The EPA power-plant rollback meets the demand surge

Removing the climate ceiling on a country's largest stationary emitter is one decision. Plugging in a generation's worth of new electric load in the same window is another. Doing both at once, in a country that still leads the world in cumulative emissions, is the choice the United States is making.

Three drivers are pushing US electricity use up at the same moment the federal greenhouse-gas cap on power plants is being removed: AI data centers, EVs, and a reshored manufacturing base. Whatever share of the next marginal megawatt is fossil, then, is the share the rollback is now choosing, because the ceiling was the only constraint that would have forced substitution away from it.

The mechanism is portable. Every jurisdiction that wants to host the new electric load faces the same sequencing: whether the cap on the incumbent source is in force while the new demand is being met, or after. Default to "after" and the next increment goes to the incumbent. Default to "before" and the new demand has to clear the bar the existing fleet failed.

Browning's line carries the human ledger for that arithmetic. The household version of the same calculation the policy just declined to make.
