Nuclear fusion has the potential to be a major game-changer in the energy sector, as it could eventually provide a much cleaner and more sustainable form of energy than traditional fossil fuels.

However, it's still in the early stages of development and there are a lot of challenges that need to be overcome before it can be commercialized.

Renewables, on the other hand, will continue to play an important role in the energy sector even if nuclear fusion becomes a reality, as they are currently much cheaper and more readily available than fusion power.

But if fusion can be harnessed on a large scale, it could eventually completely replace traditional fossil fuels and usher in a new era of clean energy.
