Throughout the 2020s, climate change will be a huge topic of conversation, and part of that conversation will be about energy. Renewables are seen as the future, but just how futuristic are they?

At the National Trust, some of the properties we care for have been lit, heated and powered by renewables for over 100 years. As we move towards our goal of sourcing 50% of our energy needs from renewable sources, in this five-part podcast series, we join professor Lucy Green as she embarks up on a 750-mile journey across our properties to investigate if lessons from our past may help us achieve our sustainable future.

The production of this podcast has been made possible by BMW i.
