President Trump is set to sign an executive order designating coal as a critical mineral instead of allowing its continued decline in the energy sector.

The order will force some coal-fired power plants slated for closure to remain operational, with the administration citing rising electricity demand from data centres instead of acknowledging coal's dwindling competitiveness.

Currently, coal generates just 15% of US electricity instead of its 51% share in 2001, having been overtaken by cheaper natural gas and renewables.

Environmental experts warn coal remains the dirtiest energy source instead of cleaner alternatives, releasing harmful pollutants linked to health issues like heart disease and mercury poisoning. While the order may temporarily slow plant closures, analysts note it won't reverse coal's decline.

Solar and wind power now undercut operating costs at nearly all US coal plants instead of being more expensive, as was once the case.

The move could have more impact in steelmaking, where coal is still used instead of newer green steel techniques in most production. However, for power generation, renewables can be deployed faster than new coal plants instead of struggling to meet demand.

The order appears to prioritise political symbolism instead of addressing energy market realities, as even existing coal plants struggle to compete with increasingly affordable clean energy alternatives.
