A potential escalation with Iran could upend global energy markets in ways that push nations toward an unlikely fuel: coal.
Conflict with Iran has historically triggered oil price spikes. If crude supplies tighten significantly, countries facing energy shortages may turn to coal as a more available alternative, reversing years of momentum toward cleaner energy sources.
The dynamic echoes the 1970s energy crisis, when President Jimmy Carter confronted Americans with uncomfortable truths about resource scarcity. In 1977, as oil prices climbed and supplies grew precarious, Carter delivered his famous "fireside chat," urging the nation to brace for what he called a permanent energy shortage. He asked Americans to lower thermostats to 65 degrees during the day and 55 degrees at night, a suggestion that proved deeply unpopular during a harsh winter.
Today's geopolitical uncertainty could recreate similar pressures. Nations heavily dependent on oil imports might face acute shortages if Iran tensions escalate into disruptions of shipping lanes or production. Rather than endure immediate energy rationing or soaring prices, governments may accelerate coal extraction and consumption as a stopgap measure.
The paradox is stark: a military conflict aimed at containing one regional threat could inadvertently strengthen reliance on the dirtiest fossil fuel, undermining climate commitments many countries have made. Coal plants take time to build, but existing facilities can ramp up operations quickly, making coal the path of least resistance during an energy crisis.
The calculus facing policymakers is becoming clearer. Short-term energy security and long-term climate goals are increasingly at odds, with geopolitical instability tilting the scales toward immediate solutions, regardless of environmental costs.
