[Episode #54] – Resource Limitations

How do we know at what level our consumption is sustainable, and when we’re in planetary overshoot? How do we quantify what the planet’s capacity is to meet human demands, and how much of that capacity is renewable, and how much of it is just being permanently depleted? And once we had a way to quantify that, what would we do with that information? Would we use it to inform our actions and avert overpopulation and disaster? Would we ignore it at our peril? Or would reality just unfold in some messy fashion along a default path somewhere in between? Is a deliberate transition to a sustainable energy system even possible?

Our guest in this episode created a scientific methodology called “ecological footprint analysis,” a kind of ecological accounting, to inform policymakers about our resource demands on the world as compared with Earth’s ability to meet those demands. Earth Overshoot Day, which the Global Footprint Network calculates every year, arrived on August 2, meaning “that in seven months, we emitted more carbon than the oceans and forest can absorb in a year, we caught more fish, felled more trees, harvested more, and consumed more water than the Earth was able to produce in the same period.” After listening to this discussion, you’ll never quite think of energy transition the same way again.

[Episode #33] – Fracking Follies

Full Episode

The US Energy Information Administration (EIA) regularly updates its estimates for how much oil and gas might be recovered in the future, and at what rate. With the application of new technology from year to year, those estimates generally keep going up. But it’s important to remember that they are just estimates — and the devil is always in the details.

Our guest in this episode is a career geoscientist who has diligently delved into those devilish details. In his new reports, he finds that EIA’s Annual Energy Outlook 2016 seems to significantly overstate how much oil and gas might be recovered using fracking technology, with estimates for shale gas and tight oil production that exceed the estimates for how much of those resources are even technically recoverable. In this extended and technically detailed interview, we discuss EIA’s most recent forecasts and try to understand what’s realistic for future US hydrocarbon production.
