Our energy needs are ever increasing. If we ever want to get to what is currently science fiction, we'll need fusion energy, otherwise we'll eventually blanket the Earth in solar panels.

Maybe they'll be in time to provide energy to slurp carbon out of the atmosphere. Or power huge spacecraft etc etc.

Various estimates put the US’s entire energy supply as requiring enough solar panels to fill a square between 100 and 150 miles on a side. If efficiency goes up (which has upper bounds) and panels are integrated into buildings, solar being that virtually limitless supply doesn’t seem far-fetched.
