> There is this appalling delusion that people have that we can take this thing that is currently producing 1% of our electricity and we can just scale it up and if there is a slight issue of it not adding up, then we can just do energy efficiency,” he said. “Humanity really does needs to pay attention to arithmetic and the laws of physics – we need a plan that adds up.”

> Prof MacKay had previously avoided being drawn into the political debate about energy, but told Lynas: “I have always tried to avoid advocating particular solutions but maybe because time is getting thinner I should call a spade a spade.”

> The key for the UK, he said, was a zero-carbon solution that works in the winter, when energy demand is highest but sunshine is lowest and winds can drop for days at a time. “The sensible thing to do for a country like the UK, I think, is to focus on CCS, which the world needs anyway, and nuclear,” said Prof MacKay.

> The decision on a new nuclear power plant at Hinkley Point, which the government hopes will be the first of a new generation of plants, has been delayed until September.

> “Then if you ask what is the optimal amount of wind and solar to add in then the answer is going to be almost zero,” he said. “I love wind turbines – they are the cathedrals of the modern age – but they are a waste of money if you have a low carbon solution that gets you through the winter … because when the wind blows you are going to have to either turn them down or something else down that you have already paid for like nuclear or CCS.”

Maybe he would have changed his mind as prices and delivery timelines diverged but many of the people who were most enthusiastic about his work because it reflected their nuclear preference didn't, so who knows.

Though maybe his kind of person that liked nuclear and heat pumps and EVs all just changed their mind based on new evidence and we are left with the people who mysteriously like nuclear but don't want to use the output for heat and transport.
