Within 20-40 years (by about 2065), fusion and solar will be the world's two primary energy sources.

“And fusion I think is definitely doable, it seems, if we have the right design of reactor and we can control the plasma and fast enough and so on, and I think both of those things will actually get solved. So we'll probably have at least those are probably the two primary sources of renewable, clean, almost free or perhaps free energy.”
