Cuba's Solar Push Reflects a Grid Running on Empty
Washington's takeover of Venezuelan oil flows has pushed Havana toward solar power as the only supply it can control, with no commercial alternative in sight.
Washington's takeover of Venezuelan oil distribution in February 2026 cut Cuba's primary fuel supply, and five months on the island has not found a workable replacement. By Thursday (2026-07-17), Foreign Policy was reporting on whether Havana had sought Iranian drones, illustrating how the same US pressure that severed Cuba's oil imports has also reshaped the island's security posture.7,1
Cuba requires roughly 100,000 barrels per day to keep its electricity grid running and meet basic transport demand, according to OilPrice.com reporting from May 30, 2026. Without Venezuelan crude, the island has no established credit line or commercial channel to replace that volume. Blackouts are now routine.2
The Economist reported in May 2026 that not since the Cuban missile crisis of 1962 has Washington held such direct leverage over the island's fate. By controlling Venezuelan oil distribution, the US gained an effective veto over Cuba's energy imports at no additional policy cost, and Havana has no obvious commercial route around it.1
Cuba's official response has been to push into solar power generation. The economics are direct: panels require capital upfront but eliminate ongoing fuel purchases in foreign currency, which Cuba cannot reliably source. For a government unable to pay consistently for hydrocarbon deliveries, removing per-barrel costs entirely has an obvious appeal, whatever the infrastructure challenges.2
The drone allegations, which one analyst told Foreign Policy lack concrete public evidence, point to a parallel dynamic. The same analyst said it was "logical" for Cuba to seek defensive capabilities because Washington was "trying assiduously to overthrow their government." Cuba's energy vulnerability and its security calculus have become difficult to separate, complicating any negotiated resolution.7
Venezuela's own trajectory adds uncertainty to any medium-term projection. Atlantic Council analysis published in June 2026 estimated Venezuelan output could rise by 200,000 to 400,000 barrels per day over the next two years. But that growth requires political and investment conditions that have not materialised, and any resumed supply to Cuba would need a separate diplomatic settlement between Washington and Havana that neither side appears close to reaching.5
The broader crude environment does not help. The US-Iran ceasefire that ended nearly four months of fighting has not fully stabilised the Strait of Hormuz, and ICE Brent crude front-month closed the week at $98.70 per barrel on Friday (2026-07-25). For an economy that struggles to afford oil at lower prices, current crude prices make any commercial import strategy harder to sustain.6
The IEA's World Energy Investment report, released in May 2026, showed 64% of global energy investment flowing to clean energy. Cuba's solar ambitions are modest by comparison, but the same economics apply across sanctioned or commercially isolated economies: when oil market access is blocked or unaffordable, generation that requires no fuel imports becomes attractive regardless of ideology or grid readiness.3
US Energy Secretary Chris Wright said in June 2026 that returning to normal energy supply conditions post-Hormuz would take "many months," citing the IEA's coordinated release of 400 million barrels from strategic reserves, including 172 million from the US Strategic Petroleum Reserve, as a measure of how severe the disruption had been. Cuba drew nothing from those reserves.4
Whether Mexico, which maintains trade ties with Havana, steps in as a crude intermediary remains unclear from available reporting. The Venezuelan incremental supply, even under the Atlantic Council's optimistic scenario, is at minimum 18 to 24 months away. Cuba's solar buildout is a long-term project in an acute crisis, and the gap between those two timelines is where the blackouts live.5,2
