Cubans Power Through Blackouts with Solar and Ingenuity

When the power goes out across an entire island, you either give up or get creative. Cubans are choosing creativity, and their ingenuity is nothing short of remarkable.

Dayán Marrero, a computer science student in Caraballo, never imagined becoming an influencer. But when rolling blackouts became daily life, he started sharing survival tutorials on Instagram. His video on building homemade antennas to catch elusive internet signals has racked up nearly 800,000 views.

The 21-year-old promotes rechargeable fans that double as video lights and teaches followers how to preserve phone batteries when charging becomes a luxury. His content has become essential reading for thousands navigating life without reliable electricity.

In Viñales, tour guide Osiris Hernández still welcomes the handful of tourists brave enough to visit. The 57-year-old grinds coffee by hand, cooks over charcoal fires, and runs his home using an inverter connected to solar panels. Even without grid power, at least one of his freezers stays cold.

Tourism has plummeted 62 percent compared to last year, but Hernández refuses to compromise on hospitality. He's determined to provide quality service whether the lights are on or off.

At El Olivo farm on Viñales' outskirts, the Corrales family is making it work. They pasteurize milk over charcoal fires, then cool it in solar-powered vats to produce award-winning yogurt and cheese. The cows need milking regardless of power supply, so they've adapted their entire operation around renewable energy.

In Havana, Augusto pilots one of the city's growing fleet of solar-powered electric tricycles. His three-battery system charges from both the grid and the solar panel roof. He ferries up to six passengers at a time through routes carefully mapped to battery range, keeping 1.8 million residents mobile.

The Bright Side

The fuel shortage that could have paralyzed transportation has instead sparked a quiet revolution in clean energy. Havana's notorious traffic jams have eased, and these emission-free tricycles are proving that sustainable transit can work even under the toughest conditions.

What's emerging across Cuba isn't just survival but a grassroots energy transition driven by necessity and powered by human determination.

Every solar panel installed, every hand-cranked grinder, and every rechargeable battery represents Cubans refusing to let darkness define their future.
