- dredmorbius 5y agoThe more usual description is of the embedded energy of various products and services. Electronics have an exceedingly high embedded energy, given the tolerances, purities, rare minerals, etc., utilised within them. https://en.wikipedia.org/wiki/Embodied_energy https://en.wikipedia.org/wiki/Embodied_energy The bond-energy of goods is less significant, particularly if that bond-energy existed in the raw form of the material (e.g., wood or plastic (petroleum)). It's the energy used in transforming, processing, and transporting materials that matters.
