The accounting is in: In Oregon there are 111 data centers. The TOTAL number of people employed at data centers is just 2,630, or 0.1% of the labor force. Those 100 data centers consumer 23% of all electricity used in Oregon. Meanwhile, electricity rates skyrocket as more centers are built.

Oregon data centers by the numbers: 111 facilities consume nearly one-quarter of state’s power, according to new report
A first-of-its-kind report details the footprint of the controversial facilities.
