Energetic optimization Kawpow algorithm

Hey folks,

I was thinking that one of the problems that can make RVN not grow so fast in the future is the energetic consumption of the algorithm. I know that the difficult algorithm is a good balance for that, but in the long-term it can be a problem since it probably going to push hard from the GICs.

My question is: Is there any plan or draft for future updates to optimize the algorithm or is it even possible?

If there's something, where can I find that information?
