No real energy source or device is 100% efficient because of the laws of thermodynamics: the second law requires some energy to be lost as waste heat (entropy increase), so you can’t convert all input energy into useful work. Practical losses—friction, electrical resistance, imperfect chemical reactions, heat leakage and material limits—also reduce efficiency. For heat engines there’s a fundamental Carnot limit; for batteries and solar cells, recombination and resistive heating cause unavoidable losses.
