During June 2007, Google and Intel initiated the Climate Savers Computing Initiative, with a number of top technology companies, including HP, IBM and Oracle, working hand-in-hand with organisations such as the Environmental Protection Agency (EPA) to reduce greenhouse gas emissions by making hardware more energy-efficient.

Paul Otellini, Intel chief executive officer, said the company has also joined the IT industry's Green Grid Alliance, aimed at increasing the energy efficiency of data centres.
