Shift Workload

Execute tasks when the grid is powered by renewable energy

Carbon Aware Computing (2022)


The basic idea behind the time shifting approach is moving the computing load into a point in time when the power grid has a maximum of renewable energy. This will result in a lower emission of CO2 of a computing task.

In addition to energy and hardware efficiency, carbon efficiency is one of the most important principles of green software development, like the Energiewende. Energy is used when it is available from renewables.


We shift the energy demand to a point in time when the carbon intensity of the grid is lower. To do this we need forecast data and software libraries to calculate the appropriate execution window.
