Data centre protests spread across Europe, with Dublin crowds in the thousands by some counts

Dublin march and crowd figures

On Saturday, 7 November 2026, demonstrators filled Dublin city centre for what organisers presented as Ireland's first national protest against data centres. Friends of the Earth Ireland ran the event as one element of a continent-wide initiative, and marchers set off from the Garden of Remembrance on Parnell Square toward Leinster House. Crowd figures differ by outlet: the Irish Times counted hundreds, TheJournal.ie and RTE described thousands, and a Bloomberg report attributed a figure of 2,000 to RTE. Politicians from the Social Democrats, the Greens and People Before Profit attended, as did Sinn Féin TD Eoin Ó Broin and Dublin MEP Lynn Boylan. Local campaign groups from Kildare, Waterford, Wicklow and Clare joined the crowd.

Electricity bills at the centre of the argument

Rosi Leonard, data centre campaign lead at Friends of the Earth Ireland, said ordinary households are carrying the cost of the country's rapid data centre growth. Central Statistics Office figures show wholesale electricity prices almost doubled over the past year, and data centres now account for 23% of Ireland's electricity consumption. Leonard pointed to a recent report as the basis for her claim.

“A recent report shows that the electricity consumption by big data centres may be resulting in higher energy costs for households.”

That report puts the possible extra cost to a typical household at €360 over 2015 to 2023, linked to the grid impact of data centres. Demonstrators want an immediate moratorium on new facilities until their full impact has been properly assessed. They also argue that a condition requiring new data centres to source 80% of their electricity from renewables does not go far enough.

Government position and local planning fights

The Government published a report in June, commissioned at a cost of €100,000, which claims that data centres have added €22 billion to the economy since 2010, created 17,000 jobs and generated €2.8 billion in tax. Minister for Enterprise Peter Burke described data centre expansion as a strategic opportunity for the Irish economy. Protesters reject those economic arguments, pointing out that Ireland already has more than 100 data centres and that they create few jobs. Planning permission was refused in October for a Kilmeaden development on the grounds of a former cheese plant, a scheme that would have combined three data centres with a solar farm and gas turbines, after local objections. Residents near Echelon's DUB10 site in Clondalkin have reported ongoing noise and broken sleep, and the Environmental Protection Agency is investigating. Residents in Naas and Jigginstown, County Kildare, also oppose large schemes, and an appeal is pending against a €1 billion project in Rochfortbridge, County Westmeath.

Protests across Europe and the UK

Bloomberg reported that about 1,300 people gathered in Helsinki on the same day.

In England, Slough has the largest concentration of data centres in Europe, and residents describe a constant low hum from industrial cooling fans that runs into the early hours. Dr Ambily Banerjee, a health equity expert with 30 years in STEM, organises Slough Against Data Centres, a resident-led group active since July 2026. In Leeds, Lianne Marie Mease runs the No Leeds Data Centre campaign, which has 170 volunteers, while Microsoft is building a £4bn hyperscale AI data centre at the former Skelton Grange power station site, with two more on the horizon. Mease says the campaign has drawn in people who had never joined a protest before.

“I've never seen anything unite politics like hyperscale data centres.”

A poll by the Ada Lovelace Institute found 89 per cent of Britons want some form of AI regulation. The Leeds group is one of 96 other groups across the UK and Europe in the Stop Dirty Data Centres coalition, which organised two days of action on 6 and 7 November to demand a moratorium while governments assess the facilities.
