When it comes to building a sustainable economy that doesn't rely on fossil fuels, California is out in front. One firm that is crucial in this effort is FEAM due to the mining of its boron resource, which is needed in the development of renewable energy technologies.

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.
