Energy Conservation
TEL promotes energy conservation at all sites as a way to help prevent global warming
In addition, TEL's ISO14001-certified sites set energy-saving goals and targets
and work systematically to achieve these..

room facilities used for production and development consume a great0deal of electrical power; therefore, the TEL's various manufacturing

The slower economy caused a downturn in orders in fiscal
2001, so our manufacturing plants and the production and assessment facilities at our R&D facilities were less busy. On the otherhand, new buildings were added at the Fujii area of Yamanashi andKoshi Plants, and the Hosaka area of Yamanashi Plant started testing
