Seven months on, Democrats are still celebrating the Inflation Reduction Act, even though a crucial determinant of its success — permitting reform for energy projects — remains undone. Recent data shows just how imperative it is for them to stop dragging their feet.

What’s now called the IRA had little to do with inflation. It was a climate bill, and a big one: It provided $370 billion to improve energy efficiency, reduce emissions and smooth the path to a clean-power economy. It came on top of a 70% surge in private investment since 2017.

But the biggest impediment to the US energy transition isn’t financing: It’s building.

A decade ago, between 25% and 30% of proposed wind and solar projects moved from the drawing boards to completion. But as new projects and new funding have soared, utilities have been unable to keep up, leading to an immense backlog. A recent report by BloombergNEF found that over just six years, global clean-energy investment has gone from half the level of fossil-fuel investment to near parity, an extraordinary leap that reflects the market’s appetite for clean power. Yet America’s dysfunctional regulation is preventing many needed projects from even breaking ground.
