The US Fusion Energy International Partnership Strategy “will support the timely development, demonstration, and deployment of commercial fusion energy,” the White House announced during a United Nations climate conference going down in Dubai.

Most experts don’t think commercial nuclear fusion power plants can come online in time to meet global climate goals, even under optimistic scenarios. Nevertheless, the Biden administration and Microsoft are supporting startups trying to make fusion a reality.
