よく調べたら、このレポートが以下の記事等の、Googleが 900.000台のサーバを
導入している根拠となっています。

"Report: Google Uses About 900,000 Servers"

"A sneak peek into Google’s servers and energy efficiency"

  "A report from data center energy expert Jonathan Koomey, published
   on Monday morning, gave a rare glimpse into some educated estimates
   for how many servers and how much electricity Google uses, and how
   energy-efficient those custom servers are."

確かに、

"Table 4: Educated guesswork about electricity used by Google's servers"
 (Page 23)

で、2000年、2005年、2010年の各種情報 (サーバ台数、各種機器の BkWh等) を
一覧にしています。沢山の注釈付きですが。
