Well, everything which produces bluetricity (MJ) would work. Easy way would be Solar Panels, Redstone-Engines (very slow) or Stirling-Engines. If you worked with IC2 bevor and own a IC2-based Energy-System, you should try the Energy Bridgy, an IC Consumer (LV oder MV, depends on your setup) and a BC-Producer.

Generally it's always good to use some more Energy Storage, to be more flexible and reduce Energy-Wasting ;)
