Live outdoor productions traditionally use diesel generators because of the amount of power needed.
Tuesday evening’s instalment of Winterwatch, which is presented by Chris Packham, Gillian Burke and Iolo Williams, was powered differently.
Julian Hector, head of BBC Studios Natural History Unit, said: “Everyone … is punching the air at the prospect of finding a way to make our productions more sustainable.
Itâs time to relax with a gorgeous mindful moment. Join us and listen to the calm sounds of Derwent Waterâs lapping water and wildlife, as you unwind with some beautiful scenery.
“This is a superb development for us and the environment, and exactly the kind of thing we want to do more of.”
