesday.

“The company will overlay two critical sectors – space exploration and natural resources – to add trillions of dollars to the global GDP,” was the bold claim. “This innovative start-up will create a new industry and a new definition of ‘natural resources’.”

Mr Schmidt and the internet giant’s co-founder Larry Page are listed alongside Mr Cameron, the director of Titanic and Avatar, among the venture’s investors and advisers.

The company was founded by Eric Anderson and Peter Diamandis. “Since my childhood I’ve wanted to do one thing, be an asteroid miner,” Mr Diamandis told Forbes earlier this year. “So stay tuned on that one.”

While the costs of space travel are high, the hope is that riches contained in asteroids would make the sums worthwhile. Studies suggest that gold and other metals in the earth’s crust originated from asteroids that collided with the planet during its early life.

This is not the end of the road, but the start.

In any new industry there will be failures, some dramatic. Solar energy is a wonderful principle, but Solyndra was a terrible company.

But it is a pleasing start. Human civilisation just took a step in the right direction. And the ghost of Malthus just took another crashing blow.

Two Kinds of Black Swans

The black swan is probably the most widely misunderstood philosophical term of this century. I tend to find it being thrown around to refer to anything surprising and negative. But that’s not how Taleb defined it.

Taleb defined it very simply as any high impact surprise event. Of course, the definition of surprise is relative to the observer. To the lunatics at the NYT who push bilge about continuing American primacy, a meteoric decline in America’s standing (probably emerging from some of the fragilities I have identified in the global economic fabric) would be a black swan. It would also be a black swan to the sorry swathes of individuals who believe what they hear in the mainstream media, and from the lips of politicians (both Romney and Obama have recently paid lip service to the idea that America is far from decline). Such an event would not really be a black swan to me; I believe America and her allies will at best be a solid second in the global pecking order — behind the ASEAN group — by 2025, simply because ASEAN make a giant swathe of what we consume (and not vice verse), and producers have a historical tendency to assert authority over consumers.

But black swans are not just events. They can also be non-events. To Harold Camping and his messianic followers who confidently predicted the apocalypse on the 21st of May 2011 (and every other true-believing false prophet) the non-event was a black swan. Surprising (to them at least) and high impact, because it surely changed the entire trajectory of their lives. (Camping still lives on Earth, rather than in Heaven as he supposedly expected).

To true-believing environmentalists who warn of Malthusian catastrophe (i.e. crises triggered by overpopulation or resource depletion), history is studded with these black swan non-events.

From the Economist:

Forecasters of scarcity and doom are not only invariably wrong, they think that being wrong proves them right.

In 1798 Thomas Robert Malthus inaugurated a grand tradition of environmentalism with his best-selling pamphlet on population. Malthus argued with impeccable logic but distinctly peccable premises that since population tended to increase geometrically (1,2,4,8 ) and food supply to increase arithmetically (1,2,3,4 ), the starvation of Great Britain was inevitable and imminent. Almost everybody thought he was right. He was wrong.

In 1865 an influential book by Stanley Jevons argued with equally good logic and equally flawed premises that Britain would run out of coal in a few short years’ time. In 1914, the United States Bureau of Mines predicted that American oil reserves would last ten years. In 1939 and again in 1951, the Department of the Interior said American oil would last 13 years. Wrong, wrong, wrong and wrong.

Predictions of ecological doom, including recent ones, have such a terrible track record that people should take them with pinches of salt instead of lapping them up with relish. For reasons of their own, pressure groups, journalists and fame-seekers will no doubt continue to peddle ecological catastrophes at an undiminishing speed. These people, oddly, appear to think that having been invariably wrong in the past makes them more likely to be right in the future. The rest of us might do better to recall, when warned of the next doomsday, what ever became of the last one.

Critics will note that Malthusians only have to be right once to provoke dire consequences; deaths, famines, plagues. Of course, that is the same logic that has led governments to spend trillions, and trample the constitutional rights of millions of people in fighting amateurish jihadis, when in reality more Americans — yes including the deaths from 9/11 — are crushed to death by furniture than are killed by Islamic terrorism.

But it is true, the scope of the threat posed by Malthusian catastrophe is probably an order of magnitude greater than by jihadis with beards in caves. And of course, groups like the Club of Rome and individuals like Paul Ehrlich will keep spewing out projections of imminent catastrophe.

So what were the real threats to humanity following Malthus’ predictions? Was it overpopulation? Nope. Imperial warfare killed far, far more than any famine or resource crisis in the 20th Century. To the overwhelming majority of the population, World War I — both in its origins (the assassination of an obscure archduke), its scope, its death toll, and its final ramifications (i.e. the Treaty of Versailles, the rise of Nazism and World War II) was the great black swan event, the great killer, the great menace.

Black swan events defined the 20th Century; the black swan non-events of Malthus did not. The true story of the early 20th Century was the decline of a heavily indebted, consumptive and overstretched imperial power (Britain), and the dangers to peace and international commerce as its productive and expansionistic rivals (especially Germany, but also America) rose and challenged her (in vastly different ways).

There are some real environmental concerns like the dangers posed by nuclear meltdowns, runaway global warming (although I believe a little global warming is probably a good thing, as it will keep us out of any prospective future ice age), tectonic activity, or an exotic solar event like an X-flare, but we have no clue what will hit us, when it will hit, and its branching tree of consequences. We don’t have a full view of the risks. In spite of what unsophisticated mathematician pseudo-scientists in the tradition of Galton and Quetelet may tell us, we cannot even model reality to the extent of being able to accurately foretell tomorrow’s weather.

But once again a heavily consumptive, indebted and overstretched imperial power (America) is coming to terms with the problem of decreasing power in the face of productive and expansionistic rivals (particularly China). That parallel tends to lead me to believe that imperialist warfare will be the greatest menace of the 21st Century, too. But that’s the problem with predicting the future: we simply don’t know what black swan events and non-events nature will deliver (although it would be wise not to place too much trust in politicians or the establishment media, who simply blow their own trumpet and hope for the best).

So what are we to do?

Well, I think it’s important that businesses, governments and individuals think about Malthusian concerns. Malthus’ incorrect theorising touched upon the most significant of human concerns. Quite simply, without food, water and energy we weak and fragile humans are imperilled. It’s important that governments (particularly of importer nations) devise strategies to cope with (for example) breakdowns in the international trade system. Individuals, families, businesses and communities should be aware of where their food, energy and water come from, and of alternatives in case the line of supply is cut. Keeping backups (e.g. solar panels, batteries, wind turbines, storable food and water) is a sensible precaution for all citizens. There will be shocks in the future, just as there have been in the past. We should be prepared for shocks, whatever they may be.

And we should learn to love such volatility. Nature will always deliver it. We evolved and developed with it. It is only in modernity that we have adopted systems procedures and methodologies to subdue volatility. And — as we are slowly learning via the disastrous consequences of every single failed experiment in central planning — volatility suppressed is like a coiled spring.
