Yes, obviously AI is emitting way too much. It shouldn't even be producing 0.2% of global emissions, let alone 2%. My main grievance is that no one ever talks about improving industrial and agricultural processes even though they produce around 29% of emissions and 20% of emissions respectively.
Somehow I doubt it. I'd actually expect the capital costs of designing and install the wires to make it unfeasible. Maybe if you had grants for the construction aspect...hmm...
A more likely path seems like electric tractors, maybe with swappable batteries. Really, though, I think I'd need to hear from actual farmers rather than trying to brainstorm in their behalf.
