They shut down nuclear plants and returned to coal: the lesson learned

Published on May 09, 2026 | Translated from Spanish

After the closure of several nuclear power plants due to political or social pressure, countries like Germany and Japan faced a predictable problem: electricity generation was insufficient. The emergency solution was to reopen coal plants, the most polluting source. A move that many describe as a step backward in the climate fight.

The technical dilemma: intermittent renewables vs. stable baseload ⚡

The energy transition requires baseload power sources, something nuclear provides with high availability. By retiring these plants without massive energy storage (grid-scale batteries), the grid becomes dependent on gas or coal to cover peaks. Battery technology is advancing, but it still does not replace the constant output of a 1 GW nuclear reactor running 24/7.

The master plan: shut down clean to open dirty 😅

The strategy was brilliant: shut down nuclear plants that emitted no CO2, only to burn coal that does. It's like leaving the electric car at home to drive a diesel to work because the gas station across the street has better coffee. Expert-level energy efficiency: pollute more to solve a problem that didn't exist.
