Epson Reports on Emergency Energy-Saving Program
Epson launched an emergency energy-saving program at all of its Japanese business sites in response to summer energy shortages resulting from the earthquake and tsunami on March 11, 2011. The program, which aims for a 15% reduction in power consumption year-over-year, is ongoing.
Even before this program, Epson has long sought ways to minimize energy usage, developed the technologies needed to do so, and deployed those technologies across its workplaces and business sites. However, this program was not merely an extension of past efforts; it required the establishment of teams of internal specialists, including energy specialists and electricians, who carefully patrolled Epson's business sites to look for anything that was overlooked or for new innovative ways of saving electricity in order to accomplish the difficult task of cutting energy usage by 15%. Over nine months through February 2012, the program fell slightly short of its target but still managed to reduce power consumption as follows.
- Reduction rate (year-over-year): 14.4%
The various improvements from the program were made into a program (in Japanese and English) that is being shared throughout the group on the corporate intranet. New measures are being studied and implemented based on this program.
Given that the power supply issue will not be going away, Epson will continue to pursue energy-saving activities with renewed vigor in the new fiscal year, which starts in April 2012.
Improvement example 1: Blocking air leaks
Air compressors are commonly used on the factory floor. However, a lot of electricity is consumed making the air. It's possible to save electricity by finding and then blocking air leaks.
