title: What is the relation between CPU utilization and energy consumption?
body: <p>What is the function that describes the relation between CPU utilization and consumption of energy (electricity/heat wise).</p>
  
  <p>I wonder if it's linear/sub-linear/exp etc..</p>
  
  <p>I am writing a program that decreases the CPU utilization/load of other programs and my main concern is how much do I benefit energy wise..</p>
  
  <p>Moreover, my server is mostly being used as a web-server or DB in a data-center (headless).</p>
  
  <p>In case the data center need more power for cooling I need to consider that as well..
  I also need to know what is the effect of CPU utilization on the entire machine power consumption ..</p>
