The "idea" is that, even if it is lower than what other places are using, it is still a lot, we shouldn't just make more bitcoin mining energy spending just because there are others, we should aim at lowering all of them together. Do not show other big energy spenders, drop them too. However, it is not just about spending energy, it is also about the fact that we couldn't produce this energy from renewable stuff that could help reduce the problem.
But many media sources have begun to play the issue, that the energy needs for bitcoin mining are too wasteful, whereas in the statistics or charts that we see is not the case.
The biggest two we have is sun and wind, if we could produce all worlds energy needs with solar panels and wind turbines then we wouldn't have any problems at all and we would be making sure that it is okay to spend as much as we want, as long as it is renewable.
The two energy that you mean, is a source that can be updated naturally and will never end, because it is always renewable in according to the natural methods.
I don't really understand this problem, but I think both of them will never run out, may be the negative side caused is global warming. (Please fix it if it's not true)
But in contrast to the source of electrical energy, they can be created with as many methods, and the development of time has shown that electricity can be renewed, both from the solar system, rivers and other assistance.
Therefor, it is not appropriate if bitcoin is associated with waste of energy, althouls there are still compans that take greater energy sources.
