The Debrief: Power and energy

technologyreview.com Mat Honan 2026-03-29 05:00:00

Yet in many ways right now the US seems to be forgetting those lessons. It is moving backward in terms of its clean-energy strategy, especially when it comes to powering the grid, in ways that will affect the nation for decades to come—even as China and others are surging forward. And that retreat is taking place just as electricity demand and usage are growing again after being flat for nearly two decades. That growth, according to the US Energy Information Administration, is “coming from the

Managing time when time doesn't exist

The Ultimate Productivity Paradox Imagine explaining to your boss why you’re late for a meeting because time doesn’t actually exist. Not in the philosophical “time is a social construct” sense that gets you invited to fewer dinner parties, but in the rigorous scientific sense where quantum gravity’s most fundamental equations contain absolutely no time variable whatsoever. You’d be attempting to justify tardiness using cutting-edge physics to someone whose greatest temporal insight is schedulin

It is to this principle that I believe I owe everything I’m truly good at.
