Telstra saves tonnes of energy by turning off screensavers
Telstra has switched off screensavers on around 36,000 computers across the company, reducing the company’s annual energy consumption by an equivalent of around 646 tonnes of CO2 based on conservative estimates.
Telstra’s colourful corporate screensavers were removed from all Windows XP employee laptops and desktop computers and replaced with a black screensaver. This relatively simple step is comparable to removing about 140 cars from Australian roads for a year.
Seven ways to use telecommunications opportunities to save on greenhouse gas emissions:
- Networked demand–side energy management to increase renewable energy use.
- Integrated personalised public transport to your door with a phone call, or ordered online.
- “In-person” high-definition video conferencing in lieu of business travel.
- Presence-based power to turn appliances on or off using wireless presence sensors.
- Real-time freight management with vehicle monitoring via wireless broadband to fill empty vehicles.
- Remote power management for appliances not in use or on “stand-by”, via a broadband enabled sensors.
- De-centralised business district: teleworking.
Telstra’s head of Public Policy & Communications Dr Phil Burgess said reducing the environmental impact of Telstra’s operations is an efficient use of resources and provides better value for shareholders.
“Telstra has a commitment to provide good stewardship of the environment, first and foremost by conservation. In the lead up to World Environment Day on 5 June, removing screensavers from our computers is a simple initiative, however the financial and environmental benefits are significant,” Dr Burgess said.
Telstra Property Director Mr Vito Chiodo said:
“Previously Telstra’s multi-coloured screensaver was used to share our corporate messages. By replacing this with a black screensaver we are sending a strong environmental message to our staff that we are listening to their suggestions for ways to save energy and that we should take every opportunity, at every level in the organisation, to walk our talk.”
Originally, screensavers were designed to conserve older computer screens that would be damaged by leaving the same areas illuminated for long periods. However modern screens don’t require these measures and over time screensavers have been used predominantly for entertainment and communication.
