That only works if it becomes part of the BTC protocol that you can only mine if the electricity comes from renewable, non-polluting sources. Otherwise, due to solar not being the cheapest, most accessible source of energy everywhere that people want to mine BTC, you'd have lots of people choosing to increase greenhouse gas emissions in order to fill their own pockets.

It would be interesting to see estimates of the cost of those greenhouse gasses, in terms of extinct species, effort to clean up the atmosphere, or other expensive/bad things that can happen when you claim that increasingly using energy in non-efficient ways is just fine. Are these costs higher or lower than the value of the money created?

Perhaps BTC is sustainable, but your argument certainly does not refute the article's claim - at least, until we've already solved our energy & pollution problems.
