"コンピュータに「エコ志向」の萌芽 523人に聞くITの消費電力／熱問題", 日経 BP IT pro, 2006/09/07
　http://itpro.nikkeibp.co.jp/article/OPINION/20060904/247059/
　"プロセサの性能向上に伴い，コンピュータの消費電力や発熱の問題が急浮上している。ITproの
　 姉妹サイト「Enterprise Platoform」では8月，IT関係者がこの問題についてどう捉えているか調査。
　 523人から回答が得られた。全体として消費電力や発熱に対する意識はまだ低いものの，関心は
　 着実に高まっているようだ。調査結果のポイントを紹介しよう。"

"光ファイバ照明システム--これからの主流になるか？", CNET Japan, 2006/09/05
　http://japan.cnet.com/news/ent/story/0,2000056022,20223708,00.htm
　"オハイオ州ソロンに本拠をおくFiberstarsは、産業用の照明設備と光ファイバ技術を組み合わせて、
　 従来の蛍光灯や白熱灯よりもはるかにエネルギー消費の少ない室内照明システムを開発した。
　 同システムはメタルハライド高輝度放電（HID）ランプを利用し、70ワットのメタルハライドランプ1個で
　 50ワットの白熱灯8個分の光量を得ることができる。

　 　「このシステムの消費電力は、エネルギー効率が最もよい蛍光灯の約3分の1、平均的な蛍光灯と
　 比べると約4分の1だ」とDavenport氏は語った。さらに光ファイバ照明では、蛍光灯と違って水銀を
　 使用しておらず、熱や紫外線も出さない。"

　http://www.spec.org/specpower/pressrelease.html
　"The non-profit Standard Performance Evaluation Corp. (SPEC) has formed a new committee to develop standard
　 methods and metrics for comparing energy use of server-class computers."
　"The first SPEC energy and performance benchmark is scheduled for release in the first quarter of 2007."

SPEC Power-Performance Committee
　http://www.spec.org/specpower/
　"The SPEC Power-Performance committee has begun development of the first generation SPEC benchmark
　 for evaluating the energy efficiency for server class computers."

　Benchmark Goals
　　System utilization will vary in order to provide multiple usage loads and energy measurement points.
　　　Energy measurements are made at the AC input to the system under test.
　　　The benchmark as initially planned addresses a subset of server workloads.
