There are many different types of power, that can easily be worked into Genisis... It depends, however, on what the planet is going to consist of.
Generally, anything that generates heat can be used as a power source. Already used and existing power sources:
Geothermal:
Must be built near some surface vent to be of any use.
Hydrodams:
Typically use water, but not neccessary. Any place there is a running liquid, the energy can be tapped by turbines.
Nuclear:
Wherever there is heavy elements, they can be split to generate power. Uranium is considered the best at this time.
Fusion:
Tokamak in OP2. Turns matter into high energy plasma state and uses megnetic force to keep the plasma from melting the coil walls. Can genereate a lot of power (by today's standards) and can run on any lighter element, past iron. The best combination involves Deterium and Tritium (made from Lithium).
Wind Power:
Any planet with a reasonably thick atmosphere can harness the wind. As far as I know, bob has an atmosphere. Possibly a very turbulent one, so this would actually be quite the valuable structure.
Solar Power:
Solar generaters on the surface of bob! Assuming its atmosphere isn't too thick/turbulent (too much particulate matter from a lot of wind makes this useless) Can also be done op2 style, where energy is "beemed" down to the surface.
Biogas:
Something being looked into today, using Methane, which EVERYONE makes in abundance, to produce power by burning it. Renewable resource (obviously)
MHD Generator:
Assuming bob has a strong enough megnetic field, the origional MHD may still be applicable.
If bob has an ionized atmosphere...
Lightning Power:
Lightning rods on bob, as far as the eye can see. Absorbs the strikes, and shunts the energy into the colony (perfectly possible. Right now, we just dump the energy into the ground)
If bob is Volcanic....
Lava is very thick. Assuming there is an active lava run that does not solidify often, a generator can be built on it. Also assuming that a material exists that can handle the heat of molten rock.
Thats all I could think of... Other then the obvious fossil fuels, but thats if Bob ever even supported life.
