First study to look at long-term effect of insulation finds fall in gas consumption per household was small, with all energy savings disappearing by the fourth

Look for significant progress in 2023 in two key areas, writes a veteran of international climate policy.

Unique PSFC-designed spectrometer provides crucial data about the implosion that yielded an historic fusion energy gain.

A US national lab has proved we can the fusion process can be used to produce energy, but it’s just the first step in a very long process.

The US government regulates many industries, but social media companies don’t neatly fit existing regulatory templates. Systems that deliver energy may be the closest analog.

Huge challenges remain before working fusion reactors are possible.

The promise of abundant, clean energy powered by nuclear fusion is one big step closer thanks to a new experiment. The results are a historic scientific milestone, but energy production remains a ways off.

Harvard scientist Adam Cohen breaks down breakthrough that might prove major turning point in clean energy efforts — but not any time soon.
