The following article, originally published in Microgrid Media (an independent news platform dedicated to covering the global shift toward renewable energy) details how, over the last 12 months alone, Cuba has managed to increase its solar-generated electricity from 5.8 percent to over 20 percent of total generation. “The Caribbean nation connected 49 new solar parks to its grid between early 2025 and early 2026, adding more than 1,000 megawatts of capacity with equipment and financing from China. The expansion represents one of the fastest renewable energy transitions ever achieved by a developing country.”
The author notes that China’s support has been indispensable to these efforts. “The rapid expansion would have been impossible without sustained support from Beijing. China committed to building 92 solar parks by 2028 with combined capacity of approximately 2,000 megawatts, nearly matching Cuba’s entire current fossil fuel generation capacity. Beyond large solar farms, China donated approximately 70 tons of power generator parts and committed to installing 10,000 photovoltaic systems for isolated homes and critical facilities including maternity wards and clinics.”
In the face of a cruel, criminal and escalating US energy blockade, Cuba’s rapid progress in solar power represents a substantial boost for defending the country’s sovereignty and its socialist development path. The article observes: “If Cuba sustains installation pace, achieves adequate battery storage, and maintains Chinese support through 2028, it could reach energy independence that renders oil blockades economically irrelevant.”
We have previously covered China’s support helping Cuba advance towards energy sovereignty and sustainability, as well as China’s recent emergency aid to the island.
Cuba has transformed its electricity system in just 12 months, increasing solar power from 5.8% to over 20% of total generation as the country races to escape dependence on oil imports now blocked by US sanctions.

The dramatic shift comes as Cuba faces what officials call an “energy siege.” President Donald Trump signed an executive order in early 2026 threatening tariffs against any country providing oil to the island, cutting fuel imports by approximately 90 percent and triggering blackouts lasting up to 20 hours per day in some regions.
