The workshop aims to bring together researchers, practitioners, system administrators, software developers, and others interested in the latest advances of energy efficient clouds. Special focus will be on novel methods and tools to support software developers aiming to optimise energy efficiency and minimise the carbon footprint resulting from designing, developing, deploying and running software at the different layers of the Cloud computing stack. We call on to researchers and professionals to present their latest work on addressing such related challenges and to share their experiences and best practices in the deployment of such systems.
