We haven't been able to utilize solar to the degree we have been able to utilize oil for all that long, and since it has, our utilization has only grown.

"Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar panels has fallen, grid-connected solar PV systems' capacity and production have doubled about every three years. Three-quarters of new generation capacity is solar"

This says nothing of, say, hydro power, which we have been using for a while

> That's like saying "in any case, the future will be better". As humans have shown, worse comes before better in history. Howabout making the present better first?

Mate I said nothing about our future or present. It's just absurd to assume our past has any bearing on how super-advanced space-faring civilizations will utilize technology.
