Fuji Electric is participating in the voluntary action plan targets for the industry set by four electronics industry organizations* so as to help Japan achieve the goals of the Kyoto Protocol. Since FY2007 we have engaged improving our energy conservation so as to meet our voluntary goal of reducing the volume of Japan’s CO2 emissions from energy use in FY2010, which falls in the middle of the first target period of the Protocol (2008–2012), by 6% in comparison with the benchmark year of FY2006. Examples of energy conservation measures at each of our sites have been compiled in a database, and we have been conducting energy conservation analyses of each domestic production base.
In FY2010 we engaged in a variety of measures, including switching to more efficient lighting, such as LEDs, and air conditioning systems, and reducing energy waste through clean room temperature and humidity controls. As a result, we reduced domestic CO2 emissions by 179,265 tons, or 19.9%, compared to FY2006, hitting our target. Also, we succeeded in reducing overall energy use (electric plus fuel use) in FY2010 by approximately 11% owing to our energy conservation initiatives since FY2007.
We also held the Energy Conservation Case Report Conference for the sharing of energy conservation data. In addition, we began conducting energy conservation analyses at two overseas bases so that energy conservation efforts can develop at a level parallel to our domestic bases.

The Matsumoto factory is engaged in semiconductor production, and as such we consume a lot of energy.
Therefore, we have been engaged in serious energy conservation activities since FY2007. In addition to improving the efficiency of the power supply we derive from cogeneration, we have also been able to reduce greenhouse gas emissions and water usage broadly by uncovering energy demand side issues, such as those involving our clean room air conditioning. We would like to provide this kind of know-how to other Japanese and overseas bases as well so that bases worldwide can develop their programs at a level parallel to ours and proceed with measures to reduce energy and resource use as well as greenhouse gas emissions.
Facility investment has become tight due to the changes in the economic environment since the Lehman shock, so continuous investment even in energy conservation measures, which provide good ROI, has been difficult. Nonetheless, we are continuing to improve our controls and diagnostic technologies so as to uncover “hidden” energy issues at our sites.

Nuclear power is prohibited in the Philippines, so most power comes from thermal, with hydro, geothermal, and wind also in use. Nonetheless, chronic power shortages remain a problem as the nation deals with issues such as quality, price, and supply volume.
Fuji Electric Philippines, a semiconductor devices manufacturer, is actively engaging in energy conservation so as to cope with power shortages. Such efforts include raising the temperature of cooling water for equipment by 1°C, and reducing the operating frequency of the fan motors for cooling systems from 45 Hz to 60 Hz by installing inverters.
As a result of these energy conservation measures, the company achieved electricity savings of 26% in FY2010 compared to the previous fiscal year. In recognition of this achievement, Fuji Electric Philippines received the Energy Ministry’s Don Emilio Abello Energy Efficiency Award for superior efficiency improvement.
Henceforth, the company will continue to strive to produce even greater results by having each individual employee give serious consideration to the most effective means of energy use.
Construction of a new facility for vending machine production at the Mie factory was completed in February 2011. The new facility will enable order-made vending machine production according to customer specifications, and will also shorten production lead time.
The new facility, which went online in February, not only has greatly shortened line length, but also concentrates a number of production lines, such as for sheet metal, painting, assembly, and testing, which had previously been dispersed. This reduces the amount of space required by 40%. Also, by incorporating energy-saving production equipment design and energy-conserving equipment, a 20% reduction of annual CO2 emissions compared to the previous production facility has been forecast.
This facility has succeeded in reducing the amount of energy used to produce a single vending machine by 23% (22kWh→17kWh) by making energy use in the production process “visible” and by improving productivity.
