Some IT users "go green" to save the planet. Others do it to save money. Either way, Linux has a lot to offer any green-minded small business.
Lots of other folks have explored this topic recently and have interesting thoughts to share about it. Let's cover the most common reasons why they cite Linux as an effective tool for IT organizations of any size that want to do more with less.
Green guts. Too many software makers behave like a vampire in a blood bank when they get around cutting-edge PC hardware. For years, Linux has been a refreshing exception to this rule.
A good example is what's known as the "tickless kernel." This is a capability built into recent Linux kernels that powers up the processor -- a major power-consumption source in any computer system -- only when it needs to work. As others have noted, it's a power-saving feature that works in devices ranging from netbooks to data-center servers; over time, it can deliver serious savings for companies with even a modest IT footprint.
