A senior CIA official has made an unannounced visit to Havana, according to diplomatic sources, at a time when Cuba is experiencing a catastrophic failure of its electrical grid. The United Kingdom, which maintains significant economic and security interests in the Caribbean, has been monitoring the situation closely. The implications for regional stability and energy security are profound.
Cuba’s energy infrastructure, already fragile due to decades of underinvestment and US sanctions, collapsed entirely last week. Rolling blackouts now affect 18 of the island’s 15 provinces, with hospitals operating on backup generators that are running low on fuel. The government has declared a state of emergency. The blackouts are not merely an inconvenience: they threaten water purification, food storage, and the operation of critical industries.
This is where the security dimension becomes unignorable. An energy-collapsed Cuba creates a vacuum that could be exploited by illicit actors. The US, wary of increased migration flows and potential destabilisation, has a direct interest in preventing a humanitarian crisis that could spill across the Florida Straits. The UK, while geographically distant, has a sovereign base area in Bermuda and maintains close ties with Caribbean nations such as Jamaica and the Bahamas. Any regional instability affects British interests, including financial services and tourism.
The CIA visit is likely focused on assessing the risk of a total state failure and the security of Russian or Chinese assets on the island. Cuba has long been a client of Russian energy technology, and recent reports suggest that Chinese firms are involved in repairing damaged power plants. This geopolitical entanglement complicates any international response. The UK’s Foreign Office has stated it is “monitoring the energy situation in Cuba with concern” and is coordinating with US and Canadian partners.
From a scientific perspective, Cuba’s predicament illustrates a broader vulnerability. Tropical island nations are disproportionately reliant on imported fossil fuels, making them exceptionally vulnerable to price shocks and supply disruptions. Cuba, which has some of the Caribbean’s most underutilised solar and wind potential, has failed to diversify. The collapse is a case study in the physical reality of energy insecurity: when the lights go out, everything fails.
The security implications for the wider Caribbean are clear. A destabilised Cuba could increase migration pressure on neighbouring states, from the Bahamas to the Cayman Islands. There are also concerns about increased drug trafficking; a country without reliable electricity has weakened border control and surveillance capabilities. The UK’s Joint Maritime Security Centre has already noted a rise in suspicious vessel activity in the Caribbean corridor.
What happens next is a matter of intense diplomatic negotiation. The US has signalled a willingness to temporarily lift some sanctions to allow fuel shipments, but this requires trust on both sides. The UK is advocating for a coordinated regional response, potentially through the Caribbean Community. The goal is to prevent a isolated energy crisis from becoming a full-blown security catastrophe. As I have said before: energy transition is not a policy preference; it is a survival requirement. The biosphere does not care about geopolitics. It cares about physics. And the physics of a grid with zero fuel is immediate, brutal, and non-negotiable.
