Monitoring energy consumption and
identifying the issues

Hitachi has been systematically upgrading its production equipment to highly efficient equipment. Moreover, with its energy management system, Hitachi has been "visualizing" its energy consumption, and using the system to identify various issues and take necessary actions such as finding and reducing wasteful energy use.

Use limitless natural energy.

Some of our factories and offices use electric power generated with sunlight, wind power, and other renewable forms of energy in its lighting and air-conditioning. In fiscal 2014, the Hitachi Group as a whole generated as much as 3,440 MWh in total.

Replace the conventional lamps with LEDs.

At both factories and offices, Hitachi has been introducing LED lighting, which is highly efficient in energy conservation. This minimizes energy consumption because these lighting are used every day.

Use limited water resources ingeniously.

With an ongoing increase in production, particularly at seriously water-lacking locations outside Japan, Hitachi works to minimize its water consumption. We use recycled water in the manufacturing processes and saves water used in the factories.

Factory VOC

Manufacturing that does not impact people or nature

The volatile organic compounds (VOC) in paints and cleaning agents used in factories are believed to cause photochemical smog when released into the atmosphere. Hitachi is working to reduce VOC emissions by switching to substitutes for VOC-containing materials and reviewing its work processes.
