SECTION 1. STUDY. 
Not later than 180 days after the date of enactment 
of this Act, the Administrator of the Environmental Pro-
tection Agency, through the Energy Star program, shall 
transmit to the Congress the results of a study analyzing 
the rapid growth and energy consumption of computer 
data centers by the Federal Government and private en-
terprise. The study shall include— 
(1) an overview of the growth trends associated 
with data centers and the utilization of servers in 
the Federal Government and private sector; 
(2) analysis of the industry migration to the use 
of energy efficient microchips and servers designed 
to provide energy efficient computing and reduce the 
costs associated with constructing, operating, and 
maintaining large and medium scale data centers; 
(3) analysis of the potential cost savings to the 
Federal Government, large institutional data center 
operators, private enterprise, and consumers avail-
able through the adoption of energy efficient data 
centers and servers; 
(4) analysis of the potential cost savings and 
benefits to the energy supply chain through the 
adoption of energy efficient data centers and servers, 
including reduced demand, enhanced capacity, and 
reduced strain on existing grid infrastructure, and

consideration of secondary benefits, including poten-
tial impact of related advantages associated with 
substantial domestic energy savings; 
(5) analysis of the potential impacts of energy 
efficiency on product performance, including com-
puting functionality, reliability, speed, and features, 
and overall cost; 
(6) analysis of the potential cost savings and 
benefits to the energy supply chain through the use 
of stationary fuel cells for backup power and distrib-
uted generation; 
(7) an overview of current government incen-
tives offered for energy efficient products and serv-
ices and consideration of similar incentives to en-
courage the adoption of energy efficient data centers 
and servers; 
(8) recommendations regarding potential incen-
tives and voluntary programs that could be used to 
advance the adoption of energy efficient data centers 
and computing; and 
(9) a meaningful opportunity for interested 
stakeholders, including affected industry stake-
holders and energy efficiency advocates, to provide 
comments, data, and other information on the scope, 
contents, and conclusions of the study.
