Software as a service (SaaS) is an undeniably green alternative to traditional computing. It's one form of cloud computing in which people use software applications that are located on the Internet rather than on their own computers or networks. A very common example of it is web-based email. The green aspect of SaaS or cloud computing is that it shifts the computing power responsibilities to a relatively small number of Internet servers and can slow the continual demand for hardware upgrades to meet the needs of new software. Essentially, a software hosting provider can utilize a server more efficiently than you can in your office; it can also make setting up and managing your software a whole lot easier. As you rely more on the cloud, you may find that you rely less on an in-house IT person. It also usually lowers your upfront costs since you no longer have to buy and maintain the server or the software. But is it the right solution for you and your organization?

Risks

Since these services usually charge some sort of subscription fee, the lower upfront costs need to be balanced against the generally higher operating costs to determine what is right for your budget. Check out the thoughts and concerns of some of our forum users in this thread (read past the first few posts about the initial article to get to the real discussion). Their main concerns were around security, potential for data loss and availability. Major SaaS providers like Google, Amazon and Microsoft have had significant outages causing inconvenience to their users, but more importantly, one actually lost data in the process.

How do you choose computer hardware? Price? Features? Sales pitch? We urge you to consider using some standards that have been generated to help us understand the environmental impact of computer and tech hardware.

You are probably familiar with the EPA's Energy Star program, but do you know about EPEAT certification? EPEAT is a system that helps purchasers evaluate, compare and select electronic products based on their environmental attributes.

All EPEAT-rated computers are also Energy Star compliant. That is one of the EPEAT criterion. However, not all Energy Star computers and monitors are EPEAT-rated. Energy Star rates a wide variety of hardware, from refrigerators to TVs. They look only at the energy efficiency of the hardware. EPEAT has many more criteria, some of which include the types of materials used in creating, packaging, and shipping the hardware. Energy Star is a U.S.-based rating system. EPEAT, while developed in the United States, has now been adopted by over 40 countries around the world. Both have searchable lists of compliant hardware.

This is part two of a two-part series about virtualization. In the first post, we attempted to explain what virtualization is and why you should care about it. Here, we explain more about server virtualization and share our own positive experience with it.

Server Virtualization

If your organization has multiple server computers that supply your computer system with email, Internet, print services, databases, data back-ups, password authentications, a place to store documents, and more, then server virtualization is something that can save your organization money and energy. Virtualization software can cut server power consumption by up to 80%.

Server virtualization is software that allows you to optimize a single server computer so that it is able to do the work of multiple servers. Did you know that most servers are only utilized between 10 and 15%?

Don't know what virtualization software is or even care? Well, you should.

If you aren't using it directly in your office, I bet you are using it through one of your software providers without even knowing it. Is your website or email hosted somewhere outside your office? Do you use Salesforce.com or an online donor database? I bet they are using virtualization. Most large services who host software like the ones I mentioned above should be using this technology if they aren't already.

This is the final post in a four-part series. Part 1 of this series listed the five actions we recommend that you take to reduce the power use of your computer. Part 2 and Part 3 explained in more detail how you could easily complete four cost-saving actions. This post explains the fifth and final action in this campaign — how you can multiply the positive impact you have had on the environment by getting others involved.

Softchoice found that 93% of PCs are still running Windows XP, which did not default to having power management turned on.

In Can Windows 7 make PCs Green? Todd Bishop writes, "With hundreds of millions of PCs draining batteries and tapping into power outlets around the world, even a small tweak in Microsoft Windows can influence global energy consumption."

With numbers like these, it is imperative that we convince as many people as possible to reduce their IT power use.

One of our forum hosts, Dave Welp, suggested these quick, power-saving tips:

1. Look for abandoned telecom equipment like old modems and PBX; search for un-utilized or under-utilitized servers or computers used by former staff and volunteers.

2. Clean up your power strip: Look for plugs to those old calculators or speakers.

3. Electronics continue to consume electricity even when in an off state, so either turn them off at a power strip, or unplug them entirely. 

More tips like these can be found on our energy reduction mini-tips page.

Part 1 of this series listed the five actions we recommend that you take to reduce the power use of your computer. Part 2 explained in more detail, two cost-saving actions and tells you how to complete those two actions. This post, fills in the details about two more recommendations.

Upfront Cost, but Should Save You Money Within the Year

3.    Order a smart power strip.

Light green: easy individual actions

These types of power strips automatically turn off your peripherals (monitor, speakers, desk lights) when you shut down your computer and generally consume only 1 watt while on. Plug your computer into the main (switching outlet) and then plug your monitor, speakers, printer or other accessories into the other outlets. When you shut down your computer, the peripherals will shut off automatically. These strips also have always on ports for items like a fax machine that would need to remain on after the computer is off.

This is part 2 of a four-part series.

Part 1 of this series listed the 5 actions we recommend that you take to reduce the power use of your computer. This post (part 2) explains two of those actions in more detail and tells you how to complete these two actions. Parts 3 and 4 offer more detail about how you can make the other three changes.

Reduce Your Energy Use at No Cost and Save Money Instantly

1.    Set power management on your computer(s)

Light green: Easy Individual Actions

All major operating systems released in the past ten years come with power management built in, but not necessarily turned on. What is power management? It's the ability to set your computer and monitor to automatically go to sleep or shut down after a period of inactivity. Climate Savers Computing are the experts at this and have all the information you should need to accomplish this task. They even have step-by-step guides. We urge you to sign up for CSCI membership either as an individual or affiliate: it's free and it's a way to build momentum for IT energy conservation. They can keep you informed about the latest ways to reduce your IT footprint. They even have a wonderful, searchable list of energy-efficient hardware and software products that help with IT energy reduction.

Welcome to TechSoup GreenTech's Unpower Yourself! campaign. For this campaign, we have compiled a variety of information about IT energy reduction on our web pages.

Global warming is happening because of a buildup of greenhouse gases in our atmosphere, most of them produced by power plants that burn fossil fuels to generate electricity. Information and communications technology consumes a good deal of electricity, much of which is wasted as heat, consumed by computers and monitors needlessly left on, or used to cool hardware that is not running efficiently.

More than half the electricity used by IT is outside the data center and it is very easy for you to make small changes that will have a significant positive impact on both the environment and your wallet. It's not always easy to get a significant number of individuals to take these easy actions, but we can reach more people with your help.

Here are five things you can do quickly to decrease your IT energy use:

According to the Climate Savers Computing Initiative, "Don't use a screen saver. Screen savers are not necessary on [most] modern monitors and studies show they actually consume more energy than allowing the monitor to dim when it's not in use."

Instead turn on the power management features built into your computer. Power management is what allows your monitor to automatically turn off or puts your computer to sleep after a period of inactivity. You can find step-by-step instructions for most computers at Climate Savers Computing. Look in the right hand column to find the operating system that you are using.
