Clean Factories - Factory Energy Conservation

Our energy consumption has increased in the device segment in Japan, which manufactures semiconductors and plasma display panels, and in China where coal is the primary energy source. These two elements account for a significant percentage of our total CO₂ emissions, and therefore are subject to priority reduction initiatives. For device factories in Japan, the specialized technologies of our in-house energy service company (ESCO) and the Production Technology division are being fully utilized. The factories receive focused diagnoses as a joint project with model factories. Successful initiatives are then implemented at other device factories. In terms of measures for overseas factories, especially those in China, activities have been conducted under a Three-Year Plan starting from fiscal 2005 to establish an effective energy management system.
   In fiscal 2007, improvement model cases were collected through an in-house energy conservation competition. From 213 applications, the best case was commended at a presentation meeting. All the model cases are incorporated in a database and are available on the intranet.
