Friedberg argues for a portfolio approach to energy, noting fusion's physics is proven by the sun's existence.
“So we have to have a portfolio of stuff. Fusion, from a first principles perspective, as you know, works because we see it working in the sky. So we know that this physics is real.”
Friedberg argues renewables cannot replace everything and a portfolio of energy sources including fusion is needed.
“Great. But they're not going to kind of replace everything. Fission has this regulatory. So we have to have a portfolio of stuff.”
