I recently found myself a Twitter debate about transportation and greenhouse gas emissions, which started from the question of whether or not solar could replace oil. This is really a question about transportation, which I don’t normally write about, as the focus of my work in the Energy Transition has been the electricity and heating […]

“Where there is no vision, the people perish” – Proverbs 29:18 The spectacle of 300,000-400,000 people marching in the streets of New York City on the issue of the threat we face from our changing climate was an wonderful thing, and a frankly overdue level of attention for this, the greatest challenge to our civilization. And […]

I was greatly disappointed today to see Pricewaterhouse Cooper’s study, Two degrees of separation: ambition and reality: low-carbon-economy-index-2014, reprinted in an unquestioned form in multiple publications including Vox and Grist.

The gist is this: Latin America is an exciting place for […]

Having just finished Energy Transitions, the work of widely lauded energy historian and polymath writer Vaclav Smil, I am left disappointed. I must admit that I had high expectations. The book was referred to me by a senior environmental journalist, and given Smil’s reputation I was expecting a very well researched, careful collection of coherent […]
