The Strait of Hormuz blockade and the war in Gaza are exposing Europe’s energy and water vulnerabilities just as the continent braces for a technical recession and extreme weather swings. On Friday, the European Union’s transport commissioner, Apostolos Tzitzikostas, told reporters in Brussels that Europe faces no jet fuel shortage in the coming months despite soaring prices driven by Middle East tensions. “There are no signs that Europe will lack jet fuel,” he said, adding that the bloc’s priority is now managing cost inflation rather than supply disruption .
Yet the same geopolitical shocks are tightening their grip elsewhere. In Gaza, where food and medicine are already scarce, shortages of engine oil, spare parts and cooking gas are grinding daily life to a halt. Bakeries cannot operate, water pumps fail, and hospitals warn of imminent generator collapse as sewage floods streets and disease risks rise. The main hospital in central Gaza reported electrical failure over the weekend, deepening a humanitarian crisis that has seen the enclave’s infrastructure collapse under prolonged blockade and military control .
Across Central Asia, water scarcity is reaching a breaking point. Five countries are racing to coordinate responses after years of over-extraction and climate-driven drought left reservoirs at historic lows. Meanwhile, in southern Spain, record winter rainfall has doubled reservoir levels on the Segura river compared with last year, offering a rare respite for a basin long plagued by chronic water stress .
The energy crunch is also reshaping Europe’s climate agenda. Switzerland, heavily dependent on oil and gas imports that transit the Strait of Hormuz, has seen its vulnerability laid bare by the Iran war. A coalition of Swiss NGOs, including the Swiss Energy Foundation, has urged federal authorities to accelerate the phase-out of fossil fuels, warning that centralised energy systems are dangerously exposed to geopolitical shocks .
Against this backdrop, the United Nations is pushing for accelerated renewable deployment ahead of COP31 in Antalya this November. The UN resident coordinator in Türkiye warned that the Strait of Hormuz blockade has exposed global energy vulnerabilities and reinforced the case for a rapid shift to renewables .
From Gaza’s collapsing infrastructure to Europe’s strained grids and Central Asia’s shrinking rivers, the converging crises of fuel, climate and water are redefining the continent’s immediate priorities—and exposing the fragility of systems that once seemed resilient.
