1. A data center system, comprising: a plurality of data centers configured to receive power from a plurality of power sources, at least one power source comprising a renewable power source that provides power to a first data center of the plurality of data centers; a management system configured to manage execution of a plurality of computational tasks, an individual computational task from the plurality of computational tasks having multiple data components associated therewith, wherein the management system is further configured to: monitor power capacities at the plurality of power sources to detect a current or future instance when a power capacity provided by the renewable power source to the first data center is deficient, wherein, in the current or future instance, the first data center has processed at least some of the multiple data components of the individual computational task and other data components of the individual computational task remain unprocessed, and transfer at least some of the other data components of the individual computational task that remain unprocessed from the first data center that receives power from the renewable power source with deficient power capacity to a second data center that receives power from a second power source with adequate power capacity; and a processor configured to execute at least the management system.
