Approximately 50% of the total energy supply in Japan has been consumed as thermal energy. On the other hand, approximately 60% of the primary energy supply has been lost as waste heat. Therefore, full utilization of thermal energy would be important to promote the energy conservation and to contribute to the global environmental protection technologies. In this research, concerning to utilization of unused waste heat, the possibility of heat recovery from the water including fouling, such as calcium carbonate, is studied. The classification of fouling, the investigation of the quantity of total recoverable energy, the deterioration of the performance of heat exchanger are studied and the reduction of global warming by the heat recovery is estimated. Concerning to the research of a new Energy Flow Map, total amounts of energy consumption(Industry-use, Transportation-use, and Public-use) are listed from a human-life point of view. This table is classified into 5 main categories which are Clothing, Food, Home, Job/School and Society/Service. Those are classified into some items further. Energy utilization which are manufacturing energy, manufacturing energy of raw materials, energy loss , and energy release into environment include loss of energy transformation were calculated and listed. Energy consumption were calculated from the statistics of energy utilization and the table of industry utilization. These values were compared with 5,150W which is the average energy consumption at 1991. So far 3,800W is classified approximately, but 25% is still unknown. After this , we are trying to reduce unknown value by making the most of the table of industry utilization.
