Greenpeace’s Green Electronics Survey #3

Friday, January 7th, 2011

Greenpeace’s latest Green Electronics Survey reveals that 18 companies participated and that there has been a “general improvement in green features” since the 2008 and 2009 surveys. Notebooks, desktops, netbooks, smartphones, mobile phones, monitors and TVs are assessed against the following criteria:

  • The use of hazardous chemical substances (e.g. PVC, BFRs, phthalates, etc.)
  • Power consumption by the products (benchmarked against the Energy Star standard)
  • Product lifecycle (including use of recycled plastic, take-back programmes, etc.)
  • Innovation and marketing (data about the manufacturing footprint, consumer information, etc.).

In desktops, HP Compaq’s 6005 Pro Ultra-slim came out tops while in smartphones the Sony-Ericsson Aspen (M1) beat out Nokia’s N8-00. Once again Apple declined to participate.

One wonders how many buying decisions are influenced by such a survey….?

Power Options implemented on all IT Windows XP domain workstations.

Thursday, May 28th, 2009

We implemented GPO policy scripts on all IT Windows XP workstations that are part of the STB domain.

The script implements the following settings:
1. Monitor time out after 30 minutes if running on AC Power.
2. Disk time out after 60 minutes if running on AC Power. The disks are completely stopped.
3. System Standby after 120 minutes if running on AC Power.

A further implementation will be to Hibernate after 180 minutes if running on AC Power.

The current script will not change Power Schemes on any Vista or later Operating Systems. For Windows Vista and later Operating Systems, we will implement GPO policy templates. This will be implemented at a later stage.

Activating Power Management on PCs saves money

Thursday, February 5th, 2009

Gartner has published an article that shows that by simply activating power management on PCs, an organisation of 2500 PCs can save 43% of the power consumed by those PCs (433 MWh), which translates to an annual saving of about R240 000 in South African terms. Furthermore, planned Eskom tariff increases will escalate these savings rapidly. (more…)

Microsoft server power management

Thursday, December 18th, 2008

Microsoft has just published an excellent paper for server system administrators entitled Power in, dollars out: How to stem the flow in the data center. It gives a succinct overview of power management considerations on Windows servers and explains how energy-efficient data centres can be implemented.

Shutting down computer labs to save electricity

Thursday, November 27th, 2008

The computer lab in the Faculty of Science, NARGA, has 4 classrooms and 2 open areas containing a total of 310 computers. Of the 6 rooms, 4 are available 24 hours a day. Obviously not all the computers are in use all of the time. We have implemented an auto-shutdown policy that applies in the event that a computer becomes idle after hours. This policy has been active since the beginning of 2008. (more…)

Activate PC power management to save energy

Wednesday, November 26th, 2008

Most newish PCs and all notebooks/laptops have Power Management settings that enable you to minimise the machine’s power consumption, especially for the times when you are not using it. It is possible to save 10% of its power requirement per day through implementing these simple settings which progressively switch off components such as the screen, hard drives, processor, etc. Information Technology has created a help document (pdf) to guide you through setting power management on your PC for Windows XP and Vista. If you would rather want a technician to talk you through the procedure, contact the IT Helpline at (021-808)4367 or ithelp at sun.ac.za.

And of course it should be standard practice to switch off the PC (at the wall socket) when you leave work and over weekends. Also note that screensavers use electricity unnecessarily; rather set your screen to switch off.

Bespaar krag deur die bestuur van werkstasies

Wednesday, November 26th, 2008

IT is besig om ‘n ondersoek te doen, oor hoe krag bespaar kan word, deur die bestuur van werkstasies. Daar word gekyk na die afskakel van werkstasies wanneer dit nie gebruik word nie, asook die afskakel van monitors indien die werkstasie nie gebruik word nie. (more…)
