I am familiar with Jacobsen and Delucci’s articles. Peer reviewed is good, but it’s best to interpret it more as “These guys aren’t complete cranks” than “This is definitely right.” This article, for example, is also peer reviewed:
I’m posting it just to point out that Jacobsen and Delucci’s assertions do not, even remotely, represent a consensus in their field, or any of the other fields relevant to this, and not because I agree with everything Trainer says. In fact, I’m much more optimistic than Trainer, and, though all of his critiques have some merit, there are only two which I feel are really anywhere near as bad as he claims they are, and, of those two, there is only one that I personally have the expertise to address. (Though a quick google search on Jacobsen and Delucci will turn up plenty of people with the relevant expertise talking about the other one)
The only one I can really speak about is the issue of large-scale storage. Though I no longer work in the field, until about three years ago I was doing research in, specifically, the field of storing solar energy via electrolysis, but I’m at least familiar with the literature on other methods of storage (all, admittedly, from the materials science side, not the civil engineering side.) I still stay in touch with my friends in the field, and thus am aware of any serious breakthroughs.
Throughout, J&D blithely (and implicitly) assume that solving the large scale storage issue is as much a done deal as the power generation issue, and it is very much not. Wind power and both concentrated and PV solar have already been demonstrated to scale, so their assumptions are warranted in that case. They never, however, even directly include the extra inefficiency from conversion to a storage medium and back or the extra infrastructure necessary for storage in their calculations. These would be necessary even in a situation where storage scaling was a done deal, like it would be if, hypothetically, platinum and/or iridium, and hopefully indium, were as cheap and plentiful as iron.
Unfortulately that is not the case. Most of the ways people are talking about storing energy that have the potential to scale (e.g., don’t require exotic metals or enormous amounts of energy to manufacture compared to their storage capacity.) are not even near the required efficiency in the lab, much less at scale (a few are getting close, and are very promising, but are not at the point where we can be fully confident that they’ll scale).
I do believe that it is very likely possible to go entirely renewable, though I personally think that getting off carbon completely in the timeframe of a couple decades would probably require nuclear to tide us over until we complete the transition to renewables. I also think that we absolutely should do everything in our power to make the transition to renewables. I don’t think pretending it’s going to be easier than it actually will be is helping anything, though.
