Including for this reason, I do not see any serious fears of obtaining energy to mine bitcoins. Nowadays solar panel production technologies are getting cheaper every day. The construction of power plants is very beneficial even for individuals on the roofs of houses and it can completely solve the problem of cheap clean energy. The sun can still be considered an inexhaustible source of such energy.
That is if the government and the people is on the same page when it comes to a power plant construction or even solar farms, most of the time people are not in favor of power plants near their neighborhood because of the possible ergonomic hazard and solar farms take up a lot of land and people that care about their taxes will not be easily persuaded. Not to mention that a lot of countries are slowly dismantling their nuclear power plant because they favor coal power plant. Only way to save this is for an innovation in power storage and not power generation.
