It's not that direct though. As a business I seek to use the least amount of energy, but I buy whatever is available. Usually I have one choice. And electricity is typically a small part of my costs and revenues, one of many bills and choices I can pay or make.
As a power company, I sell whatever I have. I might develop other large power generating plants, but my customers are usually stuck just buying what is available, paying whatever price I charge. I have little incentive to innovate, since competition is mostly non-existent, and whatever comes up takes years to build because it would have to provide for a huge number of customers.
As a miner, my electricity is my main operating costs covering 99% of my expenses. And I'm more mobile, so while it could take a few months, I could pick up and move my operation somewhere where power costs become better. And I have a direct incentive to fund R&D into energy production if it helps me reduce some of those costs.
And if some country goes Idiocracy, like China did, miners pick up and move, like they did.
