     · 1. Introduction. The Romanian 1 economist Georgescu-Roegen is best known for pointing out somewhat controversially—but correctly—that high-quality low-entropy resources such as oil and gas, and metals, are converted by the economy into high-entropy wastes. He went on to assert a ‘fourth law’ of thermodynamics, namely that mass, like energy, becomes increasingly unavailable and that
