Cuba is currently experiencing one of its worst energy crises, characterized by severe fuel shortages and extensive blackouts, with some neighborhoods lacking electricity for up to 22 hours a day. Cuban Energy and Mines Minister Vicente de la O Levy has confirmed that the country has run out of diesel and fuel oil, leading to a critical state of the national grid. To combat this crisis, China is stepping in as a key partner, significantly expanding solar energy infrastructure across the island. Chinese exports of solar panels to Cuba are projected to surge from $3 million in 2023 to $117 million by 2025. Additionally, Cuba and China are collaborating on a major initiative to construct 92 solar farms by 2028, expected to generate around 2 gigawatts of electricity, enough to power nearly 1.5 million households. Despite these advancements, experts warn that Cuba's aging power grid and economic challenges may hinder the effectiveness of renewable energy solutions. The government aims to boost the share of renewables in its energy mix from 10% today to at least 24% by 2030.
