Taoiseach: No moratorium on data centres but they must source own backup energy

'[W]e can't say no to all data centres,' Micheál Martin said, speaking in Tokyo on his visit to Japan. 

There can be no moratorium on the building of data centres but tech firms will be required to prove they can produce their own energy if needed, the Taoiseach has said.

Michéal Martin also said consideration must be given to companies which have been in Ireland for some time and want to expand with data centres.
