The Sherwood Forest interviews are a series of clips with leading experts in the field of energy research from the University of Nottingham.

We decided to film in the famous forest because it is an icon of Nottingham and a fine example of the natural environment scientists want to preserve.

It's also a nice break from the office and laboratory!

Our thanks to those at the forest for allowing us to film. More about Sherwood forest at www.sherwoodforest.org.uk
