Cuba Turns to Solar as Venezuelan Oil Fails and US Pressure Mounts
With Venezuela's oil supply severed by US intervention and recovery seen taking many months, Havana is betting on solar to offset a chronic 100,000-barrel-a-day shortfall.
US Energy Secretary Chris Wright said on June 9 (2026-06-09) that restoring normal energy flows after months of disruption would take "many months," a timeline that falls heavily on Cuba, where the island is already in the grip of its worst power crisis in decades.7
Cuba requires roughly 100,000 barrels a day to power its grid and meet basic transportation demands, yet it is receiving far less. US intervention earlier this year severed the Venezuelan supply arrangements that had sustained the economy for years, forcing the government to accelerate solar energy deployments as a hedge against an oil supply chain it can no longer depend on.5
The shortfall traces to Washington's action in February, when the United States moved to interdict Venezuela's oil distribution. Cuba had long relied on Caracas as its primary energy supplier, and that loss left the island scrambling for alternatives in a market where its credit and political standing make conventional procurement nearly impossible.3
Mexico briefly filled part of the gap. Between May and August 2025, Mexico sent more than $3bn worth of cheap fuel to Havana, triple the volume shipped under former president López Obrador, despite Pemex's deteriorating finances.2 That arrangement has not stabilised supply, and rolling blackouts remain a daily reality across the island.
US pressure has not stopped at oil interdiction. CIA Director John Ratcliffe travelled to Havana on May 14 (2026-05-14) to deliver an ultimatum to Cuban intelligence officials, giving the government a deadline to comply with Washington's demands or face unspecified consequences.4 The posture suggests the energy squeeze is deliberate, a lever in a broader political confrontation rather than a byproduct of Venezuela policy.
Cuba's solar push is driven by necessity. Renewable generation, once built, removes the island from dependence on supply chains that sanctions or geopolitical shifts can disrupt. The government is betting that locally generated power, even if intermittent, is more reliable than a supply route vulnerable to the next US policy move.5
The crisis has prompted similar recalculations among energy importers with far more resources. India, which receives about 60% of its LNG through the Strait of Hormuz, has pivoted toward coal as high gas prices made imported fuel uneconomical. Peak power demand hit a record 257 GW, with coal-fired plants supplying upwards of 75% of generation at peak load.1 Coal imports from Russia alone jumped 95% in the first quarter of the year.1 Cuba has neither the industrial base nor domestic coal reserves to make that substitution.
Analysts have argued that Washington's leverage creates a window that could close badly. The Economist made the case in May (2026-05-17) that a negotiated settlement, however uncomfortable for the administration, would be preferable to a humanitarian collapse on America's doorstep.3 Foreign Policy wrote in early June (2026-06-04) that Washington welcomed previous adversaries including Vietnam into the global economy without demanding regime change as a precondition, a history Havana is watching closely.6
Global markets have absorbed the disruptions without outsized moves. ICE Brent crude front-month stood at $77.01 on June 23 (2026-06-23). The IEA coordinated a release of 400 million barrels from strategic stockpiles, including 172 million from the US Strategic Petroleum Reserve, to buffer the market against the worst of the supply impact.7
Cuba's scale makes it marginal to those global flows. What matters for the island is whether solar capacity can be deployed fast enough to reduce the 100,000 b/d gap before political pressure forces Washington to a harder choice. Any sign that US-Cuba negotiations have moved beyond Ratcliffe's May (2026-05-14) ultimatum, or that Havana's renewable push has drawn Chinese or European financing that changes the economics of the standoff, would shift the calculus significantly.4,5
