Renters Could Soon Power Homes With Their Electric Cars

Robin Sands only buys half his electricity from the grid, and he doesn't even own his home.

The Wollongong renter has cracked the code on slashing energy bills without permanent installations. With his landlord's approval, he mounted two portable solar panels on his roof, charges two lithium batteries, and cooks on a $180 portable induction cooktop that's transformed his kitchen into an energy saving powerhouse.

His setup cuts his daily electricity needs from 6 kilowatt hours to just 2. The panels generate up to 4 kilowatt hours on sunny days, powering his kitchen appliances and charging batteries that take over after sunset.

Now advocacy group Rewiring Australia wants to make this kind of independence standard for all renters. They're pushing the New South Wales government to require special plugs in rental garages that would let tenants power their homes directly from their electric vehicle batteries.

The technology already exists. A typical electric car battery can power an average house for five days, roughly double the capacity of large home batteries.

The catch? Current rules require vehicle-to-grid power boxes to be hardwired into homes, which demands landlord approval and can't move with tenants. The proposed standard plug would change that completely.

"We're all going to start using cars that have a gigantic battery in them," says Rewiring Australia chief executive Francis Vierboom. "Connecting your car at a scale that can run your house can take a big bite out of your energy bills."

The timing couldn't be better. Starting July 1, NSW residents with smart meters can access three hours of free daytime electricity, capped at 25 kilowatt hours, through the federal Solar Sharer Offer.

Renters could charge their cars during those free hours, then use that stored power during expensive evening peak times. No solar panels required.

The Ripple Effect

The push addresses a stubborn inequality in Australia's energy transition. Rental homes lag far behind owner-occupied properties in energy efficiency, with the gap especially wide in low-income and regional areas.

Simple upgrades like insulation could save renters up to $750 annually, according to government estimates. But landlords rarely invest in improvements that benefit tenants more than property values.

Portable solutions flip that script. Renters gain control over their energy costs without needing landlord cooperation for major renovations.

The NSW government is currently accepting submissions on minimum energy efficiency standards for rentals. Rewiring Australia's proposal includes allowing balcony solar systems and requiring electric appliances to replace gas fittings when they reach end-of-life.

For Sands, the effort has paid off immediately, and he's enjoying watching his power bills shrink month after month.
