HP aims to cut energy use by a fifth with wind and solar power

Hewlett-Packard has expanded its use of renewable energy as part of its goal to reduce overall global energy consumption 20% by the end of 2010.

HP has signed deals with two renewable energy providers. As part of a power purchase agreement with SunPower, HP will install its first-ever large-scale solar power installation at its San Diego facility.

In addition, a wind power contract with Airtricty will ensure that nearly 90% of HP's energy use in Ireland is renewable, exceeding the company's 2007 target for carbon emission reductions.

"Switching to renewable energy sources such as solar and wind power makes both environmental and business sense," said Pat Tiernan, HP vice-president for social and environmental responsibility.
