Disclosed figures

nothing disclosed by 2 records

Power, water, jobs and tax, summed only where a data center disclosed the figure; what each facility is for; how each is cooled. Nothing here is estimated.

Power, water, jobs and tax

Figure	Disclosed total	Not disclosed
Power	Not disclosed	2	Not disclosed by any of the 2 records
Water, stated per day	Not disclosed	2	Not disclosed by any of the 2 records
Water, stated per year	Not disclosed	2	Not disclosed by any of the 2 records
Permanent jobs	Not disclosed	2	Not disclosed by any of the 2 records
Tax each year	Not disclosed	2	Not disclosed by any of the 2 records

Summed only where a record disclosed the figure; a record with no figure adds nothing and is counted as not disclosed. Water is summed per day and per year separately, as the sources stated it, and never converted. A tax claim given as a range is summed at both ends.

A record that lists several uses counts once under each. Each cell is the sum over the records with that use, disclosed rows only.

Third party figures on the same metrics

Numbers from outside sources on the same metric and place. A figure a project disclosed about itself is in the sums above, not here. Where several sources give the same figure for the same place and year, it is one row with every source behind it (22 sources on 19 rows).
