Abstract
This paper describes current status of modeling energy usage patterns for
PCs, provides insight in their energy consumption, energy costs and CO2
emission. It also provides possible solutions for improving energy
efficiency and energy savings. The study involved analysis of two different
mode settings (High Performance and Power Saver mode) of same
computer and gaming test case study. Usage patterns for both modes were
modeled based on Intel®'s EEP methodology. Workload was simulated
with StressMyPC freeware software. PC energy consumption while
executing workload was measured with Trotec® BX11 measuring device
during 15 days testing period, 8 hours a day. Computer and monitor were
separately observed
