Sir Mark Walport gave a series of public talks on energy at Science and Discovery Centres across the UK between September 2015 and April 2016. In these talks he explored how we could power the UK in the future. These slides come from the last talk given in Birmingham, but differ only slightly from the slides used in earlier talks.
