In 2011 the total UK datacentre power was estimated[1] as 6.4GW with 6.7%
growth P/A. Assume half that's cooling, so relatively smooth inductive
load, and the other 3.2GW is consumed during 4ms out of every 20ms cycle,
which makes it equivalent to 16GW peak, or 2/3 of the UK's average base
load ... still insignificant Harry?

Most of it goes on cooling/ventilation not DC driven cevices.
I was reading only lately that data centres are being moved to colder
climates than ours to get round the energy consumption /cost problem.
Finland & Canada being favourite.
