If you reduce energy consumption of training a new model by 25%, OpenAI will just buy more hardware and try to churn out a new model 25% faster. The total consumption will be exactly the same.

And they're 100% justified to do so, until they hit another bottleneck (when there is literally not that much Nvidia hardware to buy, for example.)

There's no gain to be had there at all. Any optimizations that reduce resource usage per output will be gobbled up by just making more output.

OpenAI released an open source model only because they are capped on growth right now by the amount if hardware they have. Improve resource efficiency and you better believe they'll just crank up use of said resources until they capped again.

I imagine there's a lot more to be gained than that via algorithmic improvements. But at least in the short term, the more you cut costs (and prices), the more usage will increase.
