Governments around the world are intensifying scrutiny on the building of data centres over fears that their huge energy usage is putting excessive pressure on national climate targets and electricity grids.
Ireland, Germany, Singapore and China as well as a US county and Amsterdam in the Netherlands have introduced restrictions on new data centres in recent years to comply with more stringent environmental requirements.
The threat to new projects is highest in Ireland, a hotspot for server farms built by cloud computing companies such as Google and Microsoft, because of its low tax rate and easy access to high-capacity subsea cables through which global internet traffic is run.
