Products, services and software use
HP is committed to providing products, services and software to help customers improve their energy efficiency and meet their sustainability objectives. We continue innovating, as we have since 1992 when we launched our Design for Environment program, to drive energy efficiency, reduce the carbon intensity of HP products and help customers to save energy. Further progress is essential, since greenhouse gas (GHG) emissions from IT equipment are growing at about 6 percent a year in absolute terms1 due to the growth in IT usage. We are committed to reduce the energy consumption of our products by 40 percent by 2011, from a 2005 baseline.
We take a holistic approach, from the desktop to the data center, including products, services and software. Each PC uses relatively modest amounts of energy – typically less than 50 watts when in “idle” mode. However, saving relatively small amounts of energy on each PC, server and printer results in large emissions reductions because of the high numbers of products in use – In total, PCs (including monitors) and printers are responsible for almost twice as much GHG emissions as data centers.2
In 2009 we extended the Carbon Footprint Calculator for printing to our personal computing products. The web-based HP Carbon Footprint Calculator helps customers to reduce the environmental impact—and costs—of computing and printing. (See case study.) It provides an estimate of how power-saving technologies and more efficient features can lower customers’ energy use, and carbon footprint. The tool covers printers, desktop PCs, notebooks, workstations, thin client3 computers, displays and point of sales equipment. (See case study.) We also launched Power To Change, a campaign that encourages personal computer users to change behavior to make the most of our low-energy features.
We help customers adopt more sustainable practices with products such as Halo Solutions (see case study) and SkyRoom (see case study), reducing energy costs and emissions by avoiding travel, while digital printing reduces energy and paper use in conventional printing. (See Enabling a low-carbon economy.)
Data center energy use reduction is important because each center uses substantial amounts of energy and the number of data centers is increasing rapidly—electricity consumption of U.S. data centers is expected to double between 2006 and 2011.1 Reducing data center power consumption starts with more energy-efficient IT infrastructure and includes technology initiatives such as virtualization and automation. Further advances are achieved through optimization of data center planning, energy efficient data center designs and integration of facilities with IT. HP products and services are available in all these areas.
Notebook and desktop PCs and workstations
By 2009, the average energy consumption of our highest-volume desktop and notebook PCs had already decreased by 41 percent since 2005.
We continue working to increase energy efficiency, and at the end of 2009 we had over 120 HP PC product families with configurations that meet the new ENERGY STAR® 5.0 specifications, which include a requirement for 85 percent energy efficient internal power supplies. This includes HP thin client computers, making HP the first company to qualify products in this new category.
HP Power Assistant,4 available on desktop and notebook products, helps users to conserve power. And specifically in notebooks, it also stretches battery run time. On the network level, HP Power Assistant measures, records and reports platform energy use to provide IT departments the information needed to save money and energy.
In 2009, we estimate that by using HP Power Management Technology, customers reduced GHG emissions by 460,000 tonnes of carbon dioxide equivalent (CO2e), the equivalent of taking 88,000 cars off the road for one year. Our goal is to save customers 1 billion kilowatt-hours (kWh) of electricity by 2011 through improved energy consumption of our notebooks, PCs and workstations, relative to 2008.
Imaging and printing
HP enables customers to make smart printing choices by providing products, services and tools to save energy and paper. Saving paper is an important way to reduce climate impact because some estimates suggest that making 1 tonne of paper results in 1.5 tonnes of CO2e emissions. This is the major contributor to GHG emissions from the printing process. (See also Enabling a low-carbon economy.)
In 2009, HP shipped more than 24 million ENERGY STAR qualified printers—more than any other vendor. All new 2009 inkjet and LaserJet printer families have ENERGY STAR qualified offerings. The HP Officejet Pro 8500 Premier All-in-One uses only half the energy of comparative laser printers. (See case study.)
We introduced HP Auto-Off technology in 2009, which saves energy by putting the printer into a mode that uses less than one watt of power. It will help customers improve energy efficiency in personal desktop LaserJet printers by three times compared with normal sleep mode. HP will configure printers to power down, but customers can set their own power-down times.
HP Auto-Off works in concert with Instant-on Technology, found in HP LaserJet printers, which helped customers avoid 1.3 million tonnes of CO2e emissions in 2009 (see case study). This feature enables a printer to warm up in a matter of seconds from the sleep mode or even off mode.
HP’s Eco Solutions printing practice includes products and services such as Managed Print Services and HP Web Jetadmin (see case studies) that help large organizations reduce their environmental impact by improving printing efficiency.
Energy use for data centers is high and growing, driven partly by an information explosion (see essay)—it is estimated that the world digitized about 186 exabytes of data in 2007 (one exabyte is a billion gigabytes) and that will grow to nearly 1,000 exabytes in 2020.
Improving the energy efficiency of data centers, including our own is therefore a priority for HP. We collaborate and consult with government authorities and industry bodies to help improve IT industry practices relating to data center energy use. This includes being part of the team that created the EU Code of Conduct and data center Code of Conduct best practice, and working with the United States Green Building Council to develop standards for better environmental design for data centers. We are also participating in a U.S. Department of Energy steering committee developing a framework to certify data center energy specialists.
We deliver a wide range of solutions, from energy-efficient servers, storage and networking devices, through automation, to data center consulting, design and management. In 2009, we introduced HP ProLiant Generation 6 (G6) servers, delivering twice the performance at half the power of the HP servers they replace. HP ProLiant DL 360 and DL380 G6 servers were the first in the industry to meet the ENERGY STAR for Computer Servers 1.0 guidelines released in May 2009. (See case study.) Several ProCurve network switches have been certified to Miercom’s Green Standard. One of these switches measured as up to 45 percent more efficient than the industry average. (See case study.)
