Isn't the security of the blockchain fundamentally tied to the mining difficultly?

I don't see how you could significantly reduce the energy usage without sacrificing security (unless you make structural changes such as moving to POS)

You could reduce the energy use per-transaction if the block size limit was increased.

That's not gonna happen at this stage however.
