This is the question Linux Kernel developer Arjan van de Ven rhetorically asked in an announcement about a new PowerTOP utility released by Intel for detecting what Linux programs and kernel tunables are resulting in the most power consumption. "Why isn't it many more hours? Which software component causes the most power to be burned? These are important questions without a good answer... until now." "Intel is proud to announce the PowerTOP tool, a program that collects the various pieces of information from your system and presents an overview of how well your laptop is doing in terms of power savings. In addition, PowerTOP will provide an indication of which tunables and software components are the biggest offenders in slurping up your battery time. PowerTOP will update it's display frequently so that you can directly see the impact of any changes you are making.""
