How much energy would it take to add to the earth's orbital velocity to push the earth into mars' orbit?

My thoughts: So, in 1-2 billion years, the sun will gradually get brighter.

Suppose a future civilization wanted to gradually move the earth farther from the sun. And for, now, please ignore that Mars is already in Mars' orbit. let's pretend there is room there.

I'm wondering what the answer looks like, in power terms, over the course of a billion years? are we talking more power than modern civilization, or if we have a billion years can we do it with just a small generator's worth of power output?

Thanks, all
