Moreover, a miner pays for the energy, not as if the energy used is free, it is left for the energy producing company to step up if it’s affecting them
That's definitely an issue. Ideally, miners would buy excess energy at a discount where it's abundant, rather than adding load to a high-demand or low-supply grid. There already exists some natural incentive to promote this: Where electricity is more abundant, prices are cheaper. I think as we see more businesses of scale enter the mining sector, we'll see an ever increasing share of operations moving towards more sustainable situations where they won't threaten power grids or drive prices up.
There's also the likelihood that green energy sources like wind and solar generation will become increasingly efficient and accessible to the market. That will lower the footprint of what miners consume beyond excess supply.
