The climate crisis is a challenge that threatens the very foundation of our civilization. We find ourselves in a world powered by fossil fuels, a system that has brought us immense benefits but also carries a heavy cost. The negative impacts of fossil fuels, from climate change to air pollution-related deaths, are well-documented. However, the positive aspects of the fossil fuel era, such as electrification, mass production, efficient transportation, and modern agriculture, are often overlooked. These fuels, with their high energy density, have enabled us to build an urban world with steel and cement, transforming our way of life.
The energy required to replicate this abundance is mind-boggling. Fossil fuels, with their 'fossilized sunshine' nature, as historian Alfred Crosby puts it, offer an incredible concentration of energy. Crosby explains that a single gallon of gasoline would require an enormous amount of plant matter or vast acres of grain to produce an equivalent amount of energy. This energy density is a critical factor in our energy choices.
Despite the push for a fossil-free future, we must acknowledge that approximately 80% of the world's energy still comes from fossil fuels. This reality highlights the complexity of the transition and the need for a thorough analysis of alternative energy sources. It is a challenge that brings to mind Karl Marx's thesis on how capitalist social relations can hinder the development of productive forces, a concept relevant to our energy transition.
Many on the left envision a post-fossil fuel world as a simple transition to 'renewables,' primarily solar and wind. However, from a technical perspective, this transition is far more complex. It cannot be achieved solely through variable renewable energy sources.
Nuclear energy, a controversial option, offers an intriguing alternative. With its high energy density, nuclear power has advantages that cannot be ignored when considering the energy needs of a modern society.
Preserving Nuclear Power Plants: A No-Brainer
If climate change is indeed a significant threat, it should be obvious that we should not shut down existing nuclear power plants that provide zero-carbon energy to our grids. This seems like a straightforward decision, yet the left often aligns with environmental groups advocating for the closure of these plants. The shutdown of the Indian Point nuclear plant in New York, for instance, led to the loss of clean energy and well-paying union jobs, deepening the divide between labor and environmentalists. The replacement of this plant's capacity with fossil fuels resulted in a spike in emissions, a clear example of the challenges we face.
The debate on the left should focus on whether we build new nuclear reactors. While Big Tech and political elites support this idea, socialists have unique reasons for advocating for nuclear power. Socialism is about democratizing production, shifting the focus from market competition and profit to production for use and social needs. Nuclear energy, though often criticized for its market costs, has incredible attributes in terms of use value and public good.
Nuclear energy is one of the lowest-carbon energy sources available. While the construction of nuclear plants may require fossil fuels, once built, they can provide zero-carbon power for approximately eighty years. Nuclear energy's high energy density is unparalleled. A pound of uranium can produce the equivalent energy of 2.5 million tons of coal. While uranium mining can be a controversial practice, the amount required for energy production is relatively small, reducing the environmental impact.
Today, uranium mining can be done safely with unionized labor and proper regulation. The concern over 'critical minerals' for the green transition is valid, but nuclear energy requires significantly less mining and materials compared to a renewables-heavy future. Nuclear power's energy density also contributes to its impressive power density, meaning it has the smallest land footprint of any energy source. This not only reduces land conflicts but also allows for more land to be dedicated to conservation and environmental goals.
The left's bias towards solar and wind power has faced political barriers, with local opposition to large-scale renewable energy projects on rural land. A renewables-heavy approach to reach net-zero emissions by 2050 in the US would require massive land use, as indicated by models. Nuclear energy, on the other hand, offers a more efficient land use.
Nuclear energy is also the most reliable power source. Energy experts measure this reliability through the 'capacity factor,' which for nuclear energy is an impressive 92%. In contrast, photovoltaic solar and wind have much lower capacity factors. The sun doesn't always shine, and the wind doesn't always blow, making these sources less reliable and requiring costly backup power or storage.
Nuclear energy is a proven technology. France, for example, achieved nearly 75% carbon-free electricity in just fifteen years, a feat unmatched by any country relying solely on solar and wind. The most decarbonized grids globally are typically a combination of hydro and nuclear power.
Crucially, nuclear energy is widely supported by labor unions in the electricity sector. When green NGOs campaign against nuclear plants, unions fight back, recognizing nuclear power as a source of good jobs and tax revenue for communities. These benefits are public goods that are less easily captured by market forces, highlighting the need for socialism to ensure these benefits are realized.
Addressing Concerns: A Clear-Eyed Approach
The biggest barrier to nuclear energy is the culture of fear surrounding it. Democratic socialists must address these fears head-on if they believe energy technologies should be popular. Proponents of nuclear energy must provide clear responses to the concerns raised.
The issue of nuclear waste is a valid concern. While nuclear energy produces waste that remains unsafe for centuries, it has not caused any harm to date. The amount of waste produced is tiny compared to the energy density of nuclear power. All the nuclear waste created in the US since the 1950s could fit in a single football field. We have the technology to safely store and handle this waste, and even reprocess it into new fuel, as seen in France.
The risk of 'meltdowns' is another concern. Today's nuclear power plant technology has significantly reduced this risk. Even looking at historical examples, the deaths directly caused by nuclear radiation are relatively low compared to other energy sources. Over 99% of deaths from nuclear energy were due to the Chernobyl accident, which occurred in a plant lacking a containment dome, a standard feature in modern plants.
The link between nuclear energy and the nuclear weapons industry is a grave concern. However, this risk exists even without nuclear power. Deploying nuclear energy does not guarantee the development of nuclear weapons. As Leigh Phillips points out, only a fraction of countries with nuclear power have nuclear weapons programs. We must address the threat of nuclear war by vigorously opposing weapons proliferation, but we can do so without sacrificing the benefits of nuclear energy.
In conclusion, a socialist approach to electricity should prioritize abundant, reliable, and low-carbon power. The rapid expansion of nuclear power requires socialism, with public control and socialized investment. The Tennessee Valley Authority and the New York Power Authority, two iconic public power institutions, are pushing for new advanced nuclear reactors. This is a step in the right direction, demonstrating the positive role public power can play in building a clean energy future.
