Insight and inspiration in turbulent times.
When we hear about the emissions scenarios used in the Intergovernmental Panel on Climate Change (IPCC) reports, do we really understand what they’re assuming about future fossil fuel combustion? And what do these emissions scenarios imply about the steps needed to achieve climate policy goals and decarbonize our energy system?
How to collect that solar energy, predict it, get it to the right places at the right time, save it up for a rainy day — those are the kind of challenges our massive, spread-out, and unevenly populated country faces as we make the switch to clean energy. And it all comes down to a lesson that the Evslins learned the hard way: It’s not about getting off the grid. It’s about building a better one.
Sometimes the most heated debates are among people who almost agree. That seems to be the case with the recent Jacobson-Clack controversy, in which two groups of well-intentioned, renewable energy advocates bitterly spar over differing paths to a 100% renewable energy future. But as PCI Senior Fellow Richard Heinberg points out in his latest essay, neither side is considering one of the most crucial aspects to successfully reaching that future.
Tim Flannery drops into the studio and we discuss why, and talk about his new book (his second follow up to the highly influential The Weather Makers): Sunlight and Seaweed: An Argument For How To Feed, Power, and Clean Up The World.
But what does the transition mean for residents of Essen and the rest of the Ruhr region — the former industrial coal belt — whose lives and livelihoods have been dramatically altered by the reduced demand for coal? The answer to that could hold some useful lessons for those undergoing similar transitions elsewhere.
In this fourth episode of our climate science mini-series, we dive into the carbon cycle to understand how the greenhouse gas emissions from fossil fuels accumulate in the atmosphere. We also discuss how climate science is taught, the concepts that students struggle to understand, and what the science of human reasoning and teaching can tell us about how best to communicate this enormously complex subject to a lay audience.
Hydraulic fracturing (“fracking”) and offshore drilling garner a lot of news headlines when it comes to oil and gas issues in America, but they’re far from the only game in town, with those two drilling techniques not even constituting the majority of U.S. oil and gas production. For that, look to enhanced oil recovery (EOR), an under-regulated drilling method that has been around for over a century and could be threatening drinking water sources
Last month, California’s politicians agreed a new cap-and-trade bill to help curb the state’s emissions. This week, governor Jerry Brown signed it into law, representing a major step forward in the state’s effort to combat climate change. “Cap and trade” requires large emitters such as power plants, refineries and factories to buy permits for the greenhouse gases they release.
In a recent post I extolled public transit as a way to cut personal fuel use, emissions and expenses, for those few Americans who can use it. But I had to think hard about that view after reading two well reasoned rebuttals, from Paul in Madison, Wisconsin, and Vince in Austin, Texas.
The implications for the future of the global economy will not be pretty — but if we face up to it, the transition to more sustainable societies will be all the better for facing reality, rather than continuing with our heads in the sand.
British Petroleum (BP) publishes its Statistical Review of World Energy, venting out a few catchy phrases that the mainstream media mindlessly repeats. This time the catch-phrase was: “overall energy consumption is growing faster than renewable energies put together”. This discourse is naturally convenient to those set on promoting fossil fuels and/or detracting renewable energy. But is BP really a trustworthy source on the matter?
There is a very real trade-off between the rate at which we address climate change and the amount of economic growth we can expect during the transition to a low-carbon economy, but most economic models insufficiently address this trade-off, and thus are incapable of assessing the transition.
