Zero-carbon Cloud (and RIVER)

Zero-carbon cloud is exploring a new approach to computing that leverages recent advances in information technology (cloud computing, data center automation, system-focused analytics, etc.), and the advance of renewable energy generation to create truly "green" computing.  The goal is zero incremental carbon emissions.  A key aspect of this approach is the use of "stranded power", that is uneconomic due to geographic and temporal mismatching, and delivery of volatile computing services.  The RIVER system is a flexible NSF-funded testbed for exploring volatility, power, energy, variability, and reliability.

Our new CRISP2 collaboration featured on CS Department Web 9/2018 News: The Zero-carbon Cloud project has just received funding from the NSF CRISP 2.0 program! (details here ). These efforts will explore market, bilateral information sharing, optimization, and computing systems techniques ot reduce the carbon footprint of cloud computing and increase renewable power absorption by the power grid.
