Show Notes

As a country, we are spending more to get data centers up and running than we spent to build the entire interstate highway system. (Yes, that’s inflation-adjusted.) With tech companies spending hundreds of billions of dollars on AI, data centers have kind of become the thing in the US economy. 

But along with that growth have come a lot of questions. Like where is all the electricity to run these data centers supposed to come from? And how much are residential customers’ electric bills increasing as a result?

On today’s episode, we go to Ohio to trace one electric bill back to its source, to see what exactly is causing the big price increases people are seeing. We take a tour of a data center hot spot, and get to the bottom of how prices are set from inside the power company.
