FOCUS ENERGY
MORE DATA ON HOW TO CUT YOUR ENERGY USE
The UK Department for Energy and Climate Change is reported as saying: “Data centers are significant users of energy, they are responsible for 3% of electricity use in the UK and this is expected to double by 2020.” Do something about it before they do
ENERGY LOGIC: Reducing data center energy consumption Creating savings that cascade across systems
Emerson Network Power modelled energy consumption for a typical 5,000-square foot data center and analyzed how energy is used within the facility. Energy use was categorized as either “demand side” or “supply side.” Demand-side systems are the servers, storage, communications and other IT systems that support the business. Supply-side systems exist to support the demand side.

REDUCING DATA CENTER ENERGY CONSUMPTION. A summary of strategies used by CERN, the world’s largest physics laboratory
To deploy massive new computing resources without exceeding limits of its 35-year- old data center, CERN is taking a comprehensive view of energy efficiency. This paper outlines CERN’s key moves to the latest Intel Xeon processors that are helping increase performance per Watt by a factor of five.

IMPLEMENTING ENERGY EFFICIENT DATA CENTERS
Many discussions regarding electrical power consumption use the term “efficiency”. While the underlying meaning of terms like “improving efficiency” are well understood, the technical use of the term “efficiency” for quantitative assessment of data centers leads to confusion. Discussions are much clearer when electrical power consumption (kW) is the metric used, rather than efficiency metrics.

ENERGY EFFICIENCY IN THE DATA CENTER
Exploring the inherent
compatibility of green initiatives and corporate profitability. In 2006, data centers consumed about 60 billion kilowatt- hours (kWh) of electricity, equaling roughly 1.5% of total U.S. electricity consumption. Estimates project that by 2011, this figure will double—if current trends in design and operation continue
