Yann LeCun (Vice-President, Chief AI Scientist at Meta):

  AI datacenters will be built next to energy production sites that can produce 
  gigawatt-scale, low-cost, low-emission electricity continuously.

  Basically, next to nuclear power plants.

  The advantage is that there is no need for expensive and wasteful
  long-distance distribution infrastructure.

  Note: yes, solar and wind are nice and all, but they require lots of land
  and massive-scale energy storage systems for when there is too little sun
  and/or wind. Neither simple nor cheap.
