The 1000 miles road starts with a first step, and it's not like we can't pursue several approaches at once. People like grandparent poster suggest us drop everything and concentrate on the idea he likes best. That is a very bad and harmful idea.
No one is saying we shouldn't invest in exploring fusion. But we shouldn't sit on our hands on the interim. We need to invest heavily in the best alternative resource available right now till such time as fusion is a viable alternative to solar.
Keep in mind horses and cars co-existed as mainstream transportation choices right up till the end of world war 2.

Actually, jhallenworld's comment was saying exactly this: "We should put more resources into storage now, fusion can wait".
That's what prompted my response about horses in the first place. Analogy is apt, because first engines were wildly inefficient compared to horses, yet, if people back then would never pursue them, we would never have eventual progress. So no, while we should invest in storage, fusion CAN NOT wait.
