Even as cloud computing offers a more environmentally friendly alternative to on-site IT solutions, Greenpeace believes that cloud computing vendors have the opportunity to alter the entire IT industry's effect on climate change. The organization believes that cloud computing vendors must seek energy providers that use renewable energy rather than coal.

Greenpeace did praise major vendors after they claimed that they consider renewable energy a consideration when selecting a site for a data center. However, as it stands, major vendors like Microsoft and Google operate high-volume data centers that use fewer than 4 percent renewable energy.

"We are calling on IT industry giants to put their might behind government policies that give priority grid access for renewable sources like wind and solar energy," Greenpeace said in a statement. "IT companies should also support economy-wide climate and energy policies around the world that peak climate emissions by 2015."

"The great innovators of the digital age can and should be leaders in promoting an energy revolution," the company added.

IBM senior fellow John Lamb told RedmondMag.com that green IT must be a primary concern of cloud computing vendors moving forward. Aside from the environmental implications, he believes it will save vendors money to virtualize most processes. ADNFCR-2553-ID-19698096-ADNFCR
