Computers and other technology equipment are responsible for a growing amount of energy use. For example, in 2000 the U.S. Department of Commerce estimated that office and telecom equipment were estimated to account for almost 10% of U.S. commercial electricity consumption, with PCs, workstations, servers, networks and printers responsible for about two-thirds (or 6%) of that¹. Due to the rapid growth of IT worldwide, energy efficiency is important to conserving energy and addressing climate change. HP innovation has focused for years on reducing energy consumed by our products, saving customers money and reducing carbon dioxide (CO₂) emissions that contribute to climate change. Because most electricity is produced by power plants burning fossil fuels, reducing energy consumption enables our customers not only to save money on their utility bills but also to play a part in addressing climate change.

Product energy efficiency complements energy reduction in our operations. We also extend our reach by working with organizations such as WWF (World Wildlife Fund) and collaboration with international industry groups and governments to develop energy efficiency metrics and standards.

HP began addressing energy efficiency in the design phase of our products in 1992, with the launch of our Design for Environment (DfE) program. In 1996, HP Labs established a Power and Cooling Team and we now hold over 1,000 patents in this area.

Our product energy strategy is to deliver energy-efficient products and services through innovative design, effective partnerships, and advanced research by HP Labs. Our objective is to offer products that can save customers energy and money and that minimize environmental impact.

HP has set a goal to reduce the combined energy consumption of our operations and products by 20% by 2010. We also set energy efficiency goals for several product segments (see Goals for further explanation). Achieving these goals is part of our strategy to be an industry leader in energy efficiency.

	Innovation from the chip to the data center

We offer energy-saving innovations across the spectrum of our products and services – such as using energy-efficient computer chips developed by our suppliers in the semiconductor industry, creating servers with breakthrough technology and developing industry-leading services for data centers.

Energy savings can result from small improvements multiplied across a large number of products, as well as from more sizable advances in specific products and services.

For example, HP servers launched in 2006 take advantage of partner innovations by using processors that can reduce processor power consumption by 24% when utilization is low. In 2007, we have redesigned our HP Deskjet printers to reduce their off-mode power consumption to less than 1W. This will enable customers to save as much as 50% on their energy bill for printing and associated CO₂ emissions that would otherwise result from the generation of electricity saved.

Our latest PCs and workstations are more efficient than the HP products they replace. For example, our Blade PC incorporates low-voltage processors that are 10 times more efficient than those in a typical desktop PC². In addition, we now offer power supplies on several commercial PCs that are on average 15% more energy efficient than previous power supplies.

Our C-Class blade servers, launched in 2006, use only two-thirds the power of conventional blade servers due to innovative Thermal Logic power and cooling technologies such as Dynamic Power Saver, which monitors power consumption data to intelligently control power supplies, and Active Cool fans, which were inspired by model jet aircraft engines.

Enterprises with data centers can save even more energy by using HP's industry-leading Dynamic Smart Cooling (DSC) service. Cooling can represent 60% to 70% of the total power needs of a data center. DSC can reduce energy consumption related to cooling by as much as 40% for a small center. For larger data centers, the power savings can represent up to 10,000 tonnes of CO₂ avoided per year (see case study).

For details of specific developments in 2006, see the Performance page.
