HP believes that they, along with their customers and power utilities, share responsibility for the energy used by HP products. From the computer chip to the data center, HP constantly looks for ways to improve product energy efficiency and work to educate customers about the effects of their power consumption.

HP Servers
Although fewer servers are sold than other major IT product categories, servers require relatively large amounts of electricity and run continuously, so efficiency improvements in this area are particularly important.

• HP server virtualization and consolidation technologies produce significant savings in cost, energy, GHG emissions and materials use. Virtualization consolidates several workloads on one physical server. Consolidation collapses several servers into a more compact space. Combined, both technologies result in a need for fewer but more efficient servers. At HP, this technology reduced server power consumption from 5 million kWh to 1.8 million kWh in one application alone.
• HP ProLiant and Integrity Blade Servers and c-Class BladeSystem enclosures with embedded thermal logic (launched in 2006) reduce energy consumption by 33% compared with conventional rack-mounted servers. These servers save energy through innovative power management, monitoring and cooling technologies.
• HP’s new and enhanced disk storage systems and tape drives help customers reduce storage power and cooling costs by as much as 50%. 
• SURVEYOR is an easy-to-use software utility from HP that enables customers to measure, manage and reduce their network's energy consumption, saving money and lowering the total cost of ownership. 
• HP's ProLiant 360 G5 server uses 28% less energy than its G4 predecessor, while delivering three times more processing power.

HP Desktops/Workstations
The configurability of desktop and workstation PCs presents significant design challenges to ensure that basic configurations are energy efficient and also allow for the power needed to drive “fully loaded” configurations. HP design engineers balance these requirements to provide customers with both energy efficiency and performance. 

• The HP rp5700 Business Desktop PC, launched in June 2007, is the first product in the industry to receive a gold rating from the Electronic Products Environmental Assessment Tool (EPEAT). Configured for maximum energy efficiency and paired with an HP flat panel monitor, the HP rp5700 Business Desktop PC may save customers as much as 80% in power consumption compared with previous-generation systems using cathode ray tube (CRT) monitors (view case study). 
• HP power management features on new HP 5000 and HP 7000 series Desktop PCs can save up to 481 kWh or about 240 kg of CO2e per year. Upgrading to 24 PCs with these features reduces about the same amount of CO2e emissions as removing a car from the road. 
• HP business desktops were the first in the industry to meet the recently announced ENERGY STAR requirements—months before the new guidelines took effect. 
• All HP workstations released after October 2007 meet the new ENERGY STAR requirements, with standard 80% efficient power supplies, compared with 70% efficiency in prior HP models. 
• HP thin clients use less energy than standard PCs, offering up to 80% savings in power usage.
