Economics: "The core finding is that simply maintaining our current economic wealth requires continual energy sustenance. Like a living organism, civilization requires energy not just to grow but also to maintain its current size or wealth. All components of civilization, whether human or physical, have no innate value; instead they acquire economic value through mutual connections since these enable the circulations that define humanity. These circulations between and among us and our stuff require a consumption of energy. Viewed very generally, our total civilization wealth is directly tied to this energetic power through a constant. "
So even if emissions are zero, growth will increase the amount of installed human infrastructure and human activity, which means there will be more heat. No matter what fuel is used. No. matter. what. fuel. is. used. At 2.3% growth, human infrastructure/activity will double in 30 years. Due to 2nd Law of Thermodynamics, energy cannot depart earth faster than a fixed rate based on [fixed] surface area and [fixed] energy transfer rate.
