Cuba Jumps From 6% to 20% Solar in One Year With China's Help

Cuba shattered its solar power record on back-to-back days in February 2026, first generating 800MW in one afternoon, then topping it with 900MW the next day. The achievement prompted a celebratory announcement from the country's Ministry of Energy and Mines and showed what's possible when nations commit to clean energy transformation.

The numbers tell a remarkable story of rapid change. In January 2025, solar power made up just 5.8% of Cuba's total energy generation. By January 2026, that share had jumped to 20%.

For decades, Cuba relied heavily on expensive imported fossil fuels, partly due to prolonged U.S. sanctions that limited energy options. The country needed a new path forward, and it found a willing partner in China.

China is helping Cuba build 92 solar parks by 2028, with dozens already operational across the island. But the partnership goes beyond just installing panels during sunny days.

The Ripple Effect

The real game changer is solving Cuba's energy timing problem. Peak electricity demand hits between 7 and 8 p.m., well after sunset. China is exporting battery storage systems to Cuba so the daytime solar energy can power homes when families actually need it most.

More than 10,000 standalone solar kits have already been installed in homes and institutions not yet connected to the national grid. These systems are powerful enough to run refrigerators, fans, and televisions, bringing electricity to thousands of people for the first time.

The impact reaches beyond individual households. A family that can now keep medicine cold, study after dark, or stay connected to the outside world experiences life-changing improvements in health, education, and opportunity.

China's support extends to wind energy too. Chinese firms have built wind farms across Cuba that have already prevented several tons of carbon dioxide from entering the atmosphere.

Cuba's transformation shows that smaller nations can make big strides in renewable energy when they have the right partnerships and commit to change. What seemed impossible just two years ago is now Cuba's new reality.
