Our latest episode explores the routes to decarbonising domestic heat. Hear from expert guests, Dr Tim Rotheray and Adam Madgett, about the need to balance both sides of the heating equation - energy efficiency and clean heating sources. We focus on the options for keeping warm without harming the planet, from electricity to heat networks to green gasses. 83% of UK homes have gas-fired boilers today, but what will the future of heating look like?

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.

Our first episode takes place at the intersection of food and energy - two systems which are central to human wellbeing and climate change. Getting food from farm to table is taking a toll on the environment, and 1/3 of all food produced never gets eaten. While the story differs between emerging and advanced economies, energy is at the heart of the challenge wherever we are in the world. Our guests walk us through food's journey, from how it's kept cold to how it's sold, and ask us to rethink society's biggest questions: how can we feed the world without destroying the planet?
