What You Pay For

The third thing you live with next to a data center doesn’t show up in a photograph, because it isn’t physical — and it reaches more people than the noise and the air put together. It’s the electric bill.

When a data center lands in your region, the grid has to grow to feed it — new substations, new transmission, new generation, all of it enormously expensive. The only real question is who pays for it, and across most of the United States the answer has been the people who were already there, through their monthly rates. An earlier chapter walked through the mechanics: the regional capacity auctions, the grid operator’s own analyst pinning billions of dollars in higher costs on data-center demand, the residential rates that have climbed faster over the past five years than at any point in American history.

The part that belongs here, in a chapter about what it is like to live next to one of these things, is the unfairness baked into the arithmetic. The cost of serving a giant new customer — a 500-megawatt data center — is spread across everyone in proportion to the power each already uses. The data center pays its share, but its share is figured as if it were just another customer, not the reason the new infrastructure had to be built at all. So a household whose own usage hasn’t budged watches its bill climb because someone else’s data center showed up.

It is the same move as the air monitor at the fence line and the water permit that ignores how long an aquifer takes to refill: a number that is technically correct and silent on the question that actually matters — who caused the cost.

No smokestack here, no hum. But every month, in tens of millions of households, the bill is higher than it would be because the grid is being built out to run compute most of those families will never knowingly touch — and since low-income households spend a bigger share of their income on electricity, an increase that merely stings a median family can be ruinous near the poverty line.

What the Lights Are Like

Light gets less attention than the noise, the air, and the bills — but it reaches more homes, over more ground, than any of them.

A data center campus is lit all night, every night, by high-intensity security and operations lighting, and the design almost always puts operational needs ahead of the neighbors. A bedroom that faces the facility gets enough light, all night, that the people sleeping in it buy blackout curtains. Yards and patios go unused after dark. The night sky washes out for miles.

The health cost of that is well documented. Light at night scrambles the body’s circadian clock, suppresses melatonin, and wrecks sleep — and it tracks with higher rates of obesity, diabetes, heart disease, depression, and several cancers, in doses far below what you’d need to read by. In children, whose internal clocks are still forming, the effects on metabolism and growth appear to follow them into adulthood. It takes an ecological toll too, killing migrating birds in collisions and throwing off the behavior of nocturnal animals.

The fixes have existed for years — “dark sky” fixtures that aim light down instead of out, motion-activated lighting, warmer-colored lamps — and data centers mostly skip them, because they cost a little more. In most of the country, light pollution isn’t regulated at all, so the resident at the window has no one to call.

None of this is abstract. It is the daily life of specific people, in specific houses, who were never asked for any of it. The next chapter is about how it gets approved over their objections.
