How much energy does the universe generate per second

[Alexander]

Counting all the things in the universe that have energy (aka, literally everything), how much energy does the universe generate per second?

And how much energy would it take to contain the equivalent of that for at least a year?

 

[Alexander]

sounds like a stupid question

Yeah this is a stupid question

Not sure how you would calculate this since only a small portion of the universe is observable currently. According to Stack Exchange, the observable universe contains about 10^70 joules of energy. r/AskPhysics says 10^50 joules per second from stars alone. I guess that makes the stars solar system level which is lower than you'd think since one star is enough to destroy multiple planets when it explodes and there are about 200 sextillion stars in the observable universe.

Technically energy cannot be created so the universe doesn't "generate" it

The universe is to big, surprise.

But I was expecting another method for this, since the thing I want to get is "absorbing the energy of a entire universe"

I'd assume that if you have all the energy of the universe, you can destroy said universe, so it probably scales to the cosmology of that universe. But this is just speculation. My reason for assuming that is because the big bang contained all the energy of the universe and also created it.

Well you could say that
