Fusion

Elon Musk on Fusion Energy

Fusion is the “energy forever” solution. You know all energy in the universe originates with fusion. We get our energy from the sun, so that’s indirect reliance on fusion.

Do I think it will be solved this century? It may not be possible – or at least, not on a commercially viable scale. It’s a very, very difficult technical problem, one of the most difficult technical problems that humanity will ever try to solve. But if we solve it, we will have “energy forever.”
