Technological change is an important source of economic growth. In C3IAM, in addition to the exogenous augmentation of the supplies of labor and natural resources, energy consumption per unit of output decreases externally over time (the so-called autonomous energy efficiency improvement index, AEEI), which is a heuristic representation of non-price-driven changes in energy use over time[1].
Technological change in electricity sector also has been specified with two advanced generation technologies: natural gas combined cycle technology with carbon capture and sequestration (NGCC-CCS) and integrated coal gasification technology with carbon capture and sequestration (IGCC-CCS). If these technologies are economically competitive with existing technologies, they will endogenously enter.
