If all goes as planned, the US will eliminate all greenhouse gas emissions from its electricity sector by 2035 – an ambitious goal set by President-elect Joe Biden, relying in large part on a sharp increase in wind and solar energy generation. That plan may soon get a boost from nuclear fusion, a powerful technology that until recently had seemed far out of reach.

Researchers developing a nuclear fusion reactor that can generate more energy than it consumes have shown in a series of recentpapersthat their design…
