The only practical method for converting nuclear energy into usable electricity that we current know of in real life (and use) is steam turbines. We use the thermal energy of the reactor to heat water to boil and use the force of it's expansion to drive turbines which force electric engines to turn...

Wind seems to be ok, since it can be pretty unreliable. Solars need predictable number of accumulators, while wind could be much more unpredictable. Wind should surely require some automated backup steam or crazy amount of accumulators. But solars are relatively early stuff too. Maybe solars should ...
