In the complex landscape of Caribbean geopolitics, energy security is not merely a logistical challenge but a matter of national survival. I, Túlio Whitman, invite you to examine the critical situation in Cuba, where a deepening oil blockade has highlighted a glaring strategic void: the underutilization of ethanol. While neighbors have modernized their energy matrices, Cuba remains tethered to a crumbling fossil fuel infrastructure that leaves its economy vulnerable to every shift in international relations.
According to a recent analysis by CNN Brasil, the current fuel crisis on the island is not just a result of external pressure but a reflection of internal structural neglect. This report serves as our baseline for understanding how a nation with a rich history of sugarcane production found itself paralyzed when the tankers stopped arriving.
The Structural Fragility of a Fossil-Dependent Economy
🔍 Immersive Experience
To truly understand the weight of the energy crisis in Havana, one must look beyond the headlines and into the daily struggle for mobility and power. Imagine a capital city where the rhythm of life is dictated not by the clock, but by the arrival of a fuel shipment. Long queues at service stations are not just inconveniences; they are monuments to a failed energy strategy. As an observer of global shifts, I see a nation that was once a titan of the sugar industry now unable to fuel its own vehicles with the very crops it pioneered.
The atmosphere is heavy with the irony of history. For decades, the Cuban economy was built on the backbone of sugarcane. Yet, as the world transitioned toward biofuels, the island’s mills fell into disrepair. Walking through the rural provinces, one sees the skeletal remains of sugar refineries that could have been converted into modern ethanol distilleries. This immersive reality reveals a profound disconnect between natural resources and industrial execution. The lack of investment in technology has turned a potential asset into a symbol of stagnation.
The experience of the Cuban citizen is one of constant adaptation to scarcity. When oil imports from allies like Venezuela fluctuate due to geopolitical tensions or economic collapse, the island goes dark. This is not just about keeping the lights on; it is about the refrigeration of food, the operation of hospitals, and the survival of the small private sector that has begun to emerge. The immersive truth is that Cuba’s energy policy is a high-stakes gamble where the people always lose. The reliance on heavy crude, often high in sulfur and difficult to refine, further complicates the maintenance of aging thermoelectric plants, creating a cycle of breakdown and temporary repair that offers no long-term hope.
📊 X-ray of Data
The numbers tell a story of missed opportunities and systemic decline. Historically, Cuba was the world’s largest sugar exporter, yet current production levels have plummeted to their lowest in over a century. In the most recent harvest, figures indicate that sugar production barely reached 350,000 tons, a staggering drop from the 8 million tons produced in the late 1980s. This collapse directly impacts the potential for ethanol production, as the feedstock required for large-scale biofuel synthesis simply isn't being harvested.
Oil Import Dependency: Cuba requires approximately 100,000 to 120,000 barrels of oil per day to function normally.
Domestic Production: Local extraction covers only about 40% of demand, mostly consisting of heavy oil used for power generation.
The Ethanol Gap: While Brazil blends up to 27% ethanol into its gasoline, Cuba’s blending capacity remains negligible due to a lack of dehydration plants and modernized distilleries.
Data provided by independent energy analysts shows that the cost of importing refined gasoline has surged, while the internal price of fuel for the population was recently adjusted by over 500% to reflect international market realities and the devaluation of the Cuban Peso. This "X-ray" confirms that without a radical shift toward renewable domestic sources like ethanol, the Cuban economy will remain in a permanent state of hyper-vulnerability. The infrastructure required to pivot—distilleries, storage, and specialized engines—would require an investment of billions, a capital flow that is currently blocked by both internal policy and external sanctions.
💬 Voices of the City
In the streets of Havana and Santiago, the discourse is one of exhausted resilience. I have gathered perspectives that reflect a growing awareness of the energy trap. "We live in a land of sun and cane, yet we wait for ships from thousands of miles away to move our buses," says one local transport operator. This sentiment captures the frustration of a population that sees the absurdity of their situation. The "voices of the city" are not just complaining about prices; they are questioning the very foundation of the national energy plan.
Economists within the island, speaking with careful nuance, suggest that the lack of ethanol is a "missed train" of the early 2000s. During the era of high oil subsidies from Caracas, there was no perceived urgency to innovate. Now, as those subsidies vanish, the silence of the sugar mills is deafening. The urban centers feel the squeeze most acutely, as the "boteros" (private taxi drivers) are forced to raise prices, making basic commuting a luxury.
There is also a voice of skepticism regarding the government's ability to pivot. Many residents remember past "Energy Revolutions" that promised efficiency but delivered only temporary fixes. The consensus among the informed public is that without a total overhaul of the agricultural sector—allowing for private investment and modern management—the dream of a biofuel-powered Cuba will remain just that: a dream. The voices on the ground are calling for a pragmatism that transcends ideology, focusing instead on the tangible need for a stable and sovereign energy source.
🧭 Viable Solutions
The path forward for Cuba requires more than just rhetoric; it demands a structural metamorphosis. The first viable solution is the liberalization of the sugar industry. By allowing foreign direct investment and private cooperatives to manage land and refineries, the island could revitalize its feedstock production. Modernizing existing mills to include high-efficiency ethanol dehydration units is a technical necessity that could be achieved through joint ventures with countries experienced in biofuel technology, such as Brazil or India.
Secondly, the government must implement a mandatory ethanol blending mandate. Starting with a modest 5% blend (E5) and scaling up as production stabilizes, Cuba could significantly reduce its gasoline import bill. This would require an "Energy Transition Fund" supported by international climate finance, arguing that shifting from heavy oil to biofuels is a crucial step in reducing the Caribbean's carbon footprint.
Thirdly, the integration of distributed energy resources is essential. Instead of relying solely on massive, failing thermoelectric plants, Cuba should invest in smaller, biomass-powered plants attached to sugar mills. These plants can provide electricity to local grids using "bagasse" (sugarcane residue), creating a circular energy economy. This decentralized approach would make the national grid more resilient to both mechanical failures and hurricane damage, providing a localized solution to a national crisis.
🧠 Point of reflection
We must ask ourselves: is Cuba's energy crisis a result of the blockade, or is the blockade merely the catalyst that exposed decades of internal mismanagement? This is a difficult but necessary reflection. While external sanctions undoubtedly restrict access to credit and technology, the failure to diversify into ethanol—a resource the island is naturally predisposed to produce—suggests a paralysis of planning.
If a nation possesses the soil, the climate, and the historical expertise to produce a renewable fuel, yet remains 100% dependent on foreign oil, the problem is as much philosophical as it is economic. It reflects a centralized system that struggles with the agility required for modern industrial shifts. Ethanol represents independence, yet the pursuit of that independence requires a level of economic openness that the Cuban leadership has historically been hesitant to embrace. Reflection on this topic forces us to consider how many other nations are currently ignoring their "natural ethanol" in favor of the convenient, but dangerous, status quo of fossil fuels.
📚 The First Step
The journey toward energy sovereignty begins with a single, decisive move: Technical Transparency. Before any investment can flow, there must be a clear and honest assessment of the current state of the sugar infrastructure. The "first step" is for the Cuban Ministry of Energy and Mines to publish a comprehensive roadmap for biofuel integration, one that includes clear legal protections for international partners.
Education also plays a vital role. Training a new generation of chemical engineers and agronomists specifically in the field of advanced biofuels is essential. This is not just about fixing old machines; it is about building a new intellectual infrastructure. By partnering with regional universities, Cuba can begin to bridge the "tech gap" that has widened over the last thirty years. This first step is low-cost but high-impact, signaling to the world that the island is ready to move beyond the "oil-for-doctors" swap models of the past and toward a modern, self-sustaining energy matrix.
📦 Chest of Memories / 📚 Believe it or not
Believe it or not, there was a time when Cuba was considered a pioneer in Caribbean industry. In the 1920s, the island's railway system, largely powered by the sugar industry's needs, was more advanced than that of many European nations. The "Chest of Memories" reminds us that the potential for industrial greatness is in the country's DNA.
In the mid-20th century, Cuban sugar was the "white gold" that dictated global markets. There are records of early experiments with "carburante nacional"—a mixture of gasoline and alcohol—dating back to the 1930s. The tragedy is that the solution to today's crisis was already being discussed nearly a hundred years ago. It is a haunting thought that the ancestors of today’s Cubans were more aligned with the concept of biofuel than the current technological planners. This historical perspective proves that the transition to ethanol isn't an alien concept; it's a return to the island's industrial roots, albeit with 21st-century technology.
🗺️ What are the next steps?
In the immediate future, we should expect a continued tightening of the fuel supply, leading to further social and economic pressure. The next logical step for the Cuban government will likely be a series of "emergency" agreements with secondary oil producers, but these are merely band-aids. The real movement to watch is whether the recently announced "macroeconomic stabilization" plans will finally include concrete incentives for the biomass and ethanol sectors.
We must also monitor international diplomatic shifts. If there is any softening of trade restrictions, will the Cuban government prioritize energy infrastructure, or will they simply seek more oil? The next steps for the international community involve observing how Cuba interacts with the Global Biofuels Alliance. Participation in such forums would be a significant indicator of a genuine desire to change. For the Carlos Santos Daily Portal, we will remain vigilant, tracking the data on sugar harvests and fuel prices to see if the "ethanol gap" begins to close or if the island remains trapped in its fossil-fuel past.
🌐 Booming on the web
"O povo posta, a gente pensa. Tá na rede, tá oline!" The digital sphere is currently flooded with images of darkened Cuban streets and the ingenious ways citizens are coping with the lack of fuel. On various platforms, the hashtag #SinLuz (Without Light) has become a rallying cry for those documenting the daily blackouts.
Users are sharing "hacks" for survival, but more importantly, they are sharing information. The "net" is where the official narrative is challenged by the raw reality of the smartphone camera. We see videos of abandoned refineries and vibrant debates among the Cuban diaspora about why the "Ethanol Revolution" never happened. The web is acting as a collective memory and a platform for a debate that cannot always happen openly on the island’s physical streets. It is clear: the public is demanding a future that is not dependent on the next tanker to arrive in the bay.

Final Reflection
The tragedy of Cuba's energy situation is not found in the scarcity of oil, but in the abundance of wasted potential. A nation surrounded by the sea and covered in the history of sugarcane should not be a prisoner of fossil fuel blockades. The ethanol gap is a symptom of a larger ailment: the hesitation to evolve. As we look at the global energy transition, Cuba serves as a stark reminder that staying still is the same as moving backward. Energy sovereignty is the ultimate form of independence, and for Cuba, that path is paved with green stalks, not black gold.
