$$Z = R + jX $$
R is a real resistance that stores energy as heat and temperature rise which depends on the thermodynamic property of thermal resistance which is impacted by an enclosure to get hotter or cooler by forced airflow.
Everything has some real resistance, even insulators with an electrode-insulation interface (called Effective Series Resistance or ESR) with some capacitance. Also, batteries and inductors have some series resistance.
But X is always a stored resistance referred to as "reactance". Inductors have +ve reactance and Capacitors gave -ve reactance and for sine wave currents the polarity refers to how the voltage "reacts".
The ideal L & C components are considered lossless with no resistance but one must be aware of the actual R values from the design and datasheet.
Energy stored in both L and C may be readily computed and be transferred from or to real power with some R value.
E.g. a Battery is a massive capacitor xx,xxx Farads above a minimum chemical voltage can power a lamp which has resistance.
