Cuba Energy Crisis Triggers Severe Public Health and Mental Health Toll

Severe Public Health and Mental Health Toll From Cuba Energy Crisis

A study conducted in 2025 by Cuban psychologist Yunier Broche-Pérez, director general of the Prisma Behavioral Center in Florida, along with Dr. Zoylen Fernández-Fleites, documented the heavy psychological toll of these prolonged blackouts on citizens. Broche-Pérez stated, as reported by DW, that they found very high percentages of symptoms classified in the extremely severe range: 55.4 percent for depression, 66 percent for anxiety, and 65.8 percent for stress.

The researcher emphasized that unpredictability plays a major role in these outcomes. Because citizens cannot anticipate when power will fail or how long cuts will last, they remain in a constant state of vigilance and anticipation. Experts argue that energy instability must be treated as a public health issue rather than merely a technical or economic inconvenience.

Geoeconomic Pressures and National Grid Collapses

The current energy collapse stems from an accumulation of historic infrastructure issues compounded by severe geopolitical and economic pressures. The island produces only about 40 percent of the crude oil it consumes and previously relied heavily on Venezuelan shipments, which were abruptly interrupted following the capture of Nicolás Maduro on January 3, 2026, according to El Ojo Digital. Mexico subsequently suspended its own oil shipments out of concern over United States penalties, while United States sanctions—including Executive Order 14380 signed by President Donald Trump and subsequent measures targeting state oil firm CUPET—further isolated the regime’s fuel supply, as detailed by CiberCuba and El Ojo Digital.

Cuba’s electrical infrastructure relies on seven aging Soviet-built thermal power plants constructed over four decades ago, featuring 20 total generation units afflicted by chronic investment deficits, frequent breakdowns, and maintenance challenges. On July 6, 2026, the national electrical grid collapsed at midday, leaving approximately ten million people without power in the third national blackout within a span of six months, according to El Ojo Digital.

Humanitarian Impacts and Citizen Adaptation

United Nations officials have warned of a humanitarian emergency characterized by severe shortages of food, drinking water, and medications, alongside postponed surgeries and paralyzed public transportation. State health systems face acute deterioration, and sanctions have also targeted Cuban medical missions abroad.

To cope with the lack of state-provided electricity and fuel, citizens have turned to grassroots, improvised solutions. According to CiberCuba, street transportation in Havana increasingly relies on Chinese-manufactured electric tricycles and motor scooters outfitted with rooftop solar panels, while households use lithium batteries, natural gas-powered artisanal generators, and private rooftop solar panels to keep televisions, lights, and fans running.

The Cuban government has responded by halting non-essential state labor activities, establishing community solar parks in provinces such as Guantánamo, and testing the nation’s first battery energy storage system in El Cotorro, Havana. President Miguel Díaz-Canel stated that the leadership is dedicating absolute priority to resolving the contingency, while independent consultant Emilio Romero estimated that reflotting Cuba’s electroenergetic system would require an investment of $10 billion.
