Hewlett Packard announced that it has completed a 1.1-megawatt solar-electric power system on the roof of its printing technology research and development facility in San Diego.
The solar system was installed by SunPower Corp. It is expected to reduce more than 60 million pounds of CO2 emissions over the next 30 years; equivalent to providing electricity to 3,800 homes or removing more than 5,200 cars off the road.
GE Energy Financial Services owns the solar system and HP will buy electricity from the company under a power purchase agreement program. HP will own the renewable energy credits and environmental benefits associated with the system, which it may retire or sell.
In September, HP announced it has collected emissions data associated with its largest suppliers, which represents more than 80 percent of the company’s costs for materials, manufacturing and assembly of its products worldwide.
In January, HP joined the Carbon Disclosure Project’s Supply Chain Leadership Collaboration. That same month the company also published new guidelines designed to help multinational companies achieve sustainability throughout their supply lines.
In April, HP released a list of its largest suppliers, representing more than 95 percent of the company’s procurement expenditures for materials, manufacturing and assembly of its products worldwide. HP’s hope was that the increased visibility would change supplier labor, health and safety, environmental and ethics practices, and that other companies would follow its lead.
