Cuba could potentially dismantle the impact of the U.S. Energy blockade through a strategic $8 billion investment in renewables, according to a new analysis from the Common Wealth thinktank. The report suggests that such a transition would not only secure the island’s power supply but could establish the socialist republic as a blueprint for green energy independence across the Caribbean.
The proposal arrives during a period of acute crisis for Cuba’s infrastructure. Since January, the island has received only a single shipment of oil, sourced from Russia, following a U.S. Executive order that threatened trade tariffs on any nation selling fuel to the government in Havana. The resulting fuel scarcity led to a systemic collapse of the national electric grid by March, leaving 10 million people to face repeated, nationwide blackouts.
The humanitarian toll has been severe, with reports of power failures in hospital intensive care units and the total cessation of transport and industrial activity. This volatility has been underscored by the rhetoric of the U.S. Administration, with Donald Trump stating, “I do believe I’ll be … having the honour of taking Cuba.”
The analysis, conducted by the Transition Security Project (TSP), argues that the current reliance on imported fossil fuels is a primary vulnerability that the U.S. Leverages to maintain regional influence. By shifting to a decentralized, renewable-based grid, Cuba could effectively neutralize this leverage although lowering the long-term cost of electricity.
The Financial Path to Energy Independence
The TSP analysis modeled four distinct investment scenarios to determine how much capital is required to break the cycle of fossil fuel dependence. The findings indicate that while a total transformation of the grid would be the most expensive option, significant relief could be achieved with much lower initial spends.
According to the report, an investment of $8 billion would be sufficient to cover 93.4% of Cuba’s electricity generation needs. For those seeking a more comprehensive solution, a total investment of $19.2 billion could make Cuba the first country in the Caribbean to operate on a grid powered entirely by renewables. Even a more modest rollout of $5 billion would reduce the country’s reliance on imported fossil fuels to just 20% of its total generation.
| Investment Amount | Impact on Fossil Fuel Reliance | Estimated Cost per kWh |
|---|---|---|
| $1 Billion | Partial reduction | 12.1¢ |
| $5 Billion | Reduced to 20% | 7.3¢ |
| $8 Billion | Reduced to 6.6% (93.4% renewable) | 6.5¢ |
| $19.2 Billion | 100% Renewable | 9.9¢ |
The report notes that electricity would be cheaper in every renewable scenario compared to the “business as usual” baseline, where costs currently sit at 14.3¢ per kWh. The most ambitious plan relies heavily on solar power—accounting for 75% of generation—with wind providing 20%, and the remainder coming from bioenergy and hydropower.
Strategic Implications and Regional Modeling
Kevin Cashman, a researcher with the TSP and author of the analysis, frames the issue not just as a technical transition but as a geopolitical necessity. He argues that the U.S. “energy dominance strategy” is designed to entrench dependence on fossil fuels to strengthen American power in the hemisphere.
“For countries like Cuba – with enormous renewable potential, but suffering blackouts and widespread suffering under a cruel and illegal US-imposed energy blockade – a transition to green electricity would reduce US leverage and provide a shining example to the world,” Cashman stated.
The transition would require a massive shift in societal organization, but the report points to Cuba’s history of rapid adaptation. Following the collapse of the Soviet Union in the 1990s, the island underwent a forced but successful transition toward agroecology and agricultural self-sufficiency. The TSP suggests this precedent proves Cuba’s capacity for large-scale systemic change under external pressure.
Current efforts are already underway. Over the past year, the Cuban government has brought more than 1,000MW of solar capacity online, supported by financing and technical assistance from China. This existing infrastructure serves as a proof-of-concept for the larger scale-up proposed by the thinktank.
The Question of Funding and Reparations
The central challenge remains the source of the multi-billion dollar investment. The TSP analysis argues that the funding should not be viewed as a traditional loan or a gift, but as “reparative climate finance.” This framework suggests that wealthier nations, whose historical emissions have contributed to the climate vulnerability of island nations, have a financial obligation to fund the transition.
The report contends that such an investment would be economically viable, as the savings generated from cheaper, domestically produced renewable energy would allow Cuba to pay back the investments over time. The successful implementation of such a grid would serve as a global case study in maintaining energy security under extreme external constraints.
This proposal has gained traction among some U.S. Policymakers. House Democrats have recently called for an finish to the “cruel” energy blockade, citing the humanitarian crisis and the potential for a green transition to stabilize the region.
The next critical phase for Cuba’s energy sector involves the continued integration of solar projects and the potential for new international financing agreements. As the island continues to navigate the constraints of the U.S. Blockade, the feasibility of the TSP’s $8 billion roadmap will likely depend on whether the international community views the transition as a matter of climate justice or geopolitical strategy.
