Abstract
Disclosed is a method of managing electricity providing in a computers cluster, including: a process of prediction of need of electricity provided by at least one renewable electricity source in the computers cluster, a process of prediction of availability of the electricity provided by the renewable electricity source, including: a step of managing failure risk of the renewable electricity source, by lowering the predicted availability, so as to: increase life expectancy of the renewable electricity source, and/or lower maintenance frequency of the renewable electricity source, a process of scheduling tasks in the computers cluster, based on both the prediction processes.

- wherein:
- in case of need prediction decrease because of workload decrease, said renewable electricity source (1, 2, 3) will be reconfigured so as:

- and/or not running at full speed when running, and preferably wherein:
- in case of need prediction decrease because of workload decrease, said renewable electricity source (1, 2, 3) will be reconfigured so as:
- provide extra electricity to the grid if it accepts it at that time, preferably in a stable way,
- and/or provide extra electricity to backup rechargeable batteries if they are not sufficiently filled,
- or, in case both said grid does not accept and said backup rechargeable batteries are sufficiently filled, said renewable electricity source (1, 2, 3) will be reconfigured so as to automatically fit actual need prediction but not more.
