Here is the essential finding:
“In a world-first model of internet power consumption, University of Melbourne researchers have been able to identify the major contributors to Internet power consumption as the take-up of broadband services grows in the coming years.
“It has now become clear that the exponential growth of the Internet is not sustainable, “said Dr Hinton.
The result indicates that, even with the improvements in energy efficiency of electronics, the power consumption of the Internet will increase from 0.5% of today’s national electricity consumption to 1% by around 2020.
Dr Hinton says the growth of the Internet, IT broadband telecommunications will provide a wide range of new products and services.
New home services include Video on Demand, web based real-time gaming, social networking, peer-to-peer networking and more. For the business community, new services may include video conferencing, outsourcing and tele-working.
“To support these new high-bandwidth services, the capacity of the Internet will need to be significantly increased. If Internet capacity is increased, the energy consumption, and consequently the carbon footprint of the Internet will also increase.”
