‘Embers’: Stranded Assets
Wole Talabi’s short story ‘Embers’ (2024) explores the potential consequences of energy transition for a rural community in Nigeria, focusing on one oil worker who cannot let go of dreams of petrochemical prosperity.
Kawashida fuel cells were invented by a team of scientists at the ShinChi Technology Company of Japan […] By using a proprietary genetic modification technique to rewire the metabolism of a heterotrophic bacterial strain, making it autotrophic, and then further splicing the synthetic microbe with a cocktail of high cell density, rapid reproduction genes, Dr. Haruko Kawashida and her team created a living, breathing, renewable supply of energy for the planet. The synthetic autotroph used concentrated sunlight to efficiently consume carbon dioxide and exchange electrons, creating a steady stream of electricity.1
How convenient! And as if its abundant, net carbon-negative energy weren’t enough, Kawashida cell technology also revolutionizes wastewater treatment. It’s a near-perfect deus ex machina for the climate crisis.
But not everyone is happy. When Kawashida decimates the oil industry, Uduak is abruptly cut off from his sponsored scholarship. Cast adrift, Uduak becomes a kind of inverted solarpunk protagonist—he uses grit and ingenuity not to jury-rig funky green utopiatech, but rather to attempt to revive the village’s derelict oil refinery. Even though clean energy is widely available, Uduak argues that the village’s real needs remain unmet, and he remains hostile to the post-carbon vision laid out by his idealistic rival, Affiong.
The story comes to a grisly and tragic conclusion—murder, arson, suicide. Without excusing Uduak’s rather OTT response, we can see that there is a clear lack of compassion to support him transition to the era of a stabilised climate. One wonders if Uduak might also have a point: will the village as a whole be left behind by government, industry and civil society? Just as Uduak was left behind by the village?
Uduak becomes what is sometimes called a ‘stranded asset,’ something once valuable, whose value has vanished because of a probably permanent shift in its circumstances. The story’s core tension—between his thwarted social mobility and the new sustainable technology—reflects the current dilemma of green transition for petro-states like Nigeria.
It also implies broader questions about energy transitions. Within science fiction, transformation of the energy system often forms the hard-to-imagine bridge between the dystopian present and the ambiguously utopian future. There are the dilithium crystals and warp cores in Star Trek, there is the Grid in Iain M. Banks’ Culture novels. But the questions which arise are not just about what energy will power the future. They are also about how societies will allocate and manage such energy. Could energy itself somehow be the foundation of a just and equitable economy? If the flow of energy were to directly underpin the flow of money, could this support systems that are more cooperative, collective, and liberated, and less exploitative? Systems that are not just energy-based, but also just based pure and simple?
Energy-based currencies in speculative fiction
These are certainly questions which have fascinated science fiction writers, although (spoiler alert) I’m not convinced that their answers are that plausible, at least not in their current forms. In Kim Stanley Robinson’s Mars trilogy (1992-1996), moneys are developed based on calories or on hydrogen peroxide fuel. His Ministry for the Future (2020) imagines a currency based on atmospheric carbon removed or carbon emissions avoided (not energy-based exactly, but strongly linked with energy). Michael Cisco’s Animal Money (2015) briefly plays with the idea of an active “verb money” as opposed to reified noun money2; Cisco’s title refers (sort of) to money used by animals. Of course, in the real world, cattle have been an early and enduring currency which also constitute a kind of energy currency. Many commodity currencies and social currencies have been tied to animals, plants, or products derived from them, and therefore to the energy metabolisms of the species: grain, tea, firewood, charcoal, peat, beeswax, oil, ethanol.
In a different medium, Jonathan Keats’s Electrochemical Currency Exchange Co. (2012) was a business, or an art project, which exploited “electrochemical arbitrage” between the differences in the metallic content of Chinese and American coinages to generate a faint electrical current. Keats’s entry to the 2016 Future of Money award, which challenged designers to imagine an alternative origin story for money, suggested that money originated in the sun. Keats’s entry also extended this with a ‘solar dollars’ concept, where banknotes would be woven with photovoltaic materials, turning each one into a mini solar panel:
Money originated with the sun. Long before the development of banking, and even before the evolution of the human species, photosynthetic organisms worked out systems to amass, save, and spend solar energy. For many plants, energy earned by collecting sunlight gets banked as sugars, which may be invested in personal growth or spent on sex.
Our economic systems, which emerged with agriculture, merely emulate what we’ve observed in nature. However, we don’t do it as well as the average rhododendron. We expend an enormous amount of energy working for money that has almost no energy value. […]
Humans can do much better by learning from the origin of money. We can reengineer currency not only to store energy more efficiently, but also to continuously generate new energy from sunlight.
The concept is simple: Embedded with flexible solar cells, solar dollars and pounds will become more valuable just by lying around. Thin-film photovoltaic materials will charge a paper-based supercapacitor, which will work as a rechargeable battery. Each note will also include a self-resonant coil to allow for wireless energy transfer from the supercapacitor to household appliances or the grid. Plus, the money will feature a matrix of light-emitting quantum dots to display current value, indicated in watts.3
Sometimes money may be tied to a particular type of energy, kinetic energy, or movement of mass through space. Postage stamps might be considered generalised ‘movement credits,’ and have sometimes historically functioned like money. But they are unlike most commodity moneys, since their ‘intrinsic’ use value is so clearly a creature of law, in a manner resembling fiat currency. Early in the US Civil War, the North switched to new stamps to deprive the South of its stamp stock assets. Later, in response to specie hoarding and inadequate ledger-based money infrastructure, the Post Office issued wartime ‘postage currency,’ some initially featuring perforated edges and images of stamps. Postage currency functioned similarly to ‘shinplasters,’ small dollar denomination notes issued by businesses and local authorities, which were also widely in circulation at the time. Later, email and digital cash would also have entwined histories, through shared concerns with privacy and decentralisation, and anti-spam mechanisms.
The idea that money might be not only a store of value, but a vehicle for moving value to where it is needed—has reappeared in speculative visions of future economies. In The Shape of Things to Come (1933), H.G. Wells envisions a world administered by a unified authority intent on reconstructing civilisation after cataclysmic upheavals. Central to this future is the World Transport Union (WTU), an international organisation that establishes a standardised global transport network. As part of its operations, the WTU introduces the “air dollar,” a form of currency directly tied to physical transport costs. Each air dollar pays for moving one kilogram of goods one kilometre on WTU aircraft.
Even though Star Trek’s Federation is proudly post-money, its warp drive-enabling dilithium crystals behave suspiciously like a commodity money; there is also at least one mention of rationing the teleportation system via Transporter Credits.4
In Frank Herbert’s Dune series (1965-1985), the commodity money spice is a potent mélange of time and space; from Children of Dune (1976):
Not without reason was the spice often called “the secret coinage.” Without melange, the Spacing Guild’s heighliners could not move. Melange precipitated the “navigation trance” by which a translight pathway could be “seen” before it was traveled.5
In Charles Stross’s space opera Neptune’s Brood (2014) there are three kinds of money: fast, medium, and slow. There is a sense in which fast money is highly liquid, medium money is somewhat liquid, and slow money is scarcely liquid at all. Slow, in fact, sort of means illiquid. But what is striking about thinking through these currencies is the qualitative shifts involved. Slow money is essentially implicated with a different kind of activity. An economic anthropologist might say that it constitutes its own ‘sphere of exchange’ or its own ‘transactional order.’ That is, slow money is “the currency of world-builders,” used for financing starships and colonies.
Charles Stross, Neptune’s Brood: A Space Opera (Ace: 2014)
There’s a lot of diversity here already. What does it really mean for a currency to be ‘based on energy’? Toward the end of Douglas Adams’s The Restaurant at the End of the Universe (1980), the Golgafrinchans—a gang of uncannily familiar bungling interplanetary colonists—attempt to establish a new currency.6
“How can you have money,” demanded Ford, “if none of you actually produces anything? It doesn’t grow on trees you know.”
“If you would allow me to continue …”
Ford nodded dejectedly.
“Thank you. Since we decided a few weeks ago to adopt the leaf as legal tender, we have, of course, all become immensely rich.”
The Golgafrinchans might struggle a bit with inflation, especially during the lush summer months.7 However, the Golgafrinchans have thought of everything.
“So in order to obviate this problem,” he continued, “and effectively revaluate the leaf, we are about to embark on a massive defoliation campaign, and … er, burn down all the forests. I think you’ll all agree that’s a sensible move under the circumstances.”
The twist is that the planet settled by the Golgafrinchans is prehistoric Earth. The Golgafrinchans are us. How extravagant is this satire? Is anyone on Earth really reckless enough to burn down trees in an effort to form a new currency? Surely not!
Unless. Unless, of course, those trees decay. And turn to peat. And then compress down into coal. And then, some time later, someone invents Bitcoin.
Bitcoin and other proof-of-work cryptocurrencies may be considered energy-based currencies, but in a very particular way. Bitcoin is created by spending money on electricity to power computers that guess the answers to mathematical puzzles (Bitcoin mining). But if Bitcoin is energy-based, it is in roughly the opposite sense from that intended by many science fiction writers and utopian thinkers. Unlike utopian visions where energy-based currencies promote sustainability, the energy that ‘backs’ Bitcoin is consumed and unavailable for other uses. Bitcoin is based on used-up energy, not available energy.
For a currency based on available energy, we might start with the Technocrats. The Technocracy movement of the early 20th century, emerging during the Great Depression, proposed a radical restructuring of society and the economy based on scientific principles and technological efficiency, rejecting both capitalism and democracy. In some Technocrat schemes, we encounter the impulse to base money on something incontrovertibly real. As Howard Scott wrote in 1933, “all forms of energy, of whatever sort, may be measured in units of ergs, joules, or calories […] A dollar may be worth—in buying power—so much today and more or less tomorrow, but a unit of work or heat is the same in 1900, 1929, 1933 or the year 2000.”8 For Technocrat Theodore Bruce Yerke, however, even the term currency carried unwanted connotations. Technocracy would scientifically optimise economic production, Yerke argued in Futuria Fantasia, a fanzine produced by the young Ray Bradbury. “In the TECH THERE IS NO MEDIUM OF EXCHANGE, THERE IS ONLY A METHOD OF TECHNOLOGICAL ACCOUNTING. […] Technocracy is NOT a political or revolutionary movement. It is 100% American.”9 During its heyday in the 1930s the Technocracy movement had links with pulp sci-fi, such as Nat Schachner’s series ‘The Revolt of the Scientists’ (1933), where Schachner depicted the revolutionary destruction of existing money. Technocracy is a little hard to place politically, although there are some unmistakable resonances with contemporary big tech bumbling into its fash era.
In speculative fiction, Christopher Stasheff’s A Company of Stars (1992) features the energy-based Kwaher. In Starhawk’s Fifth Sacred Thing (1994) money is “backed by energy, human and other sorts” and the “basic unit of value is the calorie.”10
‘Do you use money?’ the woman next to her asked.
‘Our credits function like money, but they’re not backed by gold or silver. They’re backed by energy, human and other sorts, and our basic unit of value is the calorie. So a product is valued by how much energy goes into its production, in terms of labor and fuel and materials that themselves require energy to produce. And part of that accounting is how much energy it takes to replace a resource that is used. Something that works with solar or wind power becomes very cheap. Anything requiring irreplaceable fossil fuels is generally too expensive to think about.’
‘But do you have rich and poor?’ the same woman asked.
‘We’re each guaranteed a share of the wealth of the past and of the resources, which translates into a basic stipend of credits. As I said before, you could live on that, frugally, if you really didn’t want to work. But if you do work, you earn work credits, and the more you work the more you earn, so there’s incentive for those who want personal advancement. And if you do something really spectacular, achieve something fabulous, people bring you gifts.’
‘Don’t people cheat?’ asked a woman at the end of the table.
‘All the accounts are public. Your whole work group sees the bill you put in each week, and believe me, they know if it’s accurate. If not, you’ll hear about it, and if necessary they’ll bring it up before your Guild or council. Of course, some jobs don’t lend themselves to counting hours, like mine, or like being an artist or a musician. We get a fixed stipend.’11
Dave Gerrold’s A Matter for Men (1981), where the currency is the kilocalorie (or KC, ‘casey’), succinctly makes the case for energy-based currencies:
[…] you can only measure your wealth by the amount of difference you make in the world. […] The physical universe uses heat to keep score. […] We want our money to be an accurate measure, so we use the same system as the physical universe: ergo, we have the KC standard, the kilocalorie.12
Of course this is a sleight of hand. The universe doesn’t need to ‘keep score,’ the universe simply exists. As for the ‘amount of difference’ that results from an energy expenditure, this depends on the context: the kWh powering a life support machine is not equal to the kWh powering a brightly luminous billboard selling Coca-Cola to nobody on a desolate rural road.
Nonetheless, we might suppose that there’s often a rough correlation between energy input and economic value, and in certain contexts—perhaps transport, and some industrial processes like smelting—quite a close correlation. There are also semi-precedents for energy currencies, such as prepaid electricity cards (at the household level), Renewable Energy Certificates (intended to spur investment in renewables), assets in energy derivatives markets (futures, options, swaps), as well as the currencies of oil-producing countries (petrocurrencies) which tend to be tied to the price of oil.
What is this correlation between energy and value were strengthened? How feasible is a full-blown energy money?
Is energy-based money possible?
Let’s look at several concepts. Our currency could be structured so that a holder could redeem it directly for a specified amount of energy. Your coin says 10 kWh, so you can get 10 kWh for it. A ‘central energy bank’ would need to maintain sufficient energy reserves to redeem these claims.
This is conceptually simple, like a gold-backed currency. Logistically though, it quickly begins to look like a castle-in-the-sky. Storing vast amounts of energy is far more challenging than storing gold bullion. One might even imagine a literal castle-in-the-sky approach: immense weights suspended at high elevations, descending to turn generators; together with water pumped uphill into tarns, ready to drive turbines; underground caverns tense with compressed air; molten salt and other thermal storage systems; the silhouettes of grid-scale batteries littering the horizons. With all this in place, perhaps enough energy could be stored to back a currency.13 But it surely wouldn’t last long. Inefficiencies in storing and releasing energy would make the system appear extremely wasteful. As the world transitions to renewables, energy storage is already a critical challenge. Intermittent sources like solar and wind depend on precisely these storage systems to balance grids and ensure reliability. One of the reasons gold has sometimes worked well as a backing is that it is mostly useless.14 Diverting energy to monetary reserves would sap resources needed to decarbonise and meet rising demands.
A second, more feasible concept does not maintain reserves centrally. Instead, the currency would be pegged to a basket of energy-related goods, priced on the open market. Traditional monetary policy, including interest rate adjustments, would manage the value of the energy currency so that a 1kWh coin could reliably purchase about an hour’s running time for a 1kW appliance. Fiscal interventions, such as taxes and subsidies applied to energy production, could also help to maintain this peg.
In theory this approach could work, but its benefits are not entirely clear. Perhaps it would strengthen trust in the currency and the broader economy, assuming the peg could be upheld. Psychologically and culturally, a currency denominated in energy might also foreground energy scarcity. Today, people will shake their heads and huff, What a waste of taxpayers’ money! In the world of this energy-referenced currency, they might instead grumble, What a waste of planet-dwellers’ energy! Such grumbles could be especially revolutionary during our current transition era, in which societies built around the expectation of relatively abundant fossil energy suddenly need to use energy much more intelligently.
But overall, I don’t think this concept would achieve what writers like Stasheff, Robinson, Starhawk, and Gerrold are really getting at with their energy currencies. One might intuit that an energy peg guarantees greater stability compared with ordinary money. As Technocrat Howard Scott wrote, “a unit of work or heat is the same in 1900, 1929, 1933 or the year 2000” (q.v.). But improved stability would actually be unlikely.15 If monetary policy is tied to keeping the currency aligned with energy, it leaves less scope for tackling inflation. Historically, the link between money and energy has fluctuated considerably, so pinning it down may well displace that volatility elsewhere.16
In fact, the real fascination with energy currencies is about more than stability. It’s about justice and truth. We want money to measure the ‘real cost’ of things, yet we know many prices ignore environmental or social harm—‘negative externalities,’ in economists’ terms. We feel that anchoring our money to energy would account for important externalities, the ones tied to energy use.17 For example, an energy money society surely wouldn’t revolve around mass individual ownership of gas-guzzling internal combustion engines, would it? Even better, we wouldn’t need interfering government apparatchiks to break the news to us, because the physical universe itself would be breaking that news. It wouldn’t be Obama or Biden coming for your guns, for your gleaming ’67 Ford Mustang, your sun-scorched stretch of Route 66, your fizzing neon diner sign and your jukebox of dreams, your haze of light and shimmer where the road meets the sky. No, you would simply roll up your sleeves, and contend with the reality before you, finally made plain by honest money. Because the true cost of oil to the climate would now be factored into the price of gas at the pump, wouldn’t it?
Wouldn’t it? Well, no actually! There is a conceptual confusion here. Pegging a currency to the cost of energy has no inherent effect on the externalities of energy production or consumption. In Starhawk’s solarpunk future, “a product is valued by how much energy goes into its production” (q.v.). But the energy peg doesn’t get us even to that, let alone to a sustainability-constrained version of it. Even if all goods and services were priced in kWhs, their actual prices would still be determined in the usual way, by the product’s demand and supply, and a few other factors.18
An example will help to clarify this. Imagine, say, a hand-woven scarf for sale at a local craft fair. Its energy inputs might be minimal. But because each scarf is lovingly and skilfully crafted by a single artisan, supply is low. These scarves are in high demand for their beauty and glamour, so customers will pay many kWh coins for them, far in excess of the kWh embodied in their production. The reverse is also true: even with an energy peg, energy can still be too cheap in terms of environmental sustainability.
This means there’s nothing preventing gas at the gas station pouring into gas-guzzling SUVs far too cheaply, except now it’s too cheap in kWh coin. There’s nothing stopping intensive energy crop farming from ravaging local habitats, raising food prices, and polluting waterways. Serried rows of empty skyscrapers can still loom, beautifully lit up and temperature-controlled all night long. Even the crypto rigs can keep churning. The whole fiery, ecocidal kit-and-kaboodle can continue apace, only now gloriously denominated in kWh, with a cool dollar sign logo drawn in fire.
Our instinct tells us that transactions denominated in energy units will automatically reflect underlying physical energy flows. This instinct is wrong. This brings us to the third concept. What would it take for goods and services to reflect an estimate of the energy wrapped up in them, as Starhawk describes? It doesn’t have to be perfect—if a particular pashmina happened to take more energy to make than all the other similar pashminas, we don’t need to know that—but can we have good enough estimates for general categories of goods?
The key thing here is not so much energy-based money, as energy-based prices. So most obviously, the answer is price controls, as in a centrally planned economy where officials attempt to fix prices based on kWh invested in production. In fact, we can think of two different versions here: one where prices always reflect embodied energy but are denominated in dollars, yen, euros etc., and another version where prices reflect embodied energy and are denominated in kWh or some other energy unit.
Modelling how much energy is embodied in broad categories of goods and services is challenging but not impossible—there is a very partial precedent in Emissions Factor databases, used in carbon accounting. In Kim Stanley Robinson’s Red Mars, the character Vlad gestures toward the complexity of the calculations, especially when putting energy values on services. Vlad is talking about calories rather than kWh, as we have been, but the principle is the same.
“If you burn our bodies in a microbomb calorimeter you’ll find we contain about six or seven kilocalories per gram of weight, and of course we take in a lot of calories to sustain that through our lives our output is harder to measure, because it’s not a matter of predators feeding on us, as in the classic efficiency equations — it’s more a matter of how many calories we create by our efforts, or send on to future generations, something like that. And most of that is very indirect, naturally, and it involves a lot of speculation and subjective judgement. If you don’t go ahead and assign values to a number of non-physical things, then electricians and plumbers and reactor builders and other infrastructural workers would always rate as the most productive members of society, while artists and the like would be seen as contributing nothing at all.”
“Sounds about right to me,” John joked […]19
Beyond energy, goods and services also embed other scarce or valuable inputs—labour time, natural resources, etc. Should pricing reflect only total energy input, or should there be some weighting to also reflect the ratio of energy to other inputs? And if those other inputs are themselves valued according to their embodied energy, what recursive dynamics emerge? Different methodologies would incentivise different behaviors. Crucially, energy-based pricing involves empirical data and mathematical modelling, but it also involves political and ethical value judgments.
Kim Stanley Robinson, Red Mars (Del Rey: 2021)
Let’s imagine an economy where prices reflect embodied energy. We have come a long way since the early Soviet Union’s Gosplan fumbled through its material balances exercises. In our techno-utopian system of embodied energy prices, some form of automated Life Cycle Analysis forms the backbone, while each price carries associated metadata about how confident the system is in its accuracy. Each product or service’s cost is updated based on current data about energy use throughout its supply chain. These prices dynamically account for factors such as changing energy sources, production methods, and transport distances. There is a slight premium associated with uncertainty, so there is an incentive to fill in gaps in the data. There are of course weightings to support the transition to renewable energy. Machine Learning and other statistical techniques track and forecast shifts across the whole system.20
Set aside questions of data surveillance, or how people might hack, speculate on, or game the system. Would it fulfil the basic promise of Starhawk’s energy money (albeit in a very different way)? I’m not sure that it would. These science fiction authors want monetary systems that are rooted more directly in human vitality and in the earth’s ecological resources. They want money that helps to allocate resources well, responsive to both human wants and needs and to the energy implication of those wants and needs. They want something spontaneous, bottom-up, springing from the universe itself, not imposed top-down bureaucratically. The use of AI and sophisticated data analytics might spark a flicker of interest—Perhaps AI is the lens with which we can read the true state of the universe? But ultimately AI is just another layer of human decision-making, akin to opaque bureaucracy.
A fourth concept would be to give up on energy as that ‘special something,’ that ‘unobtanium,’ that can fix money once and for all. Instead, we might tie money creation directly to renewable energy generation. After all, money is a human device, not a property of the universe. Since modern money comes into being through lending, it could instead be lent into existence with strings attached—namely, that it must be used for funding clean energy projects. This dispenses with the idea of a currency that measures value in the same way the universe does, or captures an unfiltered physical reality. Instead, it treats money as something we consciously design and adapts it to accelerate and stabilise the growth of renewable energy. Money creation is very much in demand within the utopian imagination these days. Such a proposal would need to prove itself not only against the status quo, but also against many other proposals for reforming money creation, such as using it to fund Universal Basic Income.
While we have mostly been occupied with ambitious or fanciful ideas for monetary reform, I suspect that these science fictional imaginaries also strongly inform important ongoing debates in energy economics. Earlier, I briefly mentioned Renewable Energy Certificates (RECs), which allow renewable energy producers to register and receive a tradable certificate for each megawatt-hour of electricity they expect to generate. These certificates are tracked in a database and can be bought by suppliers or other companies wishing to label their energy as ‘green.’ When a supplier buys a certificate and provides that equivalent amount of electricity to customers, the certificate is retired from the system. However, unless you have your own on-site renewables, buying green electricity doesn’t change what physically comes out of your sockets; the grid still delivers a collective mix. Rather, by purchasing RECs, your utility company obtains the right—according to established accounting practices—to count your energy usage as renewable.
If it sounds like an awful greenwashing scam, it’s not quite that bad. The purpose is to spur investment in renewable energy. It is almost like a deliberate double-counting: a renewable energy producer can sell their energy to the grid, but they can also sell their RECs based on that production. This means that renewable energy projects that might not have been financially viable suddenly become viable: they have an extra income stream.
However, frustration has been mounting with the unbundled RECs system, with some evidence suggesting that it hasn’t really led to much additional investment in renewable energy. There are parallels with carbon offsetting too: big, rich companies have been able to purchase RECs fairly cheaply. and make technically legitimate claims that they are 100% renewable energy powered, and perhaps delaying much-needed operational changes. Meanwhile, the things they physically do need to be powered somehow, and some of that power comes from coal, oil, and gas.
Longer-term Power Purchase Agreements (PPAs) have been seen as one good antidote to the RECs approach. Another paradigm that is gaining traction is 24/7 hourly matching, also known as 24/7 carbon free energy. This approach requires energy buyers to match their consumption with renewable energy generation in the same region every single hour, rather than simply offsetting total use over a longer period. By making sure electricity is generated locally and at the same time it is consumed, 24/7 hourly matching should prevent companies from claiming green energy sourced from distant places (where all the energy happens to be green anyway, so the additional investment is minimal or nonexistent), or mismatched time slots. It should encourage companies to actually change what they do: for example, scheduling more energy intensive activities for when the sun is shining and the wind is blowing, and the grid has renewable energy to spare. It may also encourage investment in more robust renewable infrastructure, often supported by energy storage to handle off-peak or fluctuating demand. By tying consumption to real-time local supply, 24/7 hourly matching aims to reduce reliance on fossil fuels, bolster genuine renewable availability, and encourage a more resilient, sustainably powered grid. At the time of writing, in early 2025, there is some beef simmering in the tech world, with Google championing 24/7 hourly matching, and trying to get it written into the influential Greenhouse Gas Protocol, while Amazon wants to double down on an even more liberalised version of RECs.
The criticisms of Amazon’s position are convincing. But what if 24/7 hourly matching involves a kind of unobtanium? In fact, I am suspicious of 24/7 hourly matching, for reasons rooted (partly) in science fiction. I know some brilliant and passionate individuals who are working on it, and in many ways I trust them more than I trust my own paranoid instincts. So perhaps it will be a step in the right direction. But 24/7 hourly matching does feel like yet another expression of that same desire which animates these science fiction stories: to align our economies with an objective, scientifically given reality, and sweep aside subjective value judgments. As we’ve seen, things tend to be a little more complicated, and there is a risk that by burying these value judgments, we place them out of reach of popular scrutiny and dissent. We may also place them beyond more radical possibilities for the democratisation of energy. Energy currencies may have their uses, but they need to be as responsive to the realities of human values, as to the metrics of energy flows.
