I have solar, and it's mostly (90%) not being utilized and sent back (I overspecced when NEM 3.0 was about to hit). Prior to this, it made sense to sell it back to PG&E. Now I'm looking for uses to only sell back what it makes sense to sell back. Obviously transitioning gas therms and replacing with electric is underway (for heating/cooking), as well as charging an EV but there will likely still be excess. So mining bitcoin? But only if I can spin up & down the mining when solar ramps up/down.
