According to a report by the Common Wealth thinktank's Transition Security Project (TSP), Cuba could potentially eliminate its reliance on imported fossil fuels with an $8 billion investment in renewable energy. This investment could enable the country to generate 93.4% of its electricity from renewable sources, primarily solar and wind. The TSP analysis outlines that a fully renewable grid would cost approximately $19.2 billion, but even a $5 billion investment could significantly reduce fossil fuel dependence. The report highlights the urgency of this transition, especially in light of the ongoing US energy blockade, which has led to severe blackouts and energy shortages in Cuba. The analysis suggests that financing this transition should be viewed as reparative climate finance, emphasizing that it could serve as a model for other Caribbean nations facing similar challenges. Cuba has previously demonstrated its capacity for rapid transformation, as seen in its shift to agroecology after the Soviet Union's collapse in the 1990s. With over 1,000MW of solar energy already deployed, the report calls for global support to help Cuba achieve its renewable energy goals.
