In a latest report on 'Low-Carbon and Environmental Leadership in ICT Industry, 2010', Gartner and WWF Sweden assess that ICT industries foresee climate change and sustainability as emerging opportunities. The study evaluated green credentials and examined vendors driving initiatives to reduce green-house gases (GHG) contributed by ICT industries. Of the 28 invited by Gartner and WWF, the 19 participating companies included: Accenture, Alcatel-Lucent, BT, CSC, Cisco, Dell, Deutsche Telekom, Ericsson, Fujitsu, HP, IBM, Lenovo, Microsoft, SAP, Sun Microsystems, TCS, Verizon, Wipro and Xerox.

With a focus on the 2 percent of ICT's global CO2 emissions, Fujitsu is focusing on Green ICT throughout the entire product lifecycle —from basic technology research and development, to produce design and operation, and through to operating recycling services. Some of the key innovations and practices from Fujitsu are as follows:

Zero Watt displays and PCs

While an Eco button and automatic brightness controls enable an energy saving of approximately 50%, Fujitsu's technologies for displays have enabled to achieve zero watt power consumption in stand-by mode. In addition to displays, Fujitsu's ESPRIMO E/P990PC series do not consume any power in stand-by mode.

'While zero watt PCs differ from conventional PCs in terms of their power supply unit, motherboard and BIOS, they do not represent an entirely new product. However, we had to completely re-model the BIOS and motherboard to achieve zero-watt power consumption.' says Peter Bush, Head, Zero-Watt Development Team, Fujitsu.

Data center energy savings

Fujitsu's London North Data Center was able to successfully save energy by leveraging Fujitsu's management expertise. For example, a machine room is normally kept at a temperature of about 21 degree Celsius but research revealed that a temperature increase of 1 or 2 degree Celsius would have no effect on machine's performance. Similarly, while humidity should be maintained in the proximity of 50%, studies confirmed a slight increase or decrease in humidity will not cause any problems in machine management. Other measures introduced included the floor layout so that air with different temperatures would not mix. These efforts helped the facility to reduce yearly CO2 emissions significantly.

Server power reductions

PRIMERGY BX 900 blade server is designed for optimum performance per watt and virtualization capabilities resulting in lower power demands and operating costs. Through application of low power components and better cooling efficiency, Fujitsu claims to reduce electricity consumption by 40% compared to rack mount servers. It also in a way has reduced the burden on the air conditioning of the entire data center. PRIMERGY CX 1000 cloud server is optimizing cost drivers of power, heat and space in a similar way.
