Tesla has turned on Powershare Home Backup for the Model 3 and Model Y, which means its two volume cars can now send power back into a house during an outage. Until today, the Cybertruck was the only Tesla that could do it.

There are limits. You need a Powerwall 3, and Tesla only guarantees the feature on cars ordered since October 1. For years, Ford and GM have been selling EVs that can back up a home.

A five-stop concert tour in Quebec ran entirely on two Chevrolet Silverado EVs and a 150 kWh mobile power plant this summer. No diesel generator, and no hookup to the grid.

I went to the final show, held in a grocery store parking lot in Montreal’s Saint-Henri neighborhood, and everything from the speakers to the stage lights to the kitchen was running off batteries.
