Zero-carbon Cloud and the Zero-carbon Compute Project

Zero-carbon cloud (ZCCloud) proposes a new approach to reduce the carbon footprint of the rapidly growing cloud. Specifically hyperscale cloud datacenter networks such as Amazon, Google, Microsoft, Facebook, Apple, Baidu, Alibaba, and more are a growing problem as they are driving the increase of electric power consumption in both developed and developing world. The ZCCloud approach exploits a growing phenomenon called "stranded power", that is uneconomic due to geographic and temporal mismatching, and delivery of volatile computing services. The quantity of stranded power is growing rapidly in Europe, the United States, China, and around the world as renewable generation provides a growing fraction of electrical power, exceeding gigawatts in major power grids. Coordinated datacenter workload scheduling and management matched to advanced grid management has the potential to create carbon-free cloud computing that is essential to the continued growth of cloud computing. Many interesting scheduling, resource management, data center design, distributed systems, power market, and power grid research arise from this radical new approach of "supply-following" cloud computing.

Two Zero-carbon Cloud subprojects now have their own pages:

Several overview articles for Zero-carbon Cloud include a 2019 Overview and 2015 vision paper . Andrew Chien gave a keynote talk at the 2016 ACM PODC Conference outlining interesting new distributed systems problems for sustainable cloud computing approaches such as Zero-carbon cloud. Lancium and Soluna are venture-funded startups building over 1 gigawatt (1,000 megawatts) of Zero-carbon Cloud. ZCCloud builds on a prior effort, the RIVER system that created a flexible NSF-funded testbed for exploring volatility, power, energy, variability, and reliability.
