Nowadays saving energy is an interdisciplinary key challenge. Green IT deals with saving energy in IT systems, and is rapidly gaining momentum. Hardware manufacturers and designers have ﬁrst considered the problem, in the ﬁeld of IT, but recently software energy efﬁciency gathered the interest of industry and academic research. In this paper we aim at summarizing the available knowledge in Green IT. In particular we: • Introduce a taxonomy of concepts related to energy and IT. • Present recent data on energy consumption trends organized according to the taxonomy. • Present some guidelines to write energy efﬁcient software organized according to the taxonomy. • Underline what is missing and what should be done in future research.
