      Is it possible to have a climate-friendly variant of bitcoin where miners can only operate using negatively priced electricity (surplus from renewables)? They'd then mostly have the effect of making it more economic to increase the contribution of renewables to base load.

      I don't immediately see how to ensure that only negatively priced electricity (or, at minimum, renewable) could be used. There might be some clever authentication process possible, though...

      *"increase the contribution of renewables to the _grid_", not base load.

      An amusing enforcement mechanism would be to require that power-generating entities participating could only be paid for power in the underlying coin - let's call it greencoin.

      Mining a block would require specifying who you bought your power from, and the price (negative!) paid - i.e., a pointer to the relevant transaction - in addition to the standard things done in mining.

      Lots problems with this. Still, an amusing idea, and if it could be made to work would address two big problems simultaneously.

      (Context for all this: a huge problem with renewables is that they can be difficult to turn on and turn off. Both California and Germany, which have large renewable components to power, often have to pay other regions to take power off their hands, lest it overwhelm the grid.)

          Proof of work as battery, of sorts, storing value instead of electricity? If I'm understanding right I like the idea!

          Hardest part of this proposal is that it simultaneously trades off significantly with Szaboian social scalability. Any sort of supra-protocol consideration likely introduces the need for an oracle (which introduces a host of governance issues Bitcoin is ill-equipped to handle).

          How much of that problem is lack of demand (other places don't want the energy) vs lacking infra to transport/store?
