Constraining the energy gobbler. [Waste heat utilization, co-generation, fuel-cell use, more-efficient electric motors, etc]

Industry, responsible for 40 percent of the nation's annual energy consumption, has been targeted by the Department of Energy to use innovative technologies that will cut fuel use by 20 percent and lower fuel costs. Key elements in the program are better control of combustion, recovery of waste heat, co-generation of electric power and process heat, improved motor and induction-heating-equipment efficiency, and on-site fuel cells. A summary of the present status and future potential is given for each of these areas of energy management. Four energy-management schemes ranging from personal surveillance to total energy control are summarized to indicate the equipment required, programs changes, vendors, and the advantages and limitations of the scheme.
