Marchetti, Cesare
Cesare Marchetti (1927-), an Italian physicist and systems analyst noted for his pathbreaking work in modeling long run patterns of energy substitution, carbon dioxide sequestration, and the production of energy from hydrogen. As a senior scientist at the International Institute for Applied Systems Analysis (IIASA), Marchetti developed the first mathematical models of the long run pattern of energy substitution in industrial economies, i.e., from wood fuel, to coal, to petroleum, to primary electricity (1975). He was among the first to discuss technical aspects of producing hydrogen as an energy carrier (1969) and to propose pumping carbon dioxide into the oceans as a means of climate change abatement. Marchetti made important contributions to the energetics of agriculture and the long run modeling of demographic transitions.
