La responsable IT d'une école américaine dit « Je suis un partisan des initiatives vertes », dit Kebo, qui déploit des serveurs en lames et la virtualisation des clients. « C'est mon travail de faire fonctionner le service informatique avec efficacité et efficience. Mais ceci est autant les économies de coûts suite à des réduction de consommation énergétiques et les réductions de refroidissement dans le centre de données que le fait d'être vert. Ils vont de pair. » (“I’m an advocate of green initiatives,” says Kebo, who is deploying blade servers and virtualization. “It’s my job to run the IT department efficiently and effectively. But it’s as much about cost savings from reduced power usage and reduced cooling in the data center as it is about being green. They go hand in hand.”)

Tips on Going Green With IT
1. Purchase more energy-efficient products. Notebook computers consume less power than desktop computers, while thin-client computing uses even less energy. To purchase the greenest products possible, shop for technology that features the Energy Star label. Energy Star products meet stringent government guidelines for energy efficiency. For example, the latest Energy Star 4.0 rating requires PC makers to use power supplies that convert 80 percent of the incoming power from the outlet into usable computer power, meaning only 20 percent of the power is wasted.
2. Turn off IT equipment that is not in use. Most schools have some IT equipment, such as servers, printers or disk storage, that are on but are abandoned and no longer in use. Find them and unplug them. Schools should also turn off their computers, monitors and printers at night.
Use the power-management settings that put computers, printers and other equipment into sleep mode.
3. Besides using blade servers and virtualization, schools can do the following to further green their data center:
- Upgrade to new servers to consolidate. Schools can consolidate servers by replacing their old, single-processor servers with new servers that have multicore processors, which are more powerful and more energy-efficient, according to The Green Grid, a technology consortium aimed at producing more energy-efficient data centers.
- Redesign your data center. IT departments can redesign their data centers to improve air flow and reduce the amount of power used to cool the servers. For example, reposition or unblock air vents, and reposition servers to prevent cold air and hot air from mixing.
