Is it possible to produce food without sunlight? "Electricity-powered agriculture" could potentially change "world hunger."

Is it possible to produce food without sunlight? "Electricity-powered agriculture" could potentially change "world hunger."

The term "food crisis" is no longer just news from distant countries. Extreme heat, droughts, floods, geopolitical risks, and fluctuating fertilizer prices. While fields are places that face nature, they have now become "devices that bear the brunt of climate and economic shocks."


Amidst this, a seemingly science fiction-like proposal has emerged: the idea that "we might be able to produce food without light." Greek media outlet GreekReporter introduced the concept of "electro-agriculture," which aims to reorganize food production without relying on traditional photosynthesis. Estimates suggest it could reduce the need for farmland by up to 94%, mitigate the impacts of extreme weather, and prevent sharp increases in food prices.


What is "electro-agriculture"? — Bypassing the "bottleneck of photosynthesis"

The key is to change how crops extract energy for growth. Traditionally, plants perform photosynthesis by absorbing sunlight to create organic compounds like sugars from CO₂ and water. However, it is known that photosynthesis has a low conversion rate of solar energy into crop growth.


The idea behind electro-agriculture is this: use electricity derived from renewable energy to electrochemically convert CO₂ into "acetate." Acetate is an organic molecule that can be used as a nutrient by microorganisms and some organisms. Researchers treat this as the "raw material for food made with electricity." In the future, crops could be genetically modified to grow using acetate without relying on photosynthesis — this is the broad outline.


According to the GreekReporter article, this framework combines CO₂ electrolysis with biological systems to bypass the efficiency constraints of photosynthesis. The research also suggests that food production could become possible in non-agricultural areas like "deserts," "urban centers," and "space."


The impact of "94% farmland reduction" — Could it be the answer to land, water, and climate risks?

The true significance of this technology (or group of technologies) lies not just in increased yields. It is because the bottleneck of society is shifting to "land, water, and climate."


The article mentions estimates that if the food system fully transitions to an electro-agriculture base, farmland use in the United States could decrease by 88-90%, potentially allowing nearly half of the country's land to be allocated for ecosystem restoration and natural carbon absorption.

 
Additionally, by shifting towards "engineered controlled production" less susceptible to extreme weather, the aim is to stabilize yields and prevent price spikes.


The important point here is not to increase farmland but to "increase the proportion that does not require farmland." As disasters and climate fluctuations become more severe, food supply is strongly constrained by "geography." If a certain amount of food can be produced near cities or indoors, as long as energy and CO₂ are secured, it reduces the risks of logistics disruptions and import dependency. This is not only a climate adaptation measure but also relates to security.


However, this is not a story of "farms disappearing now" — the current state of research

It is important not to misunderstand that this is a completed technology ready to replace agriculture starting tomorrow. GreekReporter refers to a proposal (perspective/concept proposal) published in Joule, which strongly indicates future implementation scenarios and research challenges.


Currently, there are at least three key aspects.

  1. Efficiency and cost of CO₂ to acetate conversion (improvement of electrochemical conversion)

  2. Design for crops to utilize acetate (challenges in genetic modification and metabolic pathway optimization)

  3. System integration (how to organize power, CO₂ capture, cultivation environment, sanitation, and supply chain)


Furthermore, the potential application of acetate in fermentation (precision fermentation) and cultured meat as protein sources, not just "crops themselves," is also mentioned.

 
In other words, electro-agriculture is closer to a "concept for electrifying and decentralizing the food system" rather than just a "new technology for growing vegetables."


Reactions on social media: Expectations run high, but doubts are also strong

When this topic spreads on social media, reactions generally fall into three categories. Indeed, in academic journal introduction posts (such as those by Cell Press on social media), the catchy phrase "Growing food in the dark" stands out, leading to surprise and excitement.


① "This is the breakthrough" group (expectation)

  • The more unstable arable land becomes due to climate change, the more valuable indoor, urban, and decentralized production becomes.

  • If farmland can be reduced, it might be possible to allocate it for forest recovery and biodiversity restoration.

  • It could become a "game-changer" for regions with strong land and water constraints, such as desert nations and island countries.
    Such voices are easily received as a story that breaks the premise of "food = land."


② "But doesn't it require electricity and facilities?" group (reality)

  • Isn't the food problem more severe in regions where electricity is unstable?

  • If large facilities and CO₂ supply are needed, wouldn't it favor countries and companies with capital?

  • If the energy source is fossil fuels, wouldn't it just transfer environmental burdens in another form?
    This group focuses more on the "political economy of implementation" than the technology itself. They calmly point out that even if "farmland" decreases, "infrastructure" will still be needed, including electricity, facilities, maintenance, and supply chains.


③ "Genetically modified crops? That's impossible" group (ethics and acceptance)
Electro-agriculture is often inseparable from the discussion of adapting crops to utilize acetate, which can easily spark debates about genetic modification (GMO) aversion. On social media, there is a certain number of opinions that say, "The technology is interesting, but food acceptance is a separate issue." This is more about the design of "transparency, regulation, labeling, and trust" than a matter of pros and cons.


Summarizing the atmosphere on social media, it doesn't end with just "it seems amazing." The initial surprise quickly shifts to discussions on "electricity, cost, equity, and acceptance." This is indeed a typical diffusion pattern for next-generation technologies.

The real question is the scope that "electrification of food" can save

The discussion of electro-agriculture is often talked about as a "replacement for fields." However, in reality, "complementation" will likely come first rather than replacement.

  • Backup production in regions frequently hit by climate disasters

  • Strategic decentralized supply for countries highly dependent on imports

  • Niche applications in areas where traditional agriculture is disadvantaged, such as arid regions, cold regions, and polar night areas

  • Expansion of food groups with low land dependency, such as fermentation proteins

And another aspect not to be forgotten is the fertilizer issue. Modern agriculture heavily relies on nitrogen fertilizers, and their production is directly linked to energy and CO₂ emissions issues. The trend of electrifying and decentralizing agriculture is also compatible with the "electrification" of fertilizers (for example, research on nitrogen fixation using plasma).

 
If we view the food crisis as a chain involving "fertilizers, energy, and logistics" rather than just "fields," electro-agriculture should be evaluated as an attempt to reorganize that chain.

The future is not "zero fields" but "risk diversification"

In conclusion, electro-agriculture is not "the only answer to save the global food crisis." However, the direction of "not relying solely on nature for food production as the climate becomes more unstable" is gaining persuasiveness.


Fields will not disappear. Farmers will not become unnecessary. Rather, combining agriculture that faces nature, controlled indoor production, fermentation and cell culture, alternative proteins, and resource-saving distribution to create "redundancy" where food does not stop even if something breaks is realistic.


The simultaneous eruption of enthusiasm and skepticism on social media is likely because this technology shakes the "blueprint of society" more than just being an "amazing invention."


Electro-agriculture is the idea of liberating food from the sun. However, the real challenge lies in whether food can be liberated from "vulnerable centralized points."
