If only this blog was about napping, or some other personal energy saving technique. Alas, it is not. This is about a way to save some energy on your computer. A Virginia Tech computer scientist is now marketing a power management software called Granola that is free for personal use, and available for a fee for businesses and servers. I’ve installed it, and haven’t noticed any appreciable difference while it (claims) to be saving me about 20% of my energy usage. The website for the product claims that it can extend battery life on a laptop by up to 10% and desktops can cut energy use by 15-35%.

You can check out the software here, read more about it in a Business Week article here, and watch a video about it below.
