CO2.Earth is hosted on servers powered directly by the sun. This is hosting without fossil fuels or the need for offsets.
In July 2009, shortly after Michael McGee started using AISO.net web hosting services, he toured the data center in Californai, USA. The photo below shows Michael with the solar panels and data center in the background. Thanks to Phil Nail, AISO's Chief Technology Officer, for taking the photo and lending his sunglasses.
