    Now, one place it’s more of a problem is in things like transformer windings. There are kilometers of wiring in any of them, so the higher resistance of aluminum is a problem.

    Is it? As far as I know you can use a larger diameter wire to get the same resistance as copper, if your device has enough space for bigger coils.
