David MacKay – last interview and tribute Mark Lynas; 27 Apr 2016

I had the honour of recording David MacKay’s last interview, on 3 April 2016. The idea was to present him with the Breakthrough Paradigm award because due to his illness he was unlikely to be able to travel to the awards ceremony in June 2016. However, we talked about a lot of different things, and together with David’s wife Ramesh I wanted this video and tribute to appear beforehand in full and unedited. David obviously knew he didn’t have long, and was consequently more forthright than he had perhaps been in previous interviews.

Without The Hot Air pete; Mythic Beasts; 15 Apr 2016

It’s with great sadness we learned of the death of Prof Sir David MacKay, FRS. He taught three of the Mythic Beasts founders information theory in 1999–2000, a fascinating and stunningly well-lectured course. The textbook Information Theory, Inference, and Learning Algorithms is freely available to download. Prof MacKay believed it was possible to make the world a better place.

RIP Sir David MacKay Athene Donald; 16 Apr 2016

Many people have been paying tribute to David MacKay, who died on Thursday, and I would like to add my own voice. He was an extraordinary man who contributed so much to physics and wider societal issues during his tragically short life. Although I never worked directly with him, nor even interacted with him much during the many years we worked in the same department (Cavendish Laboratory) in Cambridge, nevertheless somehow his character pervaded the world around him and made us all more aware of the importance of finding ways to communicate beyond our own communities.

A tribute to former DECC chief scientific adviser Sir David MacKay Dr Emily Shuckburgh, Fellow, Darwin College, Cambridge; 16 Apr 2016

He was an intellectual genius with immense humanity, a strong sense of social justice and an endearing sense of humour. He had once-in-a generation brilliance – a polymath whose works were seminal across an unimaginable span of subjects.

David MacKay Matthew Garrett; 14 Apr 2016

The first time I was paid to do software development came as something of a surprise to me. I was working as a sysadmin in a computational physics research group when a friend asked me if I'd be willing to talk to her PhD supervisor. I had nothing better to do, so said yes. And that was how I started the evening having dinner with David MacKay, and ended the evening better fed, a little drunker and having agreed in principle to be paid to write free software.

In 2008 UIT Cambridge published David MacKay's book, Sustainable Energy - without the hot air. I have worked with him as editor and publisher and known him as a friend in the eight years since then. These recollections are from my personal experience, so they focus on his book and related events.

Carbon Pricing

Price carbon — I will if you will David J. C. MacKay, Peter Cramton, Axel Ockenfels & Steven Stoft; Nature; 12 Oct 2015

To forge a strong climate accord in Paris, nations must agree on a common goal in everyone's self-interest, say David J. C. MacKay and colleagues.
Negotiations at the United Nations climate summit in Paris this December will adopt a 'pledge and review' approach to cutting global carbon emissions. Countries will promise to reduce their emissions by amounts that will be revised later. The narrative is that this will “enable an upward spiral of ambition over time”. History and the science of cooperation predict that quite the opposite will happen.
Climate change is a serious challenge because the atmosphere gives a free ride to countries that emit. If some nations sit back and rely on others' efforts, the incentives for anyone to act are weakened. Review of the first phase of the Kyoto Protocol at the 2012 UN climate meeting in Doha, for instance, resulted in Japan, Russia, Canada and New Zealand leaving the agreement, frustrating those who kept their promises.
Success requires a common commitment, not a patchwork of individual ones. Negotiations need to be designed to realign self-interests and promote cooperation. A common commitment can assure participants that others will match their efforts and not free-ride. A strategy of “I will if you will” stabilizes higher levels of cooperation. It is the most robust pattern of cooperation seen in laboratory and field studies of situations open to free-riding2.

Sustainable Energy - Without the Hot Air with David MacKay Harvard University; (uploaded) 25 Oct 2010

David MacKay, Scientific Advisor to the Department of Energy and Climate Change, UK addressed energy issues at a macro and micro scale with the Harvard University community and beyond.


I have started an open-source wiki [currently taken down because of vandalism by hackers] that contains estimates, for every country, of sustainable energy options. I encourage contributors to make these estimates in the same style as the book. Rough, clear, and focussing on the big fish. Hopefully this will be a useful teaching resource, and a useful enhancement to the book itself. The wiki also has a page for extensions to each chapter of the book.

Think big on renewables scale DavidMacKay; Guardian; 29 Apr 2009

Current renewable installations can only deliver small amounts of energy; so when we build clean energy facilities, we have to think big, says David Mackay

Criticisms & Attacks

Is David MacKay becoming part of the problem? Mark Brinkley; blog; 11 Mar 2010

since he took the Queen's Shilling and became Chief Scientific Advisor of the Department of Energy and Climate Change in September 2009, he has used his new found influence to promote air source heat pumps as the answer to our problems. "While in theory ground-source heat pumps might have better performance than air-source, because the ground temperature is usually closer than the air temperature to the indoor temperature, in practice an air-source heat pump might be the best and simplest choice," he writes in his book. And yet there a dozens of knowledgeable people out there who are distinctly queasy about air source heat pumps and think they may just make matters worse,

British Energy Demand, and Professor MacKay’s estimate of it: an explanation of the differences Andrew; Energy Numbers; 29 Jun 2010

In “Sustainable Energy Without the Hot Air”, Professor MacKay compares an energy demand of 195 kWh/d with his calculated British renewable resource of 180 kWh/d, and comes to the conclusion that Britain cannot power itself from renewables. But in reality, British energy demand is 155 Mtoe/y. That’s the confirmed 2008 number, from the official Digest of UK Energy Statistics. (pdf, see Table 1.1, Final Consumption minus Non-energy use). That’s less than half the demand figure used in the book, when looking at whether his calculated renewable resource is enough. When we compare the renewable resource with the current demand figure, we see that the resource is more than double current energy demand: and that’s before any energy efficiency measures. And that makes a huge difference: by using the real figure for demand, we see that the UK renewable resource is much higher than current energy demand, so Britain could comfortably power itself from its own renewables.
Comment on blog by Patrick Stewart; 4 Apr 2011
To be fair, that comparison on page 103 is between his two ballpark figures based on back of an envelope estimates. His actual conclusions on what is and isn’t possible are much later in the book (page 203 onwards), but as you seem to half-acknowledge above, on the following pages (104 and 107) he compares both of these estimates to official figures. He finds that he overestimated consumption by about 50% as compared to the same DTI figures you’re using except from 2006 rather than 2008; mostly by including the energy used to make things that isn’t expended in the UK. So pretty much your entire article is already in the book. He uses those corrected figures, with further reductions due to efficiency, in the rest of the book, including in his actual conclusions.
What you haven’t written about at all is that he also finds that his total renewable energy potential estimates were very optimistic, about 3-10 times higher than similar estimates by several other groups.
I don’t really know why I’m posting this, you’re clearly already aware of it, it’s in you graphs; I just can’t understand how you can complain about Mackay inflating his figures while also being aware that they’re lower than yours in his conclusions on pg 204. If you actually read the text on page 103 it clearly says “Now we will see if these estimates are correct”, not “so here I have conclusively proved renewables are insufficient”

Solar energy in the context of energy use, energy transportation, and energy storage David J C MacKay FRS; Article submitted to Royal Society; 2013?

Taking the United Kingdom as a case study, this paper describes current energy use and a range of sustainable energy options for the future, including solar power and other renewables. I focus on the the area involved in collecting, converting, and delivering sustainable energy, looking in particular detail at the potential role of solar power.
