Energies Special Issue Information ( https://www.mdpi.com/journal/energies/special_issues/cloud_computing_energy_... ) Dear Colleagues, In the current digital era, computing is prevalent, and the level of penetration of computing in society, industry, economy, science, and engineering will only increase. Therefore, the energy involved in computing—which was not considered a big issue in the past—is becoming a grand technological challenge. The proportion of total energy consumption represented by ICT is rapidly increasing. By 2030, it is predicted to consume around 50% of all the generated electricity, according to some prognoses. This situation is not sustainable, and extraordinary efforts are needed to increase energy efficiency in ICT. Cloud computing systems have demonstrated exponential growth over the last decade and quickly become the dominant computing infrastructure. By the end of 2020, two-thirds of enterprise infrastructure will be cloud-based; additionally, 82% of the workload will reside in the cloud (https://techjury.net/stats-about/cloud-computing/). Therefore, any improvements in the energy efficiency of cloud systems will also improve the global energy efficiency of computing. This Special Issue invites submissions addressing all aspects of energy efficiency in cloud computing systems at all levels. Manuscripts reporting accurate application-level power and energy predictive models, and energy measurement methods and tools are particularly welcome. Methods on the optimization of multiple objectives are also welcome but must include energy consumption as one of the primary objectives.
