I do not believe this information is collected centrally. The Departments of Enterprise, Trade and Employment and the Environment, Climate and Communications do not have it and I do not believe any other entity knows exactly how many data centres there are, where they are, what their energy usage is and what the demand is. I had assumed the CRU would have that information because data centres currently account for 15% of our energy use and will, potentially, account for up to 30% of energy use in the next number of years. It is astonishing that no entity has oversight and visibility of exactly what data centres are using.
