If all the energy is actually being released by the wire through resistance, then why's the potential of the ground changing?

The potential at the ground isn't (or shouldn't) be changing

which is the same thing as saying the power isn't being dissipated in the ground. So the power isn't being "dumped to ground," it's being dumped through the wire.

So basically, two options: 1) you dissipate power in the load, which is what should happen, and everyone is happy. 2) you dissipate power across your ground, which means ground is no longer really ground, and all sorts of nasty and dangerous things can happen.

Does lightning cause those nasty things to happen?
