Intel® Power Efficiency Community
Power Bytes
Coming Soon: Our brand new show – Power Bytes. Designed to give you up to date information on a bi-weekly basis in bite-sized segments.
Focus Areas
Get all the information you’ll need to ensure that your applications are performing as power-efficiently as possible. Whether you’re trying to save battery life or help reduce your customers’ data center utility bill, the Power Efficiency Community gives you the tools to reduce your software’s power consumption.
Battery Life
Ever-increasing dependency on mobile devices has put an increased need on power-efficiency. Batteries have limited output, so we need to take the necessary steps to ensure that our applications aren’t power drains. With the right programming approached, Software can play an important role in reducing the power used on mobile platforms and extend the battery life.
Essential Content
- Developing Green Software - This paper describes the characteristics of Green Software and the software design considerations and methodologies to improve software energy efficiency.
- Energy Efficient Guidelines - These guidelines focus on how to optimize applications for energy efficiency. It is beneficial to the application developer to look at the system wide power efficiency as running background applications might affect or interact with the target application. For instance a background virus checker might slow down file access or impact generic performance when active. To eliminate or reduce background impact, try to disable or minimize potential system culprits when measuring application energy efficiency.
- Energy Efficient Criteria Checklist - This checklist can aid you in creating energy-efficient software applications, with an easy to review list of ideas and tips. The checklist is OS agnostic except where otherwise noted.
- Fine-Grained Application Analysis For Energy Aware Computing - This white paper describes how software “idle” behavior can have a negative impact on battery life. It also explains how to find the root cause of an application behavior that impacts battery life and the steps necessary to mitigate it.
- Intel® Power Checker - Quickly Measure your application’s power efficiency.
Energy Usage
When laptops aren’t running on battery, they’re likely plugged into the corporate power grid, drawing power along with desktops, workstations and servers. With corporations looking for ways to “Go Green” and reduce their power consumption, your software needs to be optimized to reduce its power-usage requirements.
Essential Content
- Intel Energy Checker - The Intel® Energy Checker SDK provides a way to measure how "green" a system is by measuring the amount of productivity done by a system vs. the energy consumption of that system.
- How Green is Your Software - A quick 1-pager to set the tone for using the Intel® Energy Checker.
- Developing Green Software - The tips and tricks offered for battery savings can be used to reduce power consumption.
- Power Analysis of Disk I/O Methodologies - This paper provides guidelines on optimizing the power during disk I/O in various usage models along with the power impact.
- Energy Efficient Guidelines - These guidelines focus on how to optimize applications for energy efficiency. It is beneficial to the application developer to look at the system wide power efficiency as running background applications might affect or interact with the target application. For instance a background virus checker might slow down file access or impact generic performance when active.

This is YOUR community and you get to help set the direction. Read the articles, read the blogs, download the tools and post your questions on the forum. If you feel so inclined, go ahead and answer some of the forum posts if you think you’ve got the answer. If there are site changes you’d like to recommend, go ahead and post it in the forum. We read them all.
Getting Started
Energy-Efficient Software Guidelines
These guidelines focus on how to optimize applications for energy efficiency. Note that the goal is not to provide system-level optimization suggestions, but rather for application-specific optimization.
Energy-Efficient Software Checklist
Checklist for creating software applications that are energy-efficient. This checklist is OS-agnostic except where otherwise noted.
Energy-Efficient Platforms – Considerations for Application Software & Services.
This whitepaper outlines the fundamentals of the mobile platform power saving features including how software behavior affects platform energy-efficiency,describes how to identify software issues that negatively affects platform energy-efficiency, and discusses the details of how to fix and optimize software energy-efficiency.
