Cuba’s energy crisis is no longer just an inconvenience or a political talking point. In the spring of 2026, it had become one of the most acute humanitarian emergencies in the Western Hemisphere, unfolding in plain sight on an island of 11 million people who have almost no way to leave and almost no way to make it stop.
Power cuts on the island now last up to 20 to 22 hours a day in the worst-affected areas. The national electrical grid has collapsed completely on multiple occasions. Hospitals are running on generators that may or may not have fuel. Garbage trucks sit idle because there is nothing to run them. Schools and universities are closed. Air Canada, Rossiya Airlines, and Nordwind have all suspended flights to the island, citing the inability to refuel aircraft. The country, according to data from the Kpler energy analytics firm, had enough oil reserves on January 30, 2026, to last approximately 15 to 20 days at normal consumption levels. That was months ago.
What is happening in Cuba is not a single crisis but the convergence of several, and understanding how they combine requires looking at each one separately.
The Collapse of Cuba’s Energy Supply Chain
Cuba’s energy dependency has always been its central strategic vulnerability. The country produces only about 40% of its oil needs domestically. The rest has historically come from external suppliers willing to provide oil on favorable terms for political or economic reasons.
Venezuela was the cornerstone of that arrangement for more than two decades, supplying Cuba with subsidized oil under agreements that dated to the early 2000s relationship between Hugo Chavez and Fidel Castro. At peak, Venezuela sent up to 46,500 barrels per day to Cuba. By 2025, that number had fallen to approximately 26,500 barrels per day as Venezuela’s own production declined. When the United States intervened in Venezuela and Nicolas Maduro was removed from power in late 2025, Venezuelan shipments to Cuba stopped entirely.
Mexico had filled some of the gap, at one point supplying nearly 44% of Cuba’s total oil imports. In January 2026, under sustained US pressure, including threats of tariffs against countries supplying Cuba with oil, Mexico halted shipments. Russian deliveries, which had provided approximately 10% of Cuba’s imports, stopped in October 2025.
By February 2026, Cuba’s oil import tap had been reduced to nearly zero. The country’s eight thermal power plants, already more than 40 years old and severely undermaintained, cannot run without fuel. As of Easter Sunday 2026, Cuba’s National Electric System was generating approximately 1,278 megawatts against a maximum demand of roughly 3,000 megawatts a deficit of over 1,700 megawatts. Nine thermal plant units were out of service due to breakdowns and fuel shortages.
A March 2026 report by the Cuba Study Group estimated that at least $6.6 billion in new generation investment alone would be needed to close the structural gap, not including transmission, distribution, or storage modernization. Cuba does not have $6.6 billion. It does not have access to international financing capable of providing it. And even if it did, the infrastructure of that scale takes years to build.
What This Means for People on the Ground
The numbers describe a scale of deprivation that is difficult to translate into the texture of daily life. These details begin to do that.
Residents of Havana and other cities have reported charging mobile phones during brief windows of power. Cooking is done outdoors over wood and charcoal, pooled communally when neighbors share what little they have. Food refrigeration has failed across the island, spoiling perishable supplies in a country already experiencing widespread food shortages. According to the Food Monitor Program, 33.9% of Cuban households reported hunger in 2025. That figure was recorded before the worst of the 2026 fuel collapse.
Healthcare is operating under extreme duress. Hospitals rely on generators that depend on diesel supplies that may or may not arrive. Water pumping systems require electricity. Without reliable power, basic sanitation in dense urban areas becomes a serious public health risk on a timeline measured in weeks, not months.
The protests that began as localized pot-banging demonstrations have grown. The Cuban Observatory of Conflicts recorded 1,133 protests in April 2026, a 29.5% increase compared to April 2025. The government’s response has been militarization and arrests. At least 14 individuals were detained in Havana in connection with demonstrations in March 2026. Fires have been reported in residential neighborhoods of the capital as a result of unrest. “You’re starting to see the breakdown of social order,” said William LeoGrande, a professor of government at American University and specialist in US-Cuban relations, speaking to ABC News.

The Geopolitical Dimension: Sanctions, Blockade, and Blame
No serious account of Cuba’s energy crisis can avoid the political dimension, and no serious account can reduce the crisis to politics alone.
The United States tightened its economic sanctions against Cuba significantly in January 2025, within hours of Donald Trump’s return to office. The sanctions were framed as part of a maximum pressure strategy targeting the Cuban government’s human rights record and its relationship with Venezuela. In December 2025, as part of the escalating pressure surrounding the Venezuela intervention, the United States seized tankers carrying Venezuelan oil to Cuba and declared a blockade on Venezuelan oil exports to the island.
The Cuban government’s position is consistent and unambiguous: the US blockade, in place in various forms since 1960 and tightened repeatedly, is the primary cause of the current crisis. Cuban officials describe the energy collapse as a direct result of deliberate American policy designed to destabilize the government.
The US government’s position is equally consistent: sanctions are a response to Cuba’s authoritarian governance and human rights violations, and the humanitarian crisis reflects the failure of the Cuban government’s economic model rather than the impact of external pressure. Secretary of State Marco Rubio announced new sanctions on May 7, 2026, against the Cuban military conglomerate GAESA and 12 regime officials, while simultaneously offering $100 million in conditional humanitarian aid.
Independent analysts are more nuanced. Cuba’s oil-powered electrical infrastructure is more than 40 years old and has undergone minimal capital maintenance. The reliance on subsidized Venezuelan oil was a structural vulnerability that Cuban economic policy never addressed. As Jorge Piñon, director of the Latin America and Caribbean Energy Program at the University of Texas at Austin’s Energy Institute, told ABC News: “Cuba’s oil-run electric power plants are more than 40 years old and have undergone very little capital maintenance.” The existing structural problems, Piñon said, have now been compounded by the punitive actions of the current US administration.
Both things can be true simultaneously. A country can have a fragile, poorly maintained energy infrastructure built on an unsustainable dependency on subsidized imports, and that country can also be experiencing an acute crisis that is materially worsened by external pressure. The two are not mutually exclusive, and the political argument over which is primary does not change the conditions facing 11 million people without reliable power, food security, or a clear path to improvement.
The Al Jazeera explainer on the US blockade’s impact on Cuban daily life provides detailed context on how the supply chain collapse has affected ordinary Cubans, drawing on reporting from inside the country.
This intersection of economic vulnerability, geopolitical pressure, and humanitarian consequence reflects dynamics explored in how trade policy decisions produce cascading effects on populations far removed from the political calculations that drive them.
The International Response and Its Limits
The international community has responded to Cuba’s crisis in ways that reflect the geopolitical divisions surrounding it rather than a unified humanitarian framework.
Canada announced C$8 million in funding for food and nutrition programs, with an additional C$5.5 million announced subsequently. Brazil’s President Luiz Inácio Lula da Silva condemned the US fuel blockade and called for humanitarian assistance. Chile’s then-current president, Gabriel Boric, described the blockade as criminal and inhumane. Mexico, despite halting oil shipments under US pressure, sent two ships of humanitarian aid in February 2026.
The United Nations has been among the most direct voices on the urgency of the situation. UN Secretary-General Antonio Guterres expressed extreme concern through his spokesman, stating that the humanitarian situation in Cuba “will worsen, and if not collapse, if its oil needs go unmet.” The UN’s senior official in Cuba, Francisco Pichon, described a country experiencing “a mix of resilience, but also grief, sorrow, and indignation.” The UN has consistently called for more than three decades for an end to the US embargo.
A Russian oil shipment was allowed to dock despite the US blockade, providing limited relief. The United States, while maintaining sanctions, has offered $100 million in humanitarian aid that Cuba has been reluctant to accept under conditions that the Cuban government views as interfering with its sovereignty.
The United Nations humanitarian update on Cuba’s energy crisis, published in April 2026, documents the persistent nature of the humanitarian needs despite limited fuel deliveries and calls urgently for international support.
The problem with the international response is not its absence; it is its insufficiency relative to the scale of the need. Cuba requires a minimum of eight fuel shipments per month to maintain basic functionality of its power grid. As of early 2026, it was receiving a fraction of that. Humanitarian aid packages address specific needs at the margins. They do not solve a structural energy deficit of 1,700 megawatts.
The Emigration Crisis That Is Already Underway
Cuba’s population has been leaving in record numbers for several years. The fuel crisis has accelerated a trend that was already reshaping the island’s demographic reality.
Between 2022 and 2024, more than half a million Cubans, roughly 5% of the island’s total population, left for the United States, representing the largest migration wave from Cuba in the island’s history. The pace has not slowed. Nicaragua’s cancellation of visa-free travel for Cubans in February 2026, widely understood as a response to US pressure on the Ortega government, closed one of the primary migration routes that had been used by thousands of Cubans since 2021.
The people who are leaving are disproportionately young, educated, and economically mobile, the same demographic that any country attempting economic recovery needs most. The structural effect of sustained emigration on Cuba’s capacity to maintain even its existing, broken infrastructure is significant. An island that is losing its engineers, doctors, and skilled workers faster than it can train replacements is an island with a diminishing capacity to rebuild.
This pattern of population loss compounding institutional fragility connects to broader dynamics of how declining and displaced populations reshape the political and economic futures of the countries they leave behind.
What Comes Next
The honest answer is that the outlook for Cuba in the near term is bleak, and the range of plausible scenarios is narrow.
A diplomatic resolution between Washington and Havana that allows oil imports to resume would be the fastest path to relief for ordinary Cubans. Trump has indicated a willingness to make a deal but has provided no clarity on what that means in practice. The Cuban government has shown no signs of making the political concessions that would satisfy the stated US conditions. The two sides are not in direct negotiation.
In the absence of a diplomatic resolution, Cuba is dependent on the willingness of countries willing to absorb the risk of US secondary sanctions to send fuel. Russia has demonstrated some willingness. Other potential suppliers face significant economic disincentives.
The infrastructure problem is separate and would persist even if the fuel supply were restored tomorrow. Aging power plants that have been running beyond their operational lives, on insufficient fuel, with deferred maintenance, will continue to fail. Restoring Cuba’s electricity grid to a functional state would require years and billions of dollars of investment that the country does not have access to.
For the 11 million people living through this crisis, none of those longer-term calculations change the immediate reality of a country where the lights may not come on for most of the day, where food is spoiling, where hospitals are struggling, and where the government that is supposed to manage the situation has neither the resources nor, increasingly, the political legitimacy to do so.
The crisis connects to how the concentration of power and the absence of diverse institutional checks shape the capacity of states to respond when multiple failures compound simultaneously.
Cuba’s energy crisis is a warning about what happens when energy dependency, infrastructure neglect, geopolitical exposure, and political rigidity collide at the same moment. It is also, more simply, 11 million people living through something that should not be happening.
