Energy Conservation
At the TEL Group, we promote energy conservation as a means of preventing global warming. At all
our facilities, we universally strive to reduce power consumption through such means as turning lights
off during lunch hour and regulating air conditioners’ temperature setting. At ISO14001-certifiedplants, we systematically promote energy conservation toward specific objectives and targets.

■ Major Energy Conservation Measures• Reduction of power consumption by lighting andoffice equipment (at all facilities)• Regulation of air conditioning temperature setting(at all facilities)• Design and operation of capacity utilization
reduction system for demonstration equipment(Yamanashi)• Turning-off of vending machines at night (Osaka)• Partial suspension of clean room use (Saga)• Scheduled equipment shutdowns (Ozu, Yamanashi)• Turning-off of compressors at night (Yamanashi)• Power saving stickers, which call for energy
conservation, affixed to equipment used for productdevelopment and the like. (Sapporo)■ Aggregate Power Consumption
The bar graph at right shows the trend of the TEL Group’s aggregate power consumption on ayear-to-year basis. The linear graph shows changes in the basic units for each year, calculated by
dividing total power consumption by sales for each year. For purposes of comparing yearly results,
the basic units (used to show the relationship between sales and total power consumption) arecalculated by taking the results for fiscal year 1997 to represent 100 points (100%). In fiscal year
1999, we started keeping a tally of the amount of power consumed by our non-manufacturing
facilities, in addition to that by our manufacturing plants.
At our manufacturing plants and research facilities, production and assessment equipment havebeen operating continuously at full capacity throughout the fiscal year 2000. As a result, the TELGroup’s aggregate power consumption increased in fiscal year 2000 compared to the previous year.
However, the basic unit improved considerably, from 170.7 points in fiscal year 1999 to 96.8
points in fiscal year 2000. This represents a drop of over 40 percent, or, to 56.7% of the previousyear’s figure. This figure is even lower than the figure for the reference year of fiscal 1997.
We aim to further reduce our aggregate power consumption by continuing to promote energy
conservation on an ongoing basis at all our facilities.

allowing for an overall reduction in the number of lights used through an increase in luminosity of bulbs
used throughout the plant. We also shut off the air conditioning at regular intervals. The result was a 1.1%
(120,000 kwh per year) reduction in power consumption• At our Osaka branch office, we installed timers on beverage vending machines. The timers conserve energy
by automatically turning the machines off at night.
