Topic: Rebound Effect

[Episode #86] – Is Transition Worth It?

Are investments in energy transition, especially for public dollars in the form of incentives or subsidies, worth it? Do investments in energy efficiency truly pay off, or does efficiency just make energy cheaper because we’re using less of it, encouraging customers to use more of it—a phenomenon known as the rebound effect, the backfire hypothesis, and the Jevons Paradox? Is public support for rooftop solar systems worth it, once we add up all its costs and benefits, or would it be better to support utility-scale solar projects, or something else entirely, like efficiency? Do wind and solar farms, and electric vehicles, always deliver climate benefits, or does it depend on the power mix of the grid to which they’ll be connected? And even if we determine answers to these questions, for how long are those answers valid?

These are all difficult questions, but our guest in this episode has investigated all of them, and she shares her insights at length in this wonky but accessible discussion. If you worry that the rebound effect might mean efficiency isn’t worth it, you definitely need to listen to this one.

[Episode #68] – Environmental Economics

In an economy as large and complex as the United States, how can we tell when our efforts at energy transition are working? How do we calculate our carbon emissions? How do we know why emissions fell, especially if increased efficiency can rebound into more consumption, an effect known as the Jevons Paradox? How should we calculate the cost of damage due to climate change, and how we should choose the discount rates we use in evaluating investments to stop it? And even if we knew the answers to all these difficult questions, how should we act, given how little certainty we have about the future of the climate, and of the trajectory of energy transition itself? Can economic theory even help us plot a sensible path toward energy transition and climate change mitigation? Our guest in this episode has published extensively on all of these thorny questions, and we’ll discuss that research with him, along with his current research into solar geoengineering.

[Episode #20] – Grid Evolution

Full Episode

Utilities face a host of rapid changes in a what used to be a staid business: new business models, changing supply and demand forecasts, new distributed architectures, new types of resources, new participants in the power grid that they don't control…yet they still must maintain a highly reliable power grid that operates within fairly narrow parameters.

Meanwhile, difficult questions remain to be solved, about how we’re going to manage our grid power transition, who the winners and losers will be, what destination we’re headed for, what role consumers and “prosumers” will play in the future, and what our reasons are for executing transition the way we do.

We tackle all of these issues in this wide-ranging, very geeky conversation about the “blocks and squiggles” of the grid of the future. Grid power transition, the rebound effect, energy efficiency, utility business models, cutting-edge grid power management considerations, regulation and rate design, electric vehicles as distributed energy resources… they’re all here.
