Amazon said Monday that it will spend $20 billion on two data center complexes in Pennsylvania, including one it is building alongside a nuclear power plant that has drawn federal scrutiny over an arrangement to essentially plug right into the power plant.

Amazon says approximately 1,250 new "high-paying, high tech" jobs will be created by the $20-billion investment that includes a Falls Township campus.

As data center demand soars, Amazon expands the use of wastewater to cool its U.S. data centers and curb its use of drinking water.
