Ireland: Data Centers Now Consuming More Electricity Than Rural Homes

According to the Irish Times, citing new figures from the Central Statistics Office, data centers used up a greater share of electricity consumption than rural homes in the State last year. The overall share of metered electricity consumed by data centers has almost tripled in just six years, from 5 percent in 2015 to 14 percent last year. By comparison, urban homes accounted for 21 per cent of metered electricity consumed in 2021 compared with 12 percent consumed by rural dwellings. The figure for electricity consumption by data centers last year represents an increase of 32 percent in that year.

Data centers consumed 265 per cent more electricity in the three-month period between October and December 2021 compared with the three months between January and March 2015. Total metered electricity consumption increased by 16 per cent over the six years with data centers accounting for the 70 per cent of the increased consumption over that period. The surge in electricity use by data centers has come under scrutiny due to concerns about the State’s energy supply and the targeted reduction in carbon emissions to tackle climate change. “There should be more discussion and more serious consideration of a moratorium [to block the opening of more data centers in order to reduce emissions],” said Dr Patrick Bresnihan, a geography lecturer at Maynooth University.

Allowing electricity consumption by data centers to continue to increase would make it harder for the Government to push policies where it is asking individuals to reduce consumption at a time “when consumption by data centers is so high and clearly just growing,” said Dr Bresnihan.
