Question to the Department for Science, Innovation & Technology:

To ask His Majesty's Government what the total kilowatt-hours and average power usage effectiveness have been for each year since 2019/20 of (1) the government server rooms, and (2) their industry suppliers in providing the equivalent, including via public cloud.

No central assessment has been made of what the total kilowatt-hours and average power usage effectiveness have been for each year since 2019/20 of (1) the government server rooms, and (2) their industry suppliers in providing the equivalent, including via public cloud. Whilst we would expect individual organisations to have an understanding of the power usage costs associated with the running of their on-premise services this is not information that is recorded centrally.
