Like Mel Gibson Urging People to Support Israel

H.R.5646 : To study and promote the use of energy efficient computer servers in the United States.
Sponsor: Rep Rogers, Mike (MI) [MI-8] (introduced 6/20/2006)
Cosponsors (None)
Committees: House Energy and Commerce; Senate Energy and Natural Resources House Reports: 109-538
Latest Major Action: 8/4/2006 Referred to Senate committee.
Status: Read twice and referred to the Committee on Energy and Natural Resources.

In a nutshell, any company who needs Congress to tell them to buy energy efficient servers a) isn't going to find out about Congress' urging anyway b) probably deserves to go out of business.
