Iran War, Strait of Hormuz Closure Forces Embrace of Renewable Energy

April 26, 2026

The Strait of Hormuz has been closed for nearly two months, causing oil and gas prices to surge around the globe.

In the United States, the cost of a gallon of gas has increased by over a dollar since the strait closed, and the cost of diesel is up nearly 50 percent. Gas prices in Europe have increased by around 10 percent, and the region is facing a jet fuel shortage and concerns about the flow of liquid natural gas (LNG). Asia is being hit even harder. Roughly 20 percent of the world’s oil and LNG passes through the strait. Over 80 percent of this fuel goes to Asia. Several Asian countries, such as the Philippines, Japan, and South Korea, are now facing a real energy crisis.

All of this is obviously bad news for consumer prices in the short term, but it might benefit the climate in the long term. China produces most of the world’s solar panels, and the country’s solar exports hit a record high in March. It’s also exporting a lot more lithium batteries. Electric vehicle sales are increasing around the world.

“The fact that countries must import fossil fuels from faraway regions subjects them to uncertainties,” Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford University, tells Rolling Stone. “It is obvious that many countries want to reduce that reliance. The way to do that is to supply your own electricity and heat from clean renewable sources — primarily wind, solar, geothermal and hydroelectric. Every country has the potential to do this for themselves.”

Jacobson notes that the government of South Korea recently committed to reaching 100 gigawatts of renewable energy by 2030. The country’s energy minister has stated that the Iran war is “serving as a significant turning point” for South Korea to shift toward renewable energy and away from oil. 

“Many countries rely 100 percent on oil imports and do not produce their own,” Jacobson says. “These countries are especially vulnerable. It makes sense that they would want to transition to electrification.”
