Leave it to Iceland to produce what's being billed as the world's only "truly green" public cloud computing offering. GreenQloud offers carbon neutral cloud computing virtual servers and data storage -- infrastructure as a service -- that companies and individuals can rent by the hour. Additionally, the Icelandic company says it only uses renewable and clean energy sources (geothermal and hydropower energy). Founded this year, GreenQloud is now taking registrations for its beta program. As Iceland sits between Europe and North America, GreenQloud hopes to deliver both hosting and storage on both continents from one place.
