The disruption in the Strait of Hormuz has cut access to one-fifth of the world’s oil and gas supply, leaving many countries scrambling for alternatives.

Policymakers say immediate energy needs supplant environmental concerns.

Others are hoping to turn to renewables. Solar power is now the cheapest form of electricity in many parts of the world. But renewables, especially wind, have faced hostility from the Trump administration.
