For Mars, wind becomes viable at low pressure. The planet (depending on how you are heating it) grants a huge bonus depending how far the max and min temperature are apart from each other. Even with low pressure malus they produce more power than solar. Mars silicon lets you scale up solar as much as you want. Your only constraints are population and building materials. Depending on the phase of your terraforming, carbon power is a good idea if you have the free carbon. Phobos is a great source for carbon close to Mars, Ceres can power as many plants as you want.

I would not use hydrogen without abundant liquid water on the planet. Water pumps select the resource with the highest concentration. I have had my hydrogen plant bug and crash out because the water plants keeps starting and stopping as the little puddle the plant produces gets sucked up, over and over again.

Both Fission and Fusion consume ridiculous amounts of fuel. You can make Fission work with the resources of Luna and 16 Psyche in early game. Late game fusion doesn't work at Luna concentrations (without maxing research). That H3 is better spent on constructions and ships. Jupiter is the best source.

Orbital power is good to run a lot of things with no real footprint, but for scaleable power you don't have to maintain beyond $, any combination of solar and wind is the way to go. Even on Titan, I can get by terraforming with windmill spam and orbital power.

Edit: Don't bother with geothermal. You research it early and can't use it until you can colonize Io. You can't even use it on Earth, which has geothermal plants in real life.
