Morphology
The noun phrase is directly compositional: 'electrical' (pertaining to electricity) modifies 'energy' (usable power), so the meaning 'energy produced by electricity' is derivable from the parts. This adjective+noun pattern is regular in English and cross-linguistically common, so a B1 learner who knows both words will understand it.
Etymology
The term electrical energy comes from the image of tiny charged particles moving through a wire like water in a pipe, carrying power. Here electrical points to the moving charge and energy is the power it carries. So, 'electrical energy' means the energy made by moving electric charge that we use to run devices.
