This complements HP’s goal to reduce energy consumption and the resulting greenhouse gas emissions from HP-owned and HP-leased facilities worldwide to 16 percent below 2005 levels by 2010.
To reduce its carbon footprint, HP is relying on diversified renewable energy resources, improving energy efficiency and placing a strong emphasis on energy reduction and optimization at a number of its facilities around the world.
In 2007, HP successfully met its goal to increase renewable energy purchases by more than 350 percent and purchased 61.4 million kilowatt hours (kwh) of renewable energy and renewable energy credits in the United States.
“HP is investing in technologies that bring us closer to operating in a sustainable IT ecosystem,” said John Frey, senior sustainability executive, HP. “We are supporting renewable energy programs for our own operational efficiency, harnessing research to demonstrate environmental leadership and offering products that support customer concerns about rising energy costs.”
Harnessing solar and wind power
HP recently completed a 1.1-megawatt, 6,256 solar panel system at its facility in San Diego. This is one of the largest solar power installations in the County of San Diego and is projected to save the company $750,000 during the next 15 years while providing more than 10 percent of the facility’s power. Further, the system will reduce carbon dioxide emissions by more than 60 million pounds over the next 30 years. This is equivalent to providing electricity to 3,800 homes or removing more than 5,250 cars from the road over this time period.
SunPower ( http://www.sunpowercorp.com/) installed the system and GE Energy Financial Services, a unit of GE that owns the system under SunPower Access, will provide the electricity under a power purchase agreement.
HP also extended the benefits of solar power to its U.S. employees. To date, more than 600 HP employees and retirees have requested an evaluation of a home system installation, and more than 60 have completed an installation or are under contract to install SunPower systems at their homes.
HP elected to participate in Austin’s Green Choice program, to procure almost 19.9 million kwh of wind energy from wind farms in western Texas for two of its Austin data centers, which represents nearly 20 percent of the annual energy used by the two centers. Additionally, the facilities are using the HP Dynamic Smart Cooling (DSC) system, which enables real-time changes to air conditioners, fans, vents and computing equipment help reduce carbon dioxide emissions and reduce energy costs.
HP DSC typically yields energy savings of 20 to 40 percent over legacy HP data centers. HP’s Austin data centers are on track to achieve energy cost savings of more than $100,000 annually based on the integration of HP DSC technology.
HP consolidated three of its facilities in Melbourne, Australia, with sustainability in mind. The new facility design included orienting the building to strategically reduce energy consumption associated with heating and cooling and using energy-efficient lighting. As a result, HP expects to reduce energy consumption and carbon emissions by 70 percent.
Sustainable IT ecosystem
HP is leveraging renewable and non-renewable resources to effectively and efficiently manage a limited supply of available energy. The use of various sources of power throughout its operations will support the development of HP’s micro-grid for power and cooling distribution in the data center facility, which ensures efficiency, manageability and regulatory requirements while meeting service level agreements.
HP Labs, the company’s central research arm, has initiated research that uses nanowire photonics to potentially increase the efficiency of solar cells to more than 20 percent. This development allows solar cells to operate on a level of those used in expensive deep-space applications, while being manufactured at much lower costs, like those used in pocket calculators or to recharge portable devices.
Nanowire photonics may be integrated with a greater selection of conductor materials, allowing for low-cost options. In the future, nanowire photonics may optimize renewable energy throughout the IT industry and other business sectors.
Taking steps to reduce the energy required for manufacturing and
distributing products, HP plans to reduce the energy consumption of its
volume desktop and notebook PC families by 25 percent, relative to 2005.
