There's a lot of options for getting that energy on the moon mostly various versions of solar either by traditional solar panels or you could use mirrors to concentrate sunlight to provide heat directly.
The latter works pretty well on the moon because the day is pretty long at almost a month. If you get really creative the slow speed means it might be possible to build a giant tracked refinery that slowly circles the moon so it has continuous daylight.
