There’s a fantastic book series based on exactly this: The Change Series. This is a double storyline with the Emberverse series in which the present time beginning in March 1998 loses electricity and “most forms of high-energy-density technology” due to “The Change”, which occurs at 6:15 p.m. Pacific Standard Time, March 17, 1998.
The companion series, which was written first, is the Nantucket Series, in which the island of Nantucket is transported back in time to 1250 BC due to something called “The Event”, the same Event that caused The Change. But— they got to keep all their physics intact.
