What began as escalating tensions in the Strait of Hormuz in mid-March 2026 has evolved into a full-scale war between the United States, Israel, and Iran, with the strait blockaded since early March. This vital chokepoint for 20% of global oil and natural gas shipments has ignited the most severe energy crisis in modern history, causing critical fuel shortages in 25 countries.
The crisis traces back to March 22, 2026, when tensions surged: Iran threatened to restrict passage through the Strait of Hormuz—handling over 20% of the world's crude oil and LNG—for vessels linked to adversaries. U.S. President Donald Trump issued a 48-hour ultimatum to keep the strait open, warning of strikes on Iranian power plants. Retaliatory threats and attacks on commercial shipping followed, escalating into open war and a complete blockade by early March's end. Major producers like Iran, Iraq, Kuwait, Saudi Arabia, and Qatar halted shipments, with Qatar's LNG facilities damaged by Iranian drone strikes.
The fallout is worldwide. Asian powerhouses Japan, South Korea, and Singapore, heavily dependent on the strait's LNG, have reactivated coal plants—South Korea lifted emissions caps, Italy extended coal plant operations. Governments worldwide enacted conservation: speed limits cut, remote work mandated, thermostats raised, fuel taxes waived. Airlines slashed flights as jet fuel prices soared, pushing some U.S. carriers toward bankruptcy. Electric vehicle sales spiked—over 50% in France and Germany, nearly 200% in Brazil—in the war's first month.
Yet, the crisis accelerates the shift to alternatives. UN adviser Selwin C. Hart declared at a Colombia conference, “We now have a viable alternative. Renewables have changed the equation.” Solar boomed: Chinese panel and battery exports to India, Africa (up 176%), and Europe surged in March. Vietnam pivoted from a 4.8-GW LNG project to wind, solar, and batteries. South Korea fast-tracked a 100-GW renewables plan by 2030. Nuclear gained momentum too—Taiwan plans to restart Maanshan, Japan signed deals with the U.S. and Indonesia, Belgium halted all decommissioning, per Prime Minister Bart De Wever: “All decommissioning activities are being halted with immediate effect.” Ember analyst Daan Walter cautioned, “It’s hard to say which direction things will go,” amid coal's temporary resurgence.
