For some kinds of problems, a classical computer considers combinations one at a time:

ABC

ACB

BAC

BCA

CAB

CBA

While a quantum computer does it all on one step:

ABC/ACB/BAC/BCA/CAB/CBA

This is because, in some ways, quantum particles can be in more than one state at the same time!

Now imagine I had used ABCDEFGH for the example. You would be scrolling all day to get to the end of the classic computer example.

Nuclear (fission or fusion) will never scale much beyond what they currently supply. They as inefficient with regards to water usage and have strong water-requirements with regard to access and temperature. With increasing global temperature and water scarcity, these pressures against nuclear are going to keep it down.

Edit: I mean fractionally supply. They might increase moderately in absolute supply.
