A much-discussed “return to coal” by some countries in the wake of the Iran war is likely to be far more limited than thought, amounting to a global rise of no more than 1.8% in coal power output this year. The new analysis by thinktank Ember, shared exclusively with Carbon Brief, is a “worst-case” scenario and the reality could be even lower. Separate data shows that, to date, there has been no “return to coal” in 2026. While some countries, such as Japan, Pakistan and the Philippines, have responded to disrupted gas supplies with plans to increase their coal use, the new analysis shows that these actions will likely result in a “small rise” at most. In fact, the decline of coal power in some countries and the potential for global electricity demand growth to slow down could mean coal generation continues falling this year. Experts tell Carbon Brief that “the big story isn’t about a coal comeback” and any increase in coal use is “merely masking a longer-term structural decline”. Instead, they say clean-energy projects are emerging as more appealing investments during the fossil-fuel driven energy crisis. ‘Return to coal’ The conflict following the US-Israeli attacks on Iran has disrupted global gas supplies, particularly after Iran blocked the strait of Hormuz, a key chokepoint in the Persian Gulf. A fifth of the world’s liquified natural gas (LNG) is normally shipped through this region, mainly supplying Asian countries. The blockage in this supply route means there is now less gas…
