Cuba's Energy Crisis: The Push for Renewables Amid U.S. Sanctions
2/18/2026, 7:46:21 PM
The Current Energy Landscape in Cuba
Cuba is grappling with a severe energy crisis exacerbated by U.S. sanctions, particularly under the Trump administration, which intensified the oil blockade against the island. This blockade has crippled Cuba's ability to import oil, leading to widespread blackouts and a humanitarian crisis. The country, which heavily relies on oil for electricity generation—approximately 80% as of 2023—faces prolonged power outages, with some regions experiencing blackouts lasting up to 24 hours.
Historical Context and Environmental Vulnerability
Cuba's vulnerability to extreme weather events, such as hurricanes, has been documented by the Intergovernmental Panel on Climate Change (IPCC). The island's environmental degradation, particularly from its historical sugar industry, has further diminished its resilience to climate impacts. The government has recognized the urgent need for an energy transition, committing to increase renewable energy sources to 26% of its total energy supply by 2035.
Government Initiatives and Renewable Energy Projects
In response to the energy crisis, the Cuban government has initiated several renewable energy projects, primarily supported by Chinese investment. By October 2025, Cuba had completed 35 solar parks with a total capacity of 750MW, contributing to a significant increase in renewable energy generation. The government aims to install 92 solar parks with a combined capacity of 2GW by 2028. However, experts warn that the transition requires investments of $8 billion to $10 billion, which Cuba currently lacks.
Challenges in the Energy Transition
Despite the rapid expansion of solar energy, Cuba's energy infrastructure remains outdated. The transmission system is inefficient, with about 16% of generated electricity lost during distribution. Additionally, the lack of battery storage capacity poses a significant challenge, as solar energy production is limited to daylight hours, while peak demand occurs in the evening. Experts argue that while renewables are essential, Cuba must also upgrade its fossil fuel-based thermoelectric plants to ensure a stable energy supply.
Criticism and Opposition
Cuban officials have condemned the U.S. sanctions as a "genocidal" policy that exacerbates the suffering of the Cuban people. President Miguel Diaz-Canel has criticized the blockade for crippling the economy and limiting access to essential resources. The Cuban ambassador to Brazil has described the situation as a humanitarian crisis, asserting that the sanctions aim to deprive the Cuban people of their means of subsistence.
Verbatim Quotes
- “Without energy, everything is compromised. What they did was condemn the Cuban people to extermination. A country like Cuba, which needs oil to generate electricity, simply cannot import it in the exercise of its sovereign right. The sovereignty of the rest of the world was also violated by the US, not just Cuba's,” — Adolfo Curbelo Castellanos, Cuban Ambassador to Brazil
- “The energy transition outlined by the government would require investments of around $8bn to $10bn over the next decade,” — Ricardo Torres, Economist
What's Next for Cuba's Energy Future?
As Cuba continues to navigate its energy crisis, the government remains focused on expanding renewable energy sources while addressing the immediate challenges posed by its aging infrastructure. The hope is that increased investment and international cooperation, particularly with China, will facilitate a more sustainable energy future for the island. However, the ongoing U.S. sanctions pose a significant barrier to achieving these goals.
