Would geothermal work? I can't think of any particular reason that the heat of the earth should vary much with time (feel free to correct me if I'm wrong in this assumption), and energy production should be more controllable because to my understanding it generally just makes steam for a turbine like more traditional power sources.
Geothermal is really expensive in most parts of the world. It costs a lot of money to drill deep enough and to have enough capacity.
Plasma deep drilling is starting to hit the market which should make geothermal available pretty much everywhere. The sad thing about current geothermal is that it's not even used in areas where you do have heat near the surface, the reason is that geology is quite unpredictable and every borehole is a crap-shoot between hitting the jackpot and having to pay damages out of your arse because people's houses collapse. Deep drilling has none of those issues.
