I think they randomly spawn one green monolith per planet/moon, so it's different each game.
>how do you produce electricity on your rover?
It's got an radioisotope thermoelectric generator. It doesn't produce much power, and I thought I was going to need more to run the motors, but the nukes are pretty expensive so I went with one. Just the one RTG accounts for half the cost of the rover, minus the booster that got it there. Turns out the rover is light enough on Duna that the wheels barely need any power and one RTG was pretty much perfect.
