OVERVIEW

Techniques that improve the operating efficiency of plant facilities, where electrical machinery such as electrical motors have become huge consumers of energy, are attracting attention from the viewpoint of countering global warming. That is because they can implement energy savings in plant facilities and, as a result, restrain CO₂ emissions. The Hitachi Group has spent a few decades in developing and commercializing an inverter-fed AC drive system as one power-consumption-reducing technique for electrical motors. We have applied this technique to plant facilities in various industries and have achieved results, and we have also established an energy saving service that has techniques for visualizing energy savings and reductions in CO₂ emissions, and have contributed those techniques as environment and energy-saving technological support in Yunnan Province in China which is a focus of Japan-China goodwill. In the future, we intend to contribute further to energy saving and CO₂ emission reduction through the development of new techniques.
