Automakers are increasingly promoting cars and trucks as more than transportation, highlighting their potential to keep homes running when the grid goes down. The idea is gaining attention as severe weather and power disruptions push homeowners to look for new backup energy options.

One example comes from Texas, where resident Kenneth Kovar installed a Ford home energy setup after Winter Storm Uri left a lasting impression. With the system, drivers of certain Ford F-150 models can connect the vehicle to their electric meter and use it to supply power to the home during an outage.

The approach reflects a broader shift in the auto industry toward vehicle-to-home technology. Instead of relying only on traditional generators or fixed battery systems, some households may be able to draw electricity from a compatible vehicle parked in the driveway. That can make a vehicle part of a home's emergency energy plan as well as daily transportation.

For automakers, the strategy adds another selling point as connected energy systems become more important to buyers. For homeowners, it suggests a future in which a car or truck can serve as a backup power source when extreme weather or grid problems interrupt normal service.
