Off the top of my head, you could get some solar power with a massive array. Itโs possible to generate oxygen from the Martian atmosphere, as NASA recently proved.
I would think any permanent structure on Mars is going to be more like the ISS except underground. So, basically everything will have to be resupplied from Eart. There could be some in-situ resource utilization but itโd be challenging.
I think that water is an important resource. Once that you have water and electricity, you can produce oxygen easily. And you need large quantities of water anyways.
