Socialism and Electricity: Renewables and Decentralisation Versus Nuclear

Introduction

Matthew Huber and Fred Stafford’s insistence that “electricity is poised to be a central site of political struggle in the twenty-first century” (Citation2023, 65) is welcome and timely. But the approach they set out in “Socialist Politics and the Electricity Grid,” in Catalyst journal, is flawed. They argue that the basis for a socialist energy supply system is centralised electricity generation, primarily from nuclear power; that renewable electricity generation should play only a minor role; and that decentralised renewables are unworthy of support, for both technological and political reasons. Indeed, Huber adds, in an article on the Unherd website (Citation2023), neoliberalism fostered decentralised renewables while undermining centralised generation, and socialists seduced by “green” renewables have unwittingly become neoliberalism’s allies.

In this response, I suggest, first, that nuclear power has overcome none of the problems that led several generations of socialists to oppose it (links with the military, absence of waste disposal, and so on), and that it features only in the most impoverished views of the transition away from fossil fuels and the most conservative, state-centred versions of socialism. Second, I discuss the decades-long trend towards decentralisation of electricity networks – a reality for which Huber and Stafford fail to account. I argue that our focus should shift away from outworn pro-nuclear arguments towards a discussion of whether, and how, socialism can challenge capital’s control of electricity technologies, including decentralised renewables, and turn them to our advantage. Third, I challenge Huber and Stafford’s claims that renewables are, by comparison to nuclear, inherently inimical to labour organisation and to public forms of ownership. Finally, I question the misrepresentations on which Huber relies in an account of the relationship through the history of energy technologies and neoliberalism. I build on arguments presented previously (Pirani Citation2023a, Citation2023b, Citation2023c).

Nuclear and Renewables

In their Catalyst article, Huber and Stafford (Citation2023, 75) write: “From a socialist perspective aiming for reliable nonstop, zero-carbon power, nuclear energy would be the foundation of the grid.” The risks associated with nuclear are exaggerated in popular attitudes; problems with radioactive waste have been “overstated.” They do not engage with researchers of nuclear who assert that there is: (1) no long-term solution to the waste problem; (2) that there is “no working deep repository for high level waste anywhere”, despite limited progress in Finland and Sweden (Cullen Citation2021); (3) that a solution is “decades away”; and (4) that plans for new nuclear in the UK should be frozen “until we have a geological disposal facility”, which is timetabled for the 2040s but likely to take longer (Laville Citation2022).

Huber and Stafford pass over in silence the way that nuclear power implies and requires a strong state, and its close connection with the military – an omission all the more remarkable, given the occupation since 2022 of Europe’s largest nuclear plant, at Zaporizhzhia, by the Russian army, which bears responsibility for the collapse of the nearby Kakhovka hydro plant (Glantz et al. Citation2023). For the rich tradition of socialist writing on technology, the nuclear-military connection is not only about such “accidents,” but about deeper-going economic and technological relationships. Only nuclear reactors produce the fissile material needed for nuclear bombs; military imperatives shape national industrial supply chains more broadly; the overlaps in education, design, research and security are all extensively researched. Civilian nuclear power has been in long-term decline due to its high cost, but has proved “surprisingly resilient” to market conditions in a limited group of countries, due to this interdependence (Stirling and Johnstone Citation2018).

Ultimately, the way socialists see nuclear power is bound up with our views of potential post-capitalist futures. Huber and Stafford’s vision (Citation2023, 79) is “of ‘big public power’, in which the public sector would subsidise the mass buildout of large-scale zero-carbon energy generation infrastructure including nuclear power and, where geography suits, renewables.” Against this, I commend the view held by Cullen (Citation2021) that nuclear power is “antithetical to the world we want to see. From its origin as a figleaf to distract us from the grim truth of mutually assured destruction, to its recent resurrection as a bogus solution to climate change, it is inherently bound up with violent state forms and paranoid and secretive hierarchies.”

Views of nuclear also vary according to our approaches to the transition away from fossil fuels. The two most vital changes needed are: (1) to transform the way final energy is used (e.g. by insulating homes to reduce the need for heating, improving public transport to reduce the need for cars, and ending wasteful forms of consumption), and (2) to reduce the throughput of energy in technological systems (e.g. by replacing gas boilers with heat pumps). The remaining energy required must be produced with non-fossil-fuel technologies, of which renewables and nuclear are the most developed. The copious scenario analysis literature shows that climate change can only be dealt with in the course of deep-going social transformations (Allwood et al. Citation2019, Grubler et al. Citation2018, van Vuuren et al. Citation2018). For socialists, these transformations are bound up with overcoming and superceding capitalism (Pirani Citation2018, Pirani, Citation2023a).

For the present discussion, there are three relevant points that I would like to emphasise. First, climate change deprives us of time. Nuclear power stations take many years to build, while decentralised renewable energy systems do not. Second, the future of electricity networks must be considered in the context of broader economic changes overshadowed by climate change, and the need for transforming final energy use and reducing throughput, mentioned above (in his writing on “degrowth,” discussed elsewhere, Huber (Citation2022, 31–32 and 162–175) has remained agnostic on energy consumption and throughput scenarios). Third, highly flexible electricity networks are both necessary for reducing throughput and transforming final energy use – and, happily, also facilitate decentralised renewables. Integrating nuclear power stations that generate large, unchanging quantities of electricity into such networks may be less easy.

Under the present political conditions, in which labour movements and social movements are struggling for change under capitalism, choices made by the state about which energy resources to invest in do matter. Huber and Stafford (Citation2023, 78) advocate opting for nuclear, despite the extraordinary expense: it “needs socialism to grow – or at least a form of public investment that socialises the costs of construction and does not privatise the gains.” The corollary should be spelled out: resources invested in nuclear would not be invested in renewables.

Discussions among socialists would benefit from greater attention to the transition scenarios mentioned above, which afford a way into some of the social and technological issues. It would also be worthwhile to develop a socialist critique of “100 percent renewables” scenarios (i.e. models depicting hypothetical paths towards electricity networks run solely from renewable electricity, without any fossil fuels or nuclear) developed by researchers from engineering and scientific backgrounds (Pirani Citation2023d). Huber and Stafford, characteristically, dismiss these scenarios as “largely based on the models of one researcher, Mark Z. Jacobson.” They are mistaken. A recent survey covered the work of some thirteen research teams (Brown et al. Citation2018, Heard et al. Citation2017).

Renewables and Network Integration

Huber and Stafford (Citation2023, 65–66) propose “core principles” on which to base a socialist approach to electricity. They argue that electricity should be produced as a public good, rather than a commodity, that control by capital will always subvert this goal, and that for this reason “public or alternative ownership structures” are crucial. All this is welcome. Further, they propose that electricity is a “complex material system of production,” conducive to socialist planning, which “consequently requires a deep materialist understanding of how it works and how it might be transformed.” In my view, the conclusions they draw from this – that this understanding points toward “the importance of centralised, large-scale reliable power generation like hydroelectric dams and nuclear power, as opposed to decentralised, small-scale and intermittent forms of power like rooftop solar panels” – need to be challenged.

Huber and Stafford refer repeatedly to the supposed threat to electricity systems from decentralised renewables: intermittency “creates unavoidable problems for grid planning”; when there is too much wind and solar, that leads to curtailment, and when there is too little, electricity prices go up. They highlight the dangers of blackouts to “the very survival of the system,” but, unfortunately, remain silent on the fact that the world’s most devastating electricity blackouts (Puerto Rico 2017, Bangladesh 2022, Pakistan 2023) occurred in fossil-fuel-dominated networks for reasons that had nothing to do with renewables. They claim, mistakenly, that it is “still not clear how [renewables] can provide reliable power for the entire grid the way centralised power plants do today.”

These assertions are disproved by reality. While renewables’ share of global primary energy supply remains pitifully small, renewables generate a substantial share of electricity in a significant number of rich countries. Wind and solar account for 41, 40 and 35 percent respectively of electricity generated in Germany, the UK and Spain, three of the largest European economies, and 43 percent in California, which consumes more electricity than most nations. Denmark generates 61 percent of its electricity from wind and solar and 23 percent from modern biofuel use. Variable renewables’ share of electricity generation in Scotland averaged 60 percent in 2019-2021. This expansion of renewables, that, like fossil fuels and nuclear, are predominantly controlled by corporations and the state, is fraught with dangers, not least to the people of countries being plundered for minerals used in equipment manufacture. Grid integration, though, is less a danger, and more of an engineering challenge (Pirani Citation2023b).

Wherever variable renewables expand, network upgrades are required. In particular, grids supplied by a large proportion of renewable generation need more, and newer, ways to store energy and to ensure grid stability. Because electricity grids are controlled by capital, just as the power stations are, the infrastructure investment needed to modernise them lags far behind the shift towards renewables in power generation. The most common problems caused by this failure to modernise are shortages of transmission and storage capacity (see e.g. IRENA Citation2023b, 11–14). The chronic level of curtailment of wind power in China in the late 2010s is noteworthy; so is the success of electricity transmission and distribution companies in fixing it (Chen et al. Citation2022). In the U.S.A. and Europe, the years-long queues for electricity generators to get a grid connection have become public scandals (Rand et al. Citation2022) But the underlying cause of poor infrastructure is not renewable technologies, but underinvestment. And the cause of that is, often, neoliberalism.

As for Huber and Stafford’s point that wholesale electricity prices may rise when less power than expected comes from wind – well, that’s how (pending improved weather forecasting) markets regulate supply and demand (the example they cite, of too little wind in Europe in December 2022, is factually incorrect. See Pirani Citation2023b, section 2.4). The problem is not the wind, it is the way markets function.

Not only does Huber and Stafford’s “deep materialist understanding” fail to explain what is going on in Scotland, California, and elsewhere; it also omits any account of the trends over several decades towards decentralisation of electricity networks, and, more recently, from uni-directional to multi-directional operation. The networks installed in rich countries in the first half of the twentieth century, and across much of the global south in the second half, were designed to carry electricity in one direction: mostly from big coal, gas and nuclear power stations, to users. Peak centralisation was in the 1970s. Combined heat and power plants, and power stations using combined-cycle gas turbines (CCGT) built in the 1980s and 90s were smaller; wind and solar plants, even utility-scale ones, smaller still (IRENA Citation2023a, 17–18, 64–66; Patterson Citation1999, 68–70, 72–75, 114–116).

As the number and type of electricity sources increase, networks adapt to manage their inputs, in the context of the “third industrial revolution,” which started with semiconductors and gave rise to a new generation of technology, including personal computers, mobile phones and the internet. The next big change, now getting underway, is towards flows of electricity in multiple directions, with the potential for microgrids, including those using direct current only, and for supply by decentralised generators to local users. These changes raise vital political issues, including: (1) whether these decentralised technologies, which are largely but not completely developing under corporate and state control, have the potential to enhance and be strengthened by, forms of social ownership and control, to work towards the decommodification of electricity; and (2) whether co-ops, community energy projects and municipal ownership forms may be stepping stones in these directions (Pirani Citation2023b).

Huber and Stafford’s concern that the addition of renewables disrupts an existing system might have made sense ten or more years ago. But the technology – if not the economics – of electricity networks has moved on. Rather than engage with this reality, it is unfortunate that they fall back on the following polemical misrepresentations:

□ They quote Mark Nelson, a consultant and nuclear advocate, to the effect that “claiming cheap renewables are a viable solution for our grid system is like claiming flimsy tents are a viable solution for the housing crisis.” They incorrectly describe Nelson as an “energy analyst,” imputing to his words an authority they do not have.

□ Huber and Stafford claim that “cheap prices of renewable energy don’t include the transmission lines to their remote locales or the costly back-up required when the weather isn’t favourable,” and that “the limited use value of solar and wind” leads to “broader system costs” not covered by renewable generators. They ignore the complexities of the integration into grids of variable renewables, and the substantial body of research on the costs (e.g. Elliott Citation2020, 7–9; Heptonstall and Gross Citation2021; IEA/NEA Citation2020). They misrepresent modelling by Robert Idel to create an exaggerate impression of renewables costs (For details, see Pirani, Citation2023a, “Note: infrastructure costs.”). The simplified framing of renewables as an economic burden to an existing system has long been a staple of fossil-fuel-based generators’ propaganda, answered by mainstream energy economists with proposals for market reform and by socialists with calls for public ownership and decommodification. It has no place in a serious discussion.

□ Huber and Stafford pay unwarranted attention to the microscopic portion of off-grid solar in the global North, writing: “While the Elon Musks of the world hawk the benefits of ‘delinking’ from the grid through the individual purchases of rooftop solar equipment and battery storage, we must fight for the expansion of electricity as universal public infrastructure.” Yes, Elon Musk is a dangerous clown, and, yes, a small number of rich households may see rooftop solar as the road to a reactionary, isolationist, off-grid existence. But in the big picture, they are irrelevant. The overwhelming majority of rooftop solar, whether household, municipal or corporate, is connected to the grid. All these solar panels are part of a universal infrastructure. The barriers to that infrastructure being geared to use, and not profit, is not that the panels are decentralised, but that neither panels nor networks are publicly or commonly owned and controlled.

It would be regrettable if discussion among socialists were to be dominated by outdated pro-nuclear arguments, rather than by the real-world problems in electricity networks and other energy systems posed by climate change and the crises of capital. Collectively we should develop a critique of the work by engineers in politically mainstream contexts who assume markets as a key regulating mechanism (e.g. Cochran et al. Citation2014, Hanna et al. Citation2018, Kroposki et al. Citation2017), and build on arguments for greater public control (Elliott Citation2017, Elliott Citation2020, Kristov Citation2019). Research by a group of European scholars on the potential for flexible grids and decentralised renewables to open the way to forms of common ownership and to decommodification of electricity deserves our attention (Giotitsas et al. Citation2020, Citation2022). They envisage “commons-based peer production,” under which “smart” technology is used not to trade electricity as a commodity but to share it as a common good; they show how software technologies that currently “align with the existing liberalised market with ancillary and balancing services” also “open up the possibility for democratising electricity if governed as a commons.”

Renewables, Labour and Socialism

Matthew Huber proposes that (i) renewable electricity generation is, by its nature, hostile to working-class organisation in a way that nuclear and hydro are not; (ii) decentralised technologies are poorly suited to public ownership, and that using them to enhance forms of social ownership at sub-national level is a blind alley; (iii) in any case such “localism” is at odds with Marxism; and (iv) there is a split in “the Left” between traditional labour unions that go with centralised generation, and “environmentalists and ecosocialists” who like decentralised renewables. I suggest that each link in this logical chain is broken.

Let us take up some of these arguments, which are important to the direction of the climate justice and labour movements.

Renewables and Neoliberalism

So powerful is his crusading fervour against decentralised renewables, that Huber (Citation2023) does the following: (i) paints decentralisation as a product of neoliberalism; (ii) claims inherent links between renewables and private capital, and between nuclear and public ownership; and (iii) sees environmentalists and leftists who embrace renewable electricity dragged along behind an “anti-social [neoliberal] reaction against society itself.” None of this withstands scrutiny.

Conclusions

Renewable electricity generation is not perfect – the social and environmental impacts of its materials supply chains are only the most obvious of its drawbacks. But it operates without fossil fuels or carbon emissions. Unlike nuclear power, it is (i) free of inherent links with fearsome state structures and the military, and (ii) highly compatible with more flexible networks, reductions in throughput and rapid changes in energy end-use that are the most important ways of reducing greenhouse gas emissions. The increasing decentralisation of electricity generation is not perfect either. It is a technological change that has been in progress for decades, in the context of the “third industrial revolution.” Huber and Stafford ignore this process, and suggest, mistakenly, that technological decentralisation equals political decentralisation, and that both are somehow inimical to working-class organisation and socialism. They ignore, too, the rich history of socialist writing on technology and its relationship to society, to construe a false alliance between nuclear power and working-class interests. To support this, Huber offers a sketched history of renewable electricity generation, rewritten to depict it as a child of neoliberalism, that is replete with distortions.

A starting-point for discussion on the role of electricity systems in the transition away from fossil fuels, and in struggles against capitalism, in my view, is an assessment of the technological changes underway, and the corrosive effect of the corporate and state interests under whose control it is taking place. Perspectives and policies must be considered together with the need for transformation of energy end-use, for reduction of throughput and for the supply of electricity to the hundreds of millions of people who do not have it. In rich countries, the potential of co-operative, municipal and other forms of public ownership must continue to be tested, alongside traditional demands for public ownership. Finally, the interests of workers directly employed by electricity companies must be considered not sectionally but as part of the broader working-class and societal interest.
