Nos últimos dois séculos, milhões de pessoas dedicadas - revolucionários, ativistas, políticos, e teóricos - não conseguiram conter a trajetória desastrosa e cada vez mais globalizada da polarização econômica e da degradação ecológica. Isso talvez se deva ao fato de estarmos totalmente presos em maneiras errôneas de pensar sobre tecnologia e economia - como mostra o discurso atual sobre a mudança climática.

O aumento das emissões de gases de efeito estufa não está gerando apenas mudanças climáticas. Eles estão causando cada vez mais ansiedade climática. Os cenários do Juízo Final estão capturando as manchetes em um ritmo acelerado. Cientistas de todo o mundo nos dizem que as emissões em dez anos devem ser a metade do que eram há dez anos, ou enfrentamos o apocalipse. Crianças em idade escolar como Greta Thunberg e movimentos ativistas como a Extinction Rebellion estão exigindo que entremos em pânico. E com razão. Mas o que devemos fazer para evitar o desastre?

A maioria dos cientistas, políticos, e os líderes empresariais tendem a colocar sua esperança no progresso tecnológico. Independentemente da ideologia, existe uma expectativa generalizada de que as novas tecnologias irão substituir os combustíveis fósseis, aproveitando a energia renovável, como solar e eólica. Muitos também acreditam que haverá tecnologias para remover o dióxido de carbono da atmosfera e para "geoengenharia" o clima da Terra. O denominador comum nessas visões é a fé de que podemos salvar a civilização moderna se mudarmos para novas tecnologias. Mas "tecnologia" não é uma varinha mágica. Requer muito dinheiro, o que significa reclamações sobre mão de obra e recursos de outras áreas. Tendemos a esquecer esse fato crucial.

Eu argumentaria que a maneira como consideramos o dinheiro convencional "para todos os fins" como garantido é a principal razão pela qual não entendemos como as tecnologias avançadas dependem da apropriação de trabalho e recursos de outros lugares. Ao tornar possível a troca de quase tudo - tempo humano, aparelhos, ecossistemas, seja o que for - para qualquer outra coisa no mercado, as pessoas procuram constantemente as melhores ofertas, o que, em última análise, significa promover os salários mais baixos e os recursos mais baratos no Sul global.

É a lógica do dinheiro que criou a sociedade global totalmente insustentável e ávida por crescimento que existe hoje. Para fazer com que nossa economia globalizada respeite os limites naturais, devemos estabelecer limites para o que pode ser trocado. Infelizmente, parece cada vez mais provável que tenhamos de vivenciar algo mais próximo do desastre - como uma falha de colheita semi-global - antes de estarmos preparados para questionar seriamente como o dinheiro e os mercados são projetados atualmente.

Crescimento verde?

Pegue o problema que estamos enfrentando:seja nosso moderno, global, e a economia em crescimento pode ser alimentada por energia renovável. Entre a maioria dos campeões da sustentabilidade, como os defensores de um New Deal Verde, há uma convicção inabalável de que o problema das mudanças climáticas pode ser resolvido por engenheiros.

O que geralmente divide as posições ideológicas não é a fé na tecnologia como tal, mas quais soluções técnicas escolher, e se exigirão mudanças políticas importantes. Aqueles que permanecem céticos em relação às promessas da tecnologia - como os defensores da redução radical ou decrescimento - tendem a ser marginalizados da política e da mídia. Até aqui, qualquer político que defenda seriamente o decrescimento provavelmente não terá futuro na política.

O otimismo dominante em relação à tecnologia costuma ser chamado de ecomodernismo. O Manifesto Ecomodernista, uma declaração concisa dessa abordagem publicada em 2015, nos pede para abraçar o progresso tecnológico, que nos dará "uma boa, ou até ótimo, Antropoceno ". Argumenta que o progresso da tecnologia nos" desvinculou "do mundo natural e deve ser permitido que continuemos a fazê-lo, a fim de permitir o" rewilding "da natureza. O crescimento das cidades, agricultura industrial, e energia nuclear, afirma, ilustram tal desacoplamento. Como se esses fenômenos não tivessem pegadas ecológicas além de seus próprios limites.

Enquanto isso, apelos por um Novo Acordo Verde têm sido feitos há mais de uma década, mas em fevereiro de 2019 tomou a forma de uma resolução para a Câmara dos Representantes americana. O ponto central de sua visão é uma mudança em grande escala para fontes de energia renováveis ​​e investimentos maciços em nova infraestrutura. Isso permitiria um maior crescimento da economia, é argumentado.

Repensando a tecnologia

Portanto, o consenso geral parece ser que o problema da mudança climática é apenas uma questão de substituir uma tecnologia de energia por outra. Mas uma visão histórica revela que a própria ideia de tecnologia está inextricavelmente entrelaçada com a acumulação de capital, troca desigual e a ideia de dinheiro para todos os fins. E como tal, não é tão fácil redesenhar como gostamos de pensar. Mudar a principal tecnologia de energia não é apenas uma questão de substituir a infraestrutura - significa transformar a ordem econômica mundial.

No século 19, a revolução industrial nos deu a noção de que o progresso tecnológico é simplesmente engenhosidade humana aplicada à natureza, e que não tem nada a ver com a estrutura da sociedade mundial. Esta é a imagem espelhada da ilusão dos economistas, que o crescimento nada tem a ver com a natureza e, portanto, não precisa levar em conta os limites naturais. Em vez de ver que tanto a tecnologia quanto a economia abrangem a divisão entre natureza e sociedade, a engenharia é considerada como lidando apenas com a natureza e a economia como lidando apenas com a sociedade.

O motor a vapor, por exemplo, é simplesmente considerada uma invenção engenhosa para aproveitar a energia química do carvão. Não estou negando que este seja o caso, mas a tecnologia a vapor no início da Grã-Bretanha industrial também dependia do capital acumulado nos mercados globais. As fábricas movidas a vapor em Manchester nunca teriam sido construídas sem o comércio atlântico triangular de escravos, algodão cru, e têxteis de algodão. A tecnologia Steam não era apenas uma questão de engenharia engenhosa aplicada à natureza, como toda tecnologia complexa, também era crucialmente dependente das relações globais de troca.

Essa dependência da tecnologia nas relações sociais globais não é apenas uma questão de dinheiro. Em um sentido bastante físico, a viabilidade da máquina a vapor dependia dos fluxos de energia do trabalho humano e outros recursos que haviam sido investidos na fibra de algodão da Carolina do Sul, nos E.U.A, carvão do País de Gales e ferro da Suécia. Tecnologia moderna, então, é um produto do metabolismo da sociedade mundial, não simplesmente o resultado da descoberta de "fatos" da natureza.

A ilusão que temos sofrido desde a revolução industrial é que a mudança tecnológica é simplesmente uma questão de conhecimento de engenharia, independentemente dos padrões de fluxos globais de materiais. Isso é particularmente problemático porque nos torna cegos para como esses fluxos tendem a ser altamente desiguais.

This is not just true of the days of the British Empire. To this day, technologically advanced areas of the world are net importers of the resources that have been used as inputs in producing their technologies and other commodities, such as land, trabalho, materiais, e energia. Technological progress and capital accumulation are two sides of the same coin. But the material asymmetries in world trade are invisible to mainstream economists, who focus exclusively on flows of money.

Ironicamente, this understanding of technology is not even recognized in Marxist theory, although it claims to be both materialist and committed to social justice. Marxist theory and politics tend toward what opponents refer to as a Promethean faith in technological progress. Its concern with justice focuses on the emancipation of the industrial worker, rather than on the global flows of resources that are embodied in the industrial machine.

This Marxist faith in the magic of technology occasionally takes extreme forms, as in the case of the biologist David Schwartzman, who does not hesitate to predict future human colonization of the galaxy and Aaron Bastani, who anticipates mining asteroids. In his remarkable book Fully Automated Luxury Communism:A Manifesto, Bastani repeats a widespread claim about the cheapness of solar power that shows how deluded most of us are by the idea of technology.

Nature, ele escreve, "provides us with virtually free, limitless energy." This was a frequently voiced conviction already in 1964, when the chemist Farrington Daniels proclaimed that the "most plentiful and cheapest energy is ours for the taking." More than 50 years later, the dream persists.

The realities

Electricity globally represents about 19% of total energy use—the other major energy drains being transports and industry. Em 2017, only 0.7% of global energy use derived from solar power and 1.9% from wind, while 85% relied on fossil fuels. As much as 90% of world energy use derives from fossil sources, and this share is actually increasing. So why is the long-anticipated transition to renewable energy not materializing?

One highly contested issue is the land requirements for harnessing renewable energy. Energy experts like David MacKay and Vaclav Smil have estimated that the "power density"—the watts of energy that can be harnessed per unit of land area—of renewable energy sources is so much lower than that of fossil fuels that to replace fossil with renewable energy would require vastly greater land areas for capturing energy.

In part because of this issue, visions of large-scale solar power projects have long referred to the good use to which they could put unproductive areas like the Sahara desert. But doubts about profitability have discouraged investments. Uma década atrás, por exemplo, there was much talk about Desertec, a €400 billion project that crumbled as the major investors pulled out, um por um.

Today the world's largest solar energy project is Ouarzazate Solar Power Station in Morocco. It covers about 25 square kilometres and has cost around US$9 billion to build. It is designed to provide around a million people with electricity, which means that another 35 such projects—that is, US$315 billion of investments—would be required merely to cater to the population of Morocco. We tend not to see that the enormous investments of capital needed for such massive infrastructural projects represent claims on resources elsewhere—they have huge footprints beyond our field of vision.

Também, we must consider whether solar is really carbon free. As Smil has shown for wind turbines and Storm van Leeuwen for nuclear power, a produção, installation, and maintenance of any technological infrastructure remains critically dependent on fossil energy. Claro, it is easy to retort that until the transition has been made, solar panels are going to have to be produced by burning fossil fuels. But even if 100% of our electricity were renewable, it would not be able to propel global transports or cover the production of steel and cement for urban-industrial infrastructure.

And given the fact that the cheapening of solar panels in recent years to a significant extent is the result of shifting manufacture to Asia, we must ask ourselves whether European and American efforts to become sustainable should really be based on the global exploitation of low-wage labor, scarce resources and abused landscapes elsewhere.

Collecting carbon

Solar power is not displacing fossil energy, only adding to it. And the pace of expansion of renewable energy capacity has stalled – it was about the same in 2018 as in 2017. Meanwhile, our global combustion of fossil fuels continues to rise, as do our carbon emissions. Because this trend seems unstoppable, many hope to see extensive use of technologies for capturing and removing the carbon from the emissions of power plants and factories.

Carbon Capture and Storage (CCS) remains an essential component of the 2016 Paris Agreement on climate change. But to envisage such technologies as economically accessible at a global scale is clearly unrealistic.

To collect the atoms of carbon dispersed by the global combustion of fossil fuels would be as energy-demanding and economically unfeasible as it would be to try to collect the molecules of rubber from car tires that are continuously being dispersed in the atmosphere by road friction.

The late economist Nicholas Georgescu-Roegen used this example to show that economic processes inevitably lead to entropy—that is, an increase in physical disorder and loss of productive potential. In not grasping the implications of this fact, we continue to imagine some miraculous new technology that will reverse the Law of Entropy.

Economic "value" is a cultural idea. An implication of the Law of Entropy is that productive potential in nature—the force of energy or the quality of materials—is systematically lost as value is being produced. This perspective turns our economic worldview upside down. Value is measured in money, and money shapes the way we think about value. Economists are right in that value should be defined in terms of human preferences, rather than inputs of labor or resources, but the result is that the more value we produce, the more inexpensive labor, energy and other resources are required. To curb the relentless growth of value—at the expense of the biosphere and the global poor—we must create an economy that can restrain itself.

The evils of capitalism

Much of the discussion on climate change suggests that we are on a battlefield, confronting evil people who want to obstruct our path to an ecological civilization. But the concept of capitalism tends to mystify how we are all caught in a game defined by the logic of our own constructions—as if there was an abstract "system" and its morally despicable proponents to blame. Rather than see the very design of the money game as the real antagonist, our call to arms tends to be directed at the players who have had best luck with the dice.

I would instead argue that the ultimate obstruction is not a question of human morality but of our common faith in what Marx called "money fetishism." We collectively delegate responsibility for our future to a mindless human invention—what Karl Polanyi called all-purpose money, the peculiar idea that anything can be exchanged for anything else. The aggregate logic of this relatively recent idea is precisely what is usually called "capitalism." It defines the strategies of corporations, políticos, and citizens alike.

All want their money assets to grow. The logic of the global money game obviously does not provide enough incentives to invest in renewables. It generates greed, obscene and rizing inequalities, violence, and environmental degradation, incluindo as alterações climáticas. But mainstream economics appears to have more faith in setting this logic free than ever. Given the way the economy is now organized, it does not see an alternative to obeying the logic of the globalized market.

The only way to change the game is to redesign its most basic rules. To attribute climate change to an abstract system called capitalism—but without challenging the idea of all-purpose money—is to deny our own agency. The "system" is perpetuated every time we buy our groceries, regardless of whether we are radical activists or climate change deniers. It is difficult to identify culprits if we are all players in the same game. In agreeing to the rules, we have limited our potential collective agency. We have become the tools and servants of our own creation—all-purpose money.

Despite good intentions, it is not clear what Thunberg, Extinction Rebellion and the rest of the climate movement are demanding should be done. Like most of us, they want to stop the emissions of greenhouse gases, but seem to believe that such an energy transition is compatible with money, globalized markets, and modern civilization.

Is our goal to overthrow "the capitalist mode of production"? Se então, how do we go about doing that? Should we blame the politicians for not confronting capitalism and the inertia of all-purpose money? Or—which should follow automatically—should we blame the voters? Should we blame ourselves for not electing politicians that are sincere enough to advocate reducing our mobility and levels of consumption?

Many believe that with the right technologies we would not have to reduce our mobility or energy consumption—and that the global economy could still grow. But to me that is an illusion. It suggests that we have not yet grasped what "technology" is. Electric cars and many other "green" devices may seem reassuring but are often revealed to be insidious strategies for displacing work and environmental loads beyond our horizon—to unhealthy, low-wage labor in mines in Congo and Inner Mongolia. They look sustainable and fair to their affluent users but perpetuate a myopic worldview that goes back to the invention of the steam engine. I have called this delusion machine fetishism.

Redesigning the global money game

So the first thing we should redesign are the economic ideas that brought fossil-fueled technology into existence and continue to perpetuate it. "Capitalism" ultimately refers to the artifact or idea of all-purpose money, which most of us take for granted as being something about which we do not have a choice. But we do, and this must be recognized.

Since the 19th century, all-purpose money has obscured the unequal resource flows of colonialism by making them seem reciprocal:money has served as a veil that mystifies exploitation by representing it as fair exchange. Economists today reproduce this 19th-century mystification, using a vocabulary that has proven useless in challenging global problems of justice and sustainability. The policies designed to protect the environment and promote global justice have not curbed the insidious logic of all-purpose money—which is to increase environmental degradation as well as economic inequalities.

In order to see that all-purpose money is indeed the fundamental problem, we need to see that there are alternative ways of designing money and markets. Like the rules in a board game, they are human constructions and can, em princípio, be redesigned. In order to accomplish economic "degrowth" and curb the treadmill of capital accumulation, we must transform the systemic logic of money itself.

National authorities might establish a complementary currency, alongside regular money, that is distributed as a universal basic income but that can only be used to buy goods and services that are produced within a given radius from the point of purchase. This is not "local money" in the sense of LETS or the Bristol Pound – which in effect do nothing to impede the expansion of the global market—but a genuine spanner in the wheel of globalization. With local money you can buy goods produced on the other side of the planet, as long as you buy it in a local store. What I am suggesting is special money that can only be used to buy goods produced locally.

This would help decrease demand for global transports—a major source of greenhouse gas emissions—while increasing local diversity and resilience and encouraging community integration. It would no longer make low wages and lax environmental legislation competitive advantages in world trade, as is currently the case.

Immunizing local communities and ecosystems from the logic of globalized capital flows may be the only feasible way of creating a truly "post-capitalist" society that respects planetary boundaries and does not generate deepening global injustices.

Re-localizing the bulk of the economy in this way does not mean that communities won't need electricity, por exemplo, to run hospitals, computers and households. But it would dismantle most of the global, fossil-fueled infrastructure for transporting people, groceries and other commodities around the planet.

This means decoupling human subsistence from fossil energy and re-embedding humans in their landscapes and communities. In completely changing market structures of demand, such a shift would not require anyone—corporations, políticos, or citizens—to choose between fossil and solar energy, as two comparable options with different profit margins.

To return to the example of Morocco, solar power will obviously have an important role to play in generating indispensable electricity, but to imagine that it will be able to provide anything near current levels of per capita energy use in the global North is wholly unrealistic. A transition to solar energy should not simply be about replacing fossil fuels, but about reorganizing the global economy.

Solar power will no doubt be a vital component of humanity's future, but not as long as we allow the logic of the world market to make it profitable to transport essential goods halfway around the world. The current blind faith in technology will not save us. For the planet to stand any chance, the global economy must be redesigned. The problem is more fundamental than capitalism or the emphasis on growth:it is money itself, and how money is related to technology.

Climate change and the other horrors of the Anthropocene don't just tell us to stop using fossil fuels—they tell us that globalization itself is unsustainable.
