I mean to say that govts start trying to starve the miners with cutting electricity to mining farms and raiding solar farms (off grid even)
We move to mining block on home electricity connections with less than 10kw load.
You should face reality than what is not. What is happening in the world now from bitcoin critics is that bitcoin is significantly contributing to global warming by producing a greenhouse gas which is carbon gases its mining is producing. Some bitcoin miniers are using green (clean) energy, clean energy are the energies that do not produce green house gases to the environment, like electricity generated from solar, wind, nuclear and well constructed hydroelectric power plants. Out of 100% hashrates generated, over 50% are generated by clean energies, and miners are working towards going fully using clean energy.
Yet, bitcoin contributes less to global warming if compared to other industries that the government are lenient about.
Conclusion
In the grand scheme of things, the carbon emissions emitted by electricity providers supplying the Bitcoin mining network are inconsequential. At 0.08 % of global CO2 emissions, removing the entire mining network from global demand—and thereby depriving hundreds of millions of people of their only hope for a fair and accessible form of money—would not amount to anything more than a rounding error.

About difficulty adjustment, it is done every 2016 blocks which is approximately every 2 weeks. If bitcoin hashrate is increasing or decreasing, the difficulty is adjusted in a way new blocks are mined approximately every 10 minutes on average.
