Thankfully that is going to happen anyway through simple economics. Fossil fuel extraction is functionally already a peak technology, out of which every bit of efficiency has been squeezed by over 100 years of frantic and lavishly funded scientific development, whereas solar, battery, and wind technologies have been absolutely plunging in $-per-Kw to deploy and have much much further to go. So governments can try to slow this down as much as they wish, but it's as much a fool's errand as trying to rescue the horse industry in about 1920.

Now as for the question of "why isn't this more efficient technology resulting in savings for, me, the consumer?" I can only encourage you to look at the entire history of extractive, investor-driven capitalism for the answer.
