The Lights Go Out In Havana: How America's Oil Blockade Is Pushing Cuba To The Brink
Imagine a sweltering night in Havana. A family huddles around a single candle. The refrigerator – useless without power – holds spoiled milk for the baby. An elderly neighbor lies awake, fan silent, as temperatures hover near 35°C. Across the island, hospitals have switched to diesel generators that may run out at any moment.
This is not a temporary glitch. It is the new normal.
Since the beginning of 2026, Cuba has been enduring nationwide blackouts stretching 16 to 20 hours a day. In March alone, the country's entire power grid collapsed three times in the space of weeks, leaving millions without electricity for days at a stretch. Oxygen concentrators have failed for the sick. Dialysis patients have missed treatments. Food has rotted. Students have studied by flashlight. Factories have gone idle.
At the center of this unfolding catastrophe sits a decision made in Washington – and a crisis decades in the making.
"The US executive order imposing a fuel blockade on Cuba is a serious violation of international law and a grave threat to a democratic and equitable international order."
– UN Human Rights Experts, February 2026
A Blockade By Any Other Name
The United States has maintained an economic embargo on Cuba since 1962 – one of the longest-running economic sieges in modern history. Washington prefers the word "embargo," framing it as a bilateral trade restriction. The rest of the world, and the majority of international legal experts, call it something closer to a blockade.
The policy's reach extends far beyond a simple ban on US-Cuban commerce. It imposes extraterritorial penalties on third countries and companies that trade with Cuba. Banks processing Cuban transactions risk losing access to the US financial system. Ships docking in Cuban ports face restrictions entering US harbors. Even medical equipment manufacturers can be hit with secondary sanctions.
The result is not a bilateral dispute – it is an economic siege that the international community has repeatedly and overwhelmingly condemned.
At the United Nations General Assembly in October 2025, a resolution calling for an end to the embargo passed 165 votes to 7 – with only the United States, Israel, Argentina, Hungary, Paraguay, North Macedonia, and Ukraine voting against it. It was the 33rd consecutive year the body had passed such a resolution. The near-universal global consensus could not be clearer.
The Tightening Grip – Executive Order 14380
Sanctions did not freeze in 1962. They have been ratcheted up at pivotal moments, and 2026 represents the most severe escalation in a generation.
During his first term, President Donald Trump reversed Obama-era openings, reimposed travel and remittance restrictions, and redesignated Cuba as a State Sponsor of Terrorism in January 2021. The Biden administration kept most measures in place but, in its final hours on January 14, 2025, certified Cuba's removal from the terrorism list and rolled back certain restrictions. Trump, inaugurated six days later, immediately rescinded those changes and reinstated the designation.
Then came Executive Order 14380.
Signed on January 29, 2026, the order imposed tariffs on any country supplying oil to Cuba – effectively launching an oil blockade of the island. Venezuelan shipments, once a critical lifeline accounting for the bulk of Cuba's fuel imports, had already been severed following US military intervention in Venezuela that ousted President Nicolás Maduro. Mexican deliveries halted by late January. Russian fuel, while still trickling in, covers only days of demand.
Cuba's oil imports dropped to near zero in the opening months of 2026.
"Trump tells Cuba to 'make a deal before it is too late,'" read the BBC headline from January 11, 2026. The Wall Street Journal went further, reporting on January 22 that "the US is actively seeking regime change in Cuba by the end of the year."
On February 27, Trump went further still – suggesting the United States could carry out a "friendly takeover" of Cuba.
"This is the United States' first effective blockade of Cuba since the Cuban Missile Crisis."

The Crisis In Brutal Detail
Cuba's National Electric System was already decaying long before 2026. Soviet-era thermoelectric plants – many built in the 1970s and 1980s – are operating past their design life. Domestic crude is heavy and sulfur-laden, corroding equipment faster than it can be repaired. Between 2010 and 2024, investment in tourism infrastructure consumed 32% of total capital, while energy received just 12%.
The COVID-19 pandemic, the end of preferential Venezuelan oil agreements, and years of domestic economic mismanagement had already pushed the grid to its limits. Then came the sanctions hammer.
By late 2024, blackouts were already hitting 16 to 20 hours daily. By 2026, the situation had deteriorated into something with no modern precedent for the island.
January 2026: Executive Order 14380 imposes the oil blockade.
February 3: Cuba records its lowest ever temperature – 0°C in Matanzas Province – as eastern provinces face total blackout.
February 9: Cuba announces it can no longer refuel aircraft at its airports. Air Canada suspends all flights to the island.
February 13: Fire breaks out at the Nico López oil refinery in Havana, sending a massive plume of smoke over Havana Bay and deepening the fuel crisis.
February 17: Only 44 of Havana's 106 garbage trucks remain operational. Refuse piles up on street corners across the capital.
March 4: The Antonio Guiteras Power Plant – Cuba's largest – shuts down, cutting power to millions in the western part of the country.
March 16: Cuba's entire national power grid collapses. The country goes dark.
The Antonio Guiteras failure was particularly devastating. The plant had already failed repeatedly throughout late 2024 and 2025. Each time, the sanctions maze – which deters international suppliers from selling spare parts and scares banks from processing repair payments – made restoration slower and more expensive.
"When Soviet-era thermoelectric plants break down," one analyst noted, "repairs become a sanctions maze."
The Human Cost
Statistics can obscure the human reality behind them. The numbers in Cuba's 2026 crisis are striking – but what they represent is more so.
The United Nations Human Rights Office reported that the blockade and fuel shortage have threatened Cuba's food supply and disrupted the country's water systems and hospitals. Fuel shortages have prevented the harvesting of crops and undermined efforts toward food sovereignty. The lack of fuel has also hampered UN World Food Programme relief efforts following Hurricane Melissa, which struck the island during an already desperate period.
Schools and universities have been closed. Public transport has been severely limited. The Festival del Habano – Cuba's annual cigar festival and a significant source of cultural tourism – was called off in February due to what organizers described as "the complex economic situation."
Canadian mining company Sherritt announced it would pause operations at its facility in Moa, cutting jobs in a region that could least afford to lose them.
Nicaragua, under pressure from Washington, cancelled visa-free travel for Cuban citizens in February – cutting off one of the main migration routes used by Cubans seeking to leave.
And across the island, the psychological toll of never knowing when the lights will return – or whether the generator at the local hospital will hold through the night – is immense and unmeasured.
"Nothing justifies the harm being done to boys, girls, and innocent citizens."
– Chilean President Gabriel Boric, February 2026
The World Responds
The international reaction to the 2026 Cuban crisis has been swift, largely critical of Washington, and in some cases surprising in its forcefulness.
China moved quickly. General Secretary Xi Jinping approved an aid package including $80 million in financial assistance and a donation of 60,000 tonnes of rice. Beijing's Foreign Ministry spokesperson stated that China "firmly supports Cuba in safeguarding its national sovereignty and security, and opposes foreign interference."
Russia sent a tanker carrying 100,000 tonnes of crude oil that arrived in Havana on March 30 – a shipment that could cover Cuba's energy demands for approximately 12 and a half days. The Guardian observed that the docking of the Russian vessel appeared to signal a degree of American flexibility in Cuba's ability to purchase oil abroad.
Brazil's President Luiz Inácio Lula da Silva condemned the US fuel blockade and called for humanitarian assistance. Mexico's President Claudia Sheinbaum warned of a potential humanitarian crisis, while sending two ships of humanitarian aid to Cuba despite simultaneously halting its own oil shipments under US pressure.
Chile's then-President Gabriel Boric called the blockade "criminal" and "inhumane." The UN Secretary-General António Guterres said he was "extremely concerned" about a humanitarian situation that could "worsen, or even collapse" if Cuba's oil needs were not met. UN experts described the executive order as "a serious violation of international law."
Spain, Belarus, Iran, Vietnam, the African Union, and others also expressed solidarity with Cuba.
Not all reactions were sympathetic. Argentina's President Javier Milei voiced support for the United States and condemned Cuba's government for "authoritarianism." Trinidad and Tobago's Prime Minister, while expressing concern for the humanitarian situation, stated that no CARICOM country should "entertain dictatorial governments."
Negotiations – Real or Theater?
Amid the escalation, the question of whether any genuine diplomatic pathway exists has been complicated by contradictory signals from both sides.
Trump claimed in February to be negotiating "with the highest people in Cuba." Drop Site News reported that no such high-level negotiations were actually occurring. The Miami Herald subsequently reported that US officials had been in contact with Raúl Guillermo Rodríguez Castro – a grandson of former leader Raúl Castro – who holds no senior position in the Cuban Communist Party.
Then, on March 13, Cuban First Secretary Miguel Díaz-Canel publicly confirmed on national television that his government was engaged in diplomatic talks with the United States aimed at addressing the energy blockade. The announcement came after years of frozen bilateral relations.
As a gesture of goodwill, the Cuban government announced it would release 51 political prisoners – a number that rose to over 2,000 prisoners released by April 3. The move was described as taken "in a spirit of goodwill" following engagement with the Holy See, which has been playing a quiet mediation role.
Díaz-Canel had begun the crisis in a different register – calling for preparation for "a war of the entire nation" and condemning "US imperialism." By March, the tone had shifted toward a willingness to engage, while maintaining that certain matters were "internal Cuban affairs."
Cuban opposition figures, interviewed by El País in February, offered a mixture of cautious hope and skepticism. Several warned that the Cuban government might use any diplomatic opening merely to stabilize its position before abandoning talks.
"Cuba is ready for a talk with Washington on every topic without prerequisites."
– Cuban First Secretary Miguel Díaz-Canel, February 6, 2026
The Guantánamo Question
No serious discussion of US-Cuba relations is complete without confronting the issue of Guantánamo Bay – 45 square miles of Cuban territory under US occupation since 1903 under a lease Havana has long considered illegitimate.
Cuba refuses to cash the annual $4,085 rent checks sent by Washington, viewing acceptance as implicit recognition of the deal's validity. The naval base and its notorious detention facility remain a physical symbol of foreign presence on sovereign Cuban soil – rarely debated in Washington, but central to Cuban grievances and to any meaningful pathway toward normalization.
Any serious negotiation, analysts say, must eventually reckon with Guantánamo. None of the current diplomatic signals suggest Washington is prepared to go there.
Two Causes, One Crisis
Honest analysis of Cuba's energy collapse requires acknowledging two realities simultaneously.
The Cuban government's decades of underinvestment in its electricity grid, the prioritization of tourism over infrastructure, the overreliance on Venezuelan oil without developing alternatives, and the slow adoption of renewable energy have all contributed to a fragile system that was ill-equipped to absorb external pressure.
At the same time, the United States' extraterritorial sanctions regime has amplified every vulnerability – turning manageable infrastructure problems into a humanitarian emergency. The terrorism designation alone scares international banks from processing fuel payments, deters suppliers from selling spare parts, and drives away investors in renewable energy projects that could have reduced Cuba's dependence on imported oil.
For 64 years, the stated goal of the embargo has been to pressure Cuba toward democracy. The Cuban government remains in power. The policy has not produced the desired political transformation. What it has produced is documented suffering for ordinary Cubans – the very people it claims to help.
The Path Forward
The path forward is clear, if politically difficult on all sides.
The United States would need to lift the comprehensive embargo and its extraterritorial reach, permanently remove Cuba from the State Sponsors of Terrorism list, engage seriously on Guantánamo, and allow Cubans the space to shape their own future – while pressing Havana for genuine political and economic reforms.
Cuba, for its part, would need to undertake the deeper structural reforms – in its energy sector, its economic model, and its political openness – that successive governments have resisted for decades.
Meanwhile, in a development that may offer a sliver of pragmatism over ideology, the arrival of the Russian oil tanker in late March – and Washington's apparent tolerance of it – suggests that the Trump administration may be signaling a willingness to allow some breathing room, even as it maintains maximum pressure in other dimensions.
But breathing room is not a solution. And for ordinary Cubans sitting in the dark, waiting for a refrigerator that may never start again, or a dialysis machine that may not run tomorrow, the abstract geopolitical chess match playing out in Washington and Havana offers cold comfort.
The darkness is not Cuba's alone to bear. The path to light is not solely Washington's to offer. But someone – on both sides – must choose pragmatism over ideology.
The Cuban people have waited long enough.
"The lights will keep going out in Havana, Santiago, and every corner of the island. Both sides must choose pragmatism over ideology. The Cuban people, sitting in the dark, have waited long enough."
