The Director of the CIA has made an unannounced visit to Havana as Cuba endures its most severe energy crisis in decades, with rolling blackouts now exceeding 18 hours per day in several provinces. The visit, confirmed by both US and Cuban sources on condition of anonymity, comes as the island's ageing Soviet-era power plants fail at an accelerating rate. The British consulate has placed its emergency response team on standby, advising UK nationals to stock supplies and monitor local alerts.
This is not a diplomatic gesture. It is a real-time acknowledgment that the collapse of a nation's energy infrastructure triggers cascade failures in water, healthcare, and communications. Cuba's grid operates on less than 40 per cent of its required capacity.
The physics of this is simple: when baseload generation drops below critical thresholds, frequency instability forces protective shutdowns. The result is a blackout that is not hours but weeks long in some districts. For the climate scientist, this is a case study in what happens when adaptation fails.
Cuba has invested heavily in solar and wind, but storage lags. The lesson for the wider Caribbean and indeed the global south is that energy transition must be accelerated before, not after, the existing system disintegrates. The CIA chief's presence suggests that the US government now sees this as a security issue, not merely a humanitarian one.
The optics are uncomfortable: a nation propped up by Chinese and Russian fuel imports now unable to keep the lights on. Meanwhile, British consulate staff are distributing satellite phones and water purification tablets. The calm urgency in their communications is palpable.
As the biosphere sends its warnings, we continue to treat energy as a political variable rather than a physical necessity. It is not. It is the difference between a functioning society and a humanitarian crisis.
The data are clear. The question is whether we will act before the next domino falls.
