Thanks Jim for posting this RIP.
I was really sad to see the passing of David McKay at just 48. His work on emissions mitigation was groundbreaking. The UK and the world has lost a true climate change/emissions mitigation champion.
His brilliant book is free and is on line and is a must read for anyone truly interested in climate change/emissions mitigation.

"We need a plan that adds up. We need to stop shouting and start talking, and if we can have a grown-up conversation, make a plan that adds up and get building, maybe this low-carbon revolution will actually be fun. "
"We just need to understand the numbers. I'm absolutely not anti-renewables. I love renewables. But I'm also pro-arithmetic."
