By 2030? Lol. Lmao, even. 2050 if we're lucky--we're still not even close to developing a reactor that can produce meaningful amounts of power for a sustained period. It'll take decades more to get to that point, and once all the technical limitations have been crossed and we figure out how to get enough tritium, the actual hard work begins of getting it online and integrated with our current system. Fusion is distant future technology.
