Topic: Energy Intensity

[Episode #104] – 4-Year Anniversary Show

In this anniversary episode, we welcome back Jonathan Koomey to talk about some of the interesting developments and raucous debates we have seen over the past year. We’ll be talking about the flawed concept of “committed emissions” and how we should be calculating future emissions instead; we’ll expand that discussion and critique the conflicting stories that we’ve been hearing about the expectations for coal usage and emissions in India; we’ll review some of the efforts to execute so-called “just transitions” in coal country; we’ll take a little excursion into a recent raging dialogue on Twitter about RCP8.5 which had its genesis in the PhD thesis of our producer, Justin Ritchie, which we explored in Episode #49; we’ll move on from there to discuss the communication challenges around climate change science, and what’s wrong with the kind of hysterical journalism being practiced by writers like David Wallace-Wells in his book The Uninhabitable Earth; we’ll take a look at Jon’s latest research on the energy demands of Bitcoin mining; we’ll consider the rapid deployment of utility-scale storage and what that might mean for the future of the grid; we’ll review Jon’s update of global energy intensity data and ask what it all means; and we’ll wrap it up with another look at the energy transition modeling work of Christian Breyer’s team at Lappeenranta University of Technology in Finland, which we explored in Episode #95.

[Episode #32] – Resources and Economy

Full Episode

The notion of “decoupling” energy consumption from economic growth has become vogue in policy circles, but how much evidence is there that it’s really happening? If the energy intensity of our economy is falling, are we sure that it’s becoming more efficient, or might we just be offshoring energy-intensive industries to somewhere else…along with those emissions? If energy reaches a certain percentage of total spending, does it tip an economy into recession? Is there a necessary relationship between energy consumption and monetary policy? Is there a point at which the simple fact that we live on a finite planet must limit economic growth, or can economic growth continue well beyond our resource consumption? Can the declining EROI of fossil fuels tell us anything about the future of the economy? And can we have economic growth using clean, low-carbon fuels, or might transitioning to an economy that produces zero net new carbon emissions put the economy into recession and debt?

To help us answer these thorny questions, we turn to an expert researcher who has looked at the relationship between energy consumption and the economy over long periods of time and multiple economies, and found some startling results with implications for the Federal Reserve, for economic policymakers, and for all those who are involved in energy transition.
