Bitcoin, a Gift to Environment

From the abstract: "This article will address this debate and try to understand Bitcoin's use of energy, and more specifically its carbon impact today and tomorrow. In this article, I will not engage in a war of figures, rather put those figures in perspective and explain the underlying trends of proof-of-work. I will also try to explain what a Bitcoin world would mean in terms of environmental but also economic sustainability. All in all, we end up discovering that Bitcoin may be much more of a hope than a threat in the sustainability debate."
