Energy Efficiency Encyclopedia – PC Power Management

This week, I wanted to take a step back and talk about PC power management. Companies that focus on sustainable technologies frequently throw this term around, but lots of folks today still aren’t sure exactly what PC power management is. And I’m not just referring to people outside the tech sector. In fact, last week I mentioned the term to a friend of mine who works at a large software company, and his first instinct was that power management referred to a computer’s processing power. Point being, it’s worth explaining again.

Within the context that Verdiem uses it, PC power management is all about conserving a PC’s energy consumption to save money and indirectly reduce carbon emissions. The most successful way to manage PC power consumption is to make sure that when you are not using your PC, it is either turned off or moved into a lower power state (like sleep mode). Operating systems, such as Windows Vista, enable users to better manage their PC’s power settings. Unfortunately, people often incorrectly assume that power management functionality will limit their PC’s performance, so frequently turn off the power-saving features on their machines. The reality is that PC power management software is generally built to balance saving power with ensuring the end user’s needs don’t suffer, so won't negatively affect performance.

Given rising energy costs, in conjunction with a poor economy and the increasing threat of global warming, saving money and reducing carbon emissions has become more important than ever before. Conserving your PC’s energy consumption is a great way to simultaneously reduce costs while also positively affecting the environment.
