- energy loss in resource extraction and refinement (steel, aluminum, plastic, etc, etc)
- manufacturing energy use
- shipping energy use
- disposal energy costs of old device (including recycling costs)
- all the pollution in the above, versus pollution from local energy sources
It's entirely possible that an energy efficient fridge that lasts 2 years, could cost more energy than a fridge from the 60s that keeps on running.
So outside of "cash cost" even the energy cost may be higher!
