This summer, Arizona Public Service, the state’s largest utility, saw record-breaking demands for energy. APS reported customers had used about 90% of its planned capacity.

So what’s driving the increasing need for electricity?

An analysis of early information found data centers made up half of the growth in energy demand for APS this year. It takes a lot to keep the centers running all day, every day. 

Clark Miller, ASU professor and energy expert, says natural gas is able to supply that kind of power.
