Cuba''s reliance on imported fossil fuels underscores an urgent need for alternative solutions like renewable energy sources—including solar power—to stabilize its electric grid
Cuba''s reliance on imported fossil fuels underscores an urgent need for alternative solutions like renewable energy sources—including solar power—to stabilize its electric grid long-term.

While small-scale, such renewable energy initiatives can reduce pressure on the energy grid and provide relief in especially vulnerable places. Due to rising temperatures and increasingly unreliable energy infrastructure, action to update Cuba’s energy grid is urgently necessary.
On top of that, Cuba’s entire grid has collapsed four times in the last six months. The problem stems from years of neglect of Cuba’s energy infrastructure, exacerbated by constrained access to foreign capital and a failure to adapt to new energy options.
Building a Cleaner, More Resilient Energy System in Cuba recommends numerous ways by which domestic policy in Cuba can prioritize working towards a more sustainable, resilient grid — especially by investing in the energy transition — and ways in which international cooperation can support these goals.
The report builds on a previous report published by EDF in 2017. That report, similar to this one, provided information on Cuba’s electric grid and recommended paths forward.
Cuba isn’t just in an energy crisis; the country’s grid sits on the verge of systemic failure. The National Electric System, most of which was built after 1959, hasn’t received the investment and maintenance it needs for 35 years—a consequence of Cuba’s complex political and economic history.
The report highlights the issue that not only is Cuba’s energy infrastructure in a precarious state of aging and disrepair, but also that its entire energy system relies heavily on external aid and imported fossil fuels.
