Are there any theoretical space fuels that are completely renewable? I don't want to be stuck on this rock cause early colonizers used up all the good stuff

What is "renewable" to you?
something we won't run out of even if 8 billion people decided to earthxit
The Moon has tritium on tritium on tritium.
well, there's solar power and wind power
how do you exit orbit with solar power?
Saving up for a while.
Saving up for a while and then what? how would you propel yourself with that energy?
Nothing is completely renewable, and never will be. There will always be some lost energy we can not capture.
But we can get pretty damn efficient. I don't think there is a limit to how effectively we can use the resources we can produce.
Hydrogen and oxygen have been used as rocket fuels and are completely renewable.
Electrolyzing water

Why not both*

...has nothing to do with "renewable".
Solar wind.
Lrn2solar-wind fgt pls

Naturally occurring gases like oxygen and hydrogen and methane.
That's what SpaceX is using to get away from kerosene which is expendable
Solar sails. Surprised no one has said it so far.
Space travel is pointless.
Jizz. Just make sure to bring lots of fap material. And to those who say ya but you need food and water to make jizz, well if you're out of food and water you're fucked anyway right?? And you might need to wait to save up enough, but as someone ponted out that's a problem for solar too.
Trust me, it works. Currently working on jizz powered moped, hoping to get DARPA funding for jizz powered rover.
those things work by heating the air inside the cone, you still need something to burn for it to work in space
that makes water the non-renewable resource
for everyone saying solar wind

it only works WELL until you reach the termination shock, about 80 AU from the sun, and it no longer works when you're outside the solar system. It's not necessarily a bad idea, but you will still need some kind of combustible fuel for the space between stars
