Example computation. Assuming the university operates 700 computers at 8 regular hours a day, 287 days a year x. 130 kwh x php5.00/kwh, the total cost of electricity used is Php1,044,680.00. This is equivalent to 20% of the total electricity bill of the university.
To conserve energy, all offices are requested to follow one simple rule – Turn computers and printer off when not in use. Do not leave equipment turned on if left for a long period. In general, thirty minutes is considered a long period. Following this simple step can contribute to 10% savings.
