One issue I have never seen addressed is the consideration of how much
energy is used to BUILD the components of the systems (solar arrays,
wireless chargers, etc.), and the associated pollution (read that: global
warming) resulting from that construction/production. Resources/Minerals
must be mined; then processed; then used in the production of the devices
in question. All of this takes energy. Probably more energy (including
fossil fuel energy) than would have been used if we spent that energy
(joules) directly on the work (watts, ft-lbs, calories, BTUs, etc.) to be
done (driving a car, heating/cooling your home, et-al). You are
saving/buying nothing if that EXTRA energy you use OVER the direct use of
the original expenditure EXCEEDS what you save at the end with the new
devices/systems/etc. Remember: Some of that extra expended (wasted) energy
is coming down your antenna feedline as noise.
