Second law of thermodynamics

I guess this does present the question of how we actually identify exergonic systems considering all systems need an input of energy ( Second law of thermodynamics?). I guess what this really means for my purposes is that these “exergonic” systems use easily available energy that’s already being produced in the absence of the system, so in practice it doesn’t require an additional energy source to sustain itself.

“The Second Law of Thermodynamics is a consequence of a theorem which can be proven in the standard model of physics: If you take a volume of phase space, and develop it forward in time using standard physics, the total volume of the phase space is conserved. For example, let there be two systems, X and Y, where X has 8 possible states, Y has 4 possible states, and the joint system (X,Y) has 32 possible states. The development of the joint system over time can be described as a rule that maps initial points onto future points. For example, the system could start out in X7Y2, then develop (under some set of physical laws) into the state X3Y3 a minute later. Which is to say: if X started in state X7, and Y started in state Y2, and we watched it for 1 minute, we would see X go to X3 and Y go to Y3. Such are the laws of physics.” (Eliezer Yudkowsky, Rationality)
