The debate spurred by my Oct. 30 post about energy efficiency policies in California is generating plenty of heat, showing that even within the climate movement there's lingering resistance to government regulatory power.
As readers will recall, a major report by the California Council on Science and Technology was spun by Andy Revkin at the New York Times to downplay the need for a rapid strengthening of regulations on energy efficiency. I took Revkin to task for misstating the CCST report's main conclusions, and Joe Romm at Climate Progress ripped into Revkin with his usual caffeinated brio.
Since then, the debate has continued with long posts by Brad Plumer at the Washington Post, by Revkin again, Dan Lashof of the Natural Resources Defense Council, David Roberts at Grist, Matt Hourihan at the Information Technology Blog and Gar Lipow at Grist (updated below). Here are my take-aways:
Brad Plumer makes some substantive points. He supports my contention that a strategy of strengthened government regulations focused largely on energy efficiency, which the CCST report says could attain a 60 percent emissions reduction by 2050, would be a big deal:
First, let’s put those numbers in context. If California did manage to slash emissions 60 percent below 1990 levels by 2050, that would be a mind-boggling shift. And, as former Union of Concerned Scientists clean-energy director Alan Nogee points out, California’s per-capita emissions are already much lower than many other parts of the United States, due to scant coal use and strict building codes. There are fewer “easy” cuts left to make. If California can cut emissions 60 percent with existing technology, other states could presumably do more.
But he also notes that the CCST report's calculations for a 60 percent reduction rely on widespread electrification, which is itself a climate challenge:
As the CCST found, the most feasible way for California to cut emissions would involve doubling its electricity use. Buildings would get heated with electricity rather than natural gas. By 2050, some 60 percent of cars would have to be plug-ins rather than combustion-powered. And all that extra electricity would need to come from clean sources. That’s a dilemma. If the state relies too heavily on wind and solar, it’ll be difficult to balance fluctuating supplies when the wind’s not blowing or sun’s not shining. The state might have to burn natural gas to balance the load, causing it to miss its targets.
Something else will be needed. Maybe Californians will rekindle their love affair with nuclear power — the CCST found that 30 new reactors could provide two-thirds of the state’s power in 2050, though that means figuring out how to deal with the waste and alleviate public fears. Or perhaps engineers will find a way to capture carbon-dioxide from coal and gas plants and stash it underground. But that’s still a ways off. The same goes for storage technologies and smart grids to smooth out wind and solar supplies. Solar already has a lot of potential as is — happily, electricity use tends to peak when the sun is shining — but higher levels of solar (say) will require new ways to store that energy for darker hours.
Andy Revkin's follow-up to his earlier column principally consists of reposted responses from Alan Nogee and Thomas Crowley. I couldn't figure out the point of Crowley's rambling piece, while Nogee basically supports Joe Romm. Among Nogee's comments is this:
... the analysis provides strong support for “deploy, deploy, deploy” being the top priority, since it shows we can get 3/4 of the way to the 80% reduction targets with existing technology, even in the challenging California case.
In his follow-up, dated Nov. 2, Revkin promises "more amplification coming soon from me, Nate Lewis, Jane Long and others." I'm looking forward to his post.
Dan Lashof, who is director of NRDC's climate and clean air program, echoes Nogee's comments about the 60 percent strategy being a necessary starting point. He delicately positions himself above the fray, lamenting the "rancorous and somewhat silly debate." Then he delves deep into the weeds to make a few worthwhile clarifications, such as the role of natural gas as an emissions-reducing strategy for the short term but not the medium or long terms.
David Roberts, in contrast, doesn't really engage with the issues. While he usually is a top-notch reporter and analyst, in this post he sets up a straw man argument, claiming that Romm and I believe that "it's all about deployment." He then swats down his straw man with a pox-on-both-houses wave, saying the "debate seems pointless."
For the amount of attention it gets, you'd think that settling this debate is the crucial first step in developing a policy plan or a political strategy. You'd think the "enough technology" question must be answered before anyone can move forward. But as I see it, pretty much nothing hinges on the answer. Indeed, I find the whole debate baffling and confounding.
After Roberts finishes smashing his straw man, he settles down and more or less admits that the "deploy, deploy" strategy is correct. As he notes, "Even the most enthusiastic fans of deployment acknowledge the need for innovation."
Yes, that's true -- Romm, I and others are arguing that what's important is to use government regulatory authority to push the deployment of existing carbon-reducing technologies. This deployment push will itself provide market signals that will drive innovation by the private sector -- which, multiplied by government investment in clean energy R&D, will help push further carbon reductions throughout the economy.
In contrast, many of the "breakthrough technologies" crowd have ignored or outright opposed government regulatory strategies for energy efficiency, instead advocating investments in long-term, futuristic technologies and espousing the muddled centrist ideology known as High Broderism (after the late Washington Post columnist David Broder).
The International Energy Agency's Nov. 9 release of its new World Energy Outlook report should prove once and for all that waiting for a technological Godot to arrive is not a feasible strategy. As Joe Romm points out about the IEA's projections, "Those who counsel waiting for breakthrough technologies are urging us on a path that is unsustainable, irreversible, potentially catastrophic, and economically indefensible."
Matt Hourihan at the Information Technology Blog swings back and forth and lands finally in the breakthrough camp. His post concludes:
We are much better off optimizing our innovation system to deliver technologies that can be sold wherever there are burgeoning populations attempting to climb out of energy poverty. Incremental innovation, through deployment, no doubt has a role to play. But if deployment is our lead strategy, we never get where we need to go.
This should be no surprise because the blog is sponsored by the Innovation Technology and Innovation Foundation, a Washington advocacy group funded largely by the tech industry.
* Update: I just noticed Gar Lipow's post earlier today on Grist, in which he identifies himself with the pro-regulatory "glass is 100% full crowd." He argues that the CCST study underestimates the potential of existing low-carbon technologies because it focuses only on those that can be deployed through California state policies. In this way, Lipow writes, the study ignores technologies that need national implementation, such as a renewables-powered grid requiring interstate long-distance transmission.
