US electricity bills are jumping as tech giants lock up nuclear power for AI data centers, and it's bad news for ordinary families and good news for Microsoft, Amazon, and Google.

• AI data centers are pulling the cheapest, most reliable power off the public grid, driving a huge spike in the wholesale electricity auction that serves 67 million people.
• The average family in that 13-state region faces about $70 more per month by 2028, with the total bill running into the hundreds of billions over eight years.
• Microsoft, Amazon, and Google are striking private deals to restart old reactors and build small new ones wired straight to their campuses, cutting the public out entirely.
• Dirty coal and gas plants that were set to close are being kept alive to cover the gap, even as the "clean" nuclear power gets reserved on paper for AI.
• China is doing the opposite — one national plan that moves data centers to the empty interior where cheap hydro, wind, and solar sit unused, avoiding the grid fights slowing the US down.

Outlook: US power bills will keep climbing as AI demand outruns the grid, and the split between corporate private power and a strained public system is expected to widen.
