Lunar energy is not the only energy with which one may power a spell. There is solar energy as well, whereby one may draw on energies associated with the phases of sun - dawn, midday, sunset and midnight. There is also seasonal energy - spring, summer, autumn and fall.
Likewise, to power a spell one may draw on planetary energy. There are general daily planetary correspondences. More optimally, one can infuse a large amount of focused energy into spellwork by knowing how to calculate planetary and halachic hours, and by knowing the associations linked with the various results.
