Genera l Implication s o f Mergin g Several observers have pointed out that the shift to newer technologies is accompanied by a diminution in both material and energy use (Larson et al., 1986, pp. 24-31; OECD,1989, p. 66; Junne et al., 1989, pp. 128-142). Information machines require far less energy and material than steel factories, steam engines, automobiles or other 19th and 20th century technologies. Further, information technology when incorporated within these other older technologies can make them run more efficiently with less material and energy use.
