Digital Green Earth
In 'From Digital Economy to "Digital GreenEarth"' Yasuhiko ARAKAWA (Director, Institute for Nano Quantum Information Electronics) argues that ICT can create a low greenhouse gas emission economy in Japan by 2050. He predicts that online information requirements will increase 200 times from 2006 to 2025, so the energy use of the technology needs to be reduced. The estimate of a 200 fold increase is probably an underestimate, but even greater efficiency should be possible.
Professor ARAKAWA suggesters:
Boosting energy efficiency of network infrastructure and servers
Energy management in lighting and air conditioning
