I think I did mention David MacKay's final interview before his death in the "The confused Glastonbury festival organiser" thread last year, but I wasn't aware that a Youtube video of it was available. Here's the link for the video (about 23 minutes in length) for anybody interested:
MacKay does look reasonably OK in the interview and you wouldn't guess that he was only 11 days away from death at the time. The MacKay position on low carbon energy given in the interview was that in the specific case of the UK, renewable energy is actually a waste of time because of its poor performance in the winter months, and it would be better to rely completely on nuclear power and CCS (carbon capture and storage). He also revealed that the Civil Service had never regarded solar power as ever being a viable idea for the UK, and its presence in the UK energy mix is down to politicians and lobbyists like Jeremy Leggett.
It is a bit ironic that the Lib Dem politicians who were in charge of DECC, Chis Huhne and Ed Davey, must have been effectively ignoring MacKay's expert advice in favour of taking their advice from 'Big Green', as the Lib Dems have been trying to present themselves in the last year as the political party that has the most respect for experts. To give an example, the current Lib Dem party leader, Tim Farron, attacked Michael Gove over his remarks about experts in this newspaper article:
During one of the EU Referendum campaign debates in 2016, Gove said "People in this country have had enough of experts”, in response to being asked to name any economist who backed the idea of leaving the EU. The liberal establishment seems to regard Gove's comment as being the most controversial thing that anybody said in the Referendum campaign, somehow extending the scope of Gove's comment as applying to experts in all subjects rather than just economists, with Farron describing it as "perhaps the quote of the whole campaign" (personally I thought David Cameron's comment that Britain leaving the EU might trigger World War III was a lot more controversial).
