This week we focus on the UK's digital energy switchover - like TV and banking, retail energy is getting a 21st-century upgrade. But 1 in 10 UK adults are not internet users, and the same proportion are in fuel poverty. Can a digital energy future close this gap, rather than widen it? From smart kettles to vehicle-to-grid charging, and everything in between, our guests paint their vision for the future and consider how to take everyone along, including and especially vulnerable consumers.
