The sun outputs 3.9*10^26 W. If you captured all that energy with 100% efficiency, you would need 1.3*10^36 hours or roughly 1*10^22 times the age of the universe to collect enough energy.
That’s incidentally roughly the estimated number of stars in the universe.
So if you put a dyson sphere around every star in the universe, right after the big bang (ignoring that stars didn’t form instantly after the big bang) and you ran them until today, then you’d have just about enough energy to crack one wallet with current tech.
The power consumption would be 5*10^62 Wh.
