What happens when millions of electric cars become part of the energy grid? And could the key to cheaper, cleaner power already be sitting in your driveway? And why are so many automakers pushing back against EV targets?
This week on Cleaning Up, host Bryony Worthington speaks with Fiona Howarth, founder of Octopus Electric Vehicles, about the rapid transformation of the global car industry and the powerful role electric vehicles are beginning to play in the energy system. From her early fascination with clean energy to building one of the UK’s most innovative EV businesses within Octopus Energy, Fiona shares the inside story of how electric mobility moved from niche curiosity to mainstream disruption. She explains why falling battery costs, bold policy like the UK’s ZEV mandate, and fierce competition from Chinese manufacturers such as BYD are accelerating the transition faster than many expected.
The conversation explores how EVs are evolving beyond transportation. With vehicle-to-grid technology, cars could become distributed batteries: storing renewable power, stabilising the grid, and even providing drivers with free electricity for their journeys. It’s a vision that could reshape both the energy market and the economics of driving.
But as some companies race ahead, some traditional automakers are pushing back, asking for slower timelines. Fiona argues that the real risk isn’t moving too fast, it’s backing the wrong players in a historic technological shift.
