Nuclear fission is the type of nuclear power that’s been in use around the world for decades. It releases energy by splitting a heavy chemical element to form lighter ones. Fission is one thing, but some in Silicon Valley feel a different technology will be needed to plug the gap: nuclear fusion.
Unlike fission, nuclear fusion produces energy by combining two light elements to make a heavier one. But fusion energy is an unproven solution to the sustainability challenge of AI. And the enthusiasm of tech CEOs for this technology as an AI energy supply risks sidelining the potential benefits for the planet.
