Cuba's Energy Crisis: The Push for Renewables Amid Sanctions
2/19/2026, 2:44:39 AM
The Current Energy Landscape in Cuba
Cuba is grappling with a severe energy crisis exacerbated by U.S. sanctions, particularly those imposed during Donald Trump's presidency. The sanctions have significantly restricted oil imports, which are crucial for electricity generation, leading to widespread blackouts that can last up to 24 hours. The situation has been described as a humanitarian disaster, with the Cuban government declaring a national emergency reminiscent of the 1990s "special period" following the Soviet Union's collapse. Approximately 80% of Cuba's electricity relies on petroleum derivatives, and the lack of fuel has severely impacted daily life, affecting hospitals, schools, and transportation.
The Role of Renewable Energy
In response to the energy crisis, Cuba is accelerating its transition to renewable energy sources, aiming to increase the share of renewables to 26% of its total energy supply by 2035. The government has announced plans to construct solar parks and wind farms, with significant investment and technical support from China. By October 2025, Cuba had completed 35 solar parks with a total capacity of 750MW, contributing to a notable increase in renewable energy generation. However, the country still faces challenges, including outdated infrastructure and a lack of battery-storage capacity, which limits the effectiveness of solar energy during peak demand hours.
Investment and International Support
Cuba's ambitious energy transition is projected to require investments of $8 billion to $10 billion over the next decade. While China has emerged as a key partner, providing solar technology and funding, experts caution that Cuba's economic constraints may hinder the necessary scale of investment. The Cuban government has set a target of installing 92 solar parks with a total capacity of 2GW by 2028, but the lack of financial resources remains a significant barrier.
Criticism and Opposition
Critics argue that the Cuban government's energy transition strategy underestimates the investment needed to modernize the country's aging power infrastructure. Jorge Piñon, an expert at the University of Texas’s Energy Institute, highlights that Cuba's transmission system is inefficient, with about 16% of generated electricity lost during transmission. Additionally, the reliance on renewable energy alone is insufficient; experts suggest that upgrading fossil fuel-based thermoelectric plants is also necessary for a balanced energy strategy.
Official Statements and Responses
Cuban officials have emphasized the urgency of transitioning to renewable energy as a means to alleviate the ongoing power shortages. Deputy Prime Minister Óscar Pérez-Oliva Fraga stated that the government prioritizes the construction of solar parks to address the crisis. Meanwhile, Cuban Ambassador to Brazil Adolfo Curbelo Castellanos condemned the U.S. sanctions as "genocidal," arguing that they deprive the Cuban people of essential resources and threaten the nation's sovereignty.
Conflicting Reports and Gaps
While the Cuban government reports significant advancements in renewable energy, discrepancies exist regarding the actual impact of these initiatives on the energy crisis. Some sources indicate that solar energy now accounts for about 10% of national electricity generation, while others suggest that the infrastructure challenges and economic limitations may prevent a substantial shift away from oil dependency.
Conclusion: The Path Forward
Cuba's energy crisis highlights the complex interplay between international sanctions and domestic energy policy. As the government pushes for renewable energy development, the challenges of financing, infrastructure modernization, and technical expertise remain critical hurdles. The future of Cuba's energy landscape will depend on balancing these factors while navigating the ongoing geopolitical tensions surrounding its oil supply.
