Nuclear fusion is probably the key many of the world's problems, from climate change onwards.
The UK is about trial a new design of fusion reactor.

Depends on how expensive a fusion reactor is to operate. Renewable energy is already less expensive than fossil fuels, and batteries can supply power in off hours. Until it is done, I'm skeptical; they have been working on fusion for a long time, with almost no power produced so far. It would, however, be a great source of energy.

Batteries, of themselves, are polluting and limited in capacity.
Fusion energy, if it can be made viable, is "on demand". I live in hope.
@Petter You are right fusion about less polluting. Battery recycling has improved significantly, so battery pollution will not be nearly as bad as oil. One way or another, we will have green energy; everything is limited, but battery materials are sufficient to continue power when neither wind nor solar produce energy. For example, one proposal is to convert school busses to electric and attach them to the grid when parked to charge or discharge. When discharging they provide power on demand.
Tesla used about 35 GWh of batteries this year, and plan to increase production to 100 GWh next year, and have orders from utility companies for all they can produce for several years. IDK the capacity limit, but it is huge.
