As I anticipated, my post on Tesla’s new battery provoked some pretty hostile responses, most notably from pro-nuclear diehards. I’ve written plenty on this (use the search facility), so rather than repeat myself I’ll make an observation drawing on the previous post.
Ten years ago, solar PV was a faintly hopeful technologica prospect, making a minuscule contribution to electricity generation. Today, it’s a reality that is creating massive disruption for electricity utilities around the world. As I said in the previous post, the availability of even moderately cost-effective storage removes the last big obstacle (more on the economics soon)
By contrast, ten years ago, nuclear energy was a mature technology which seemed to be at the beginning of a renaissance. Today it’s further away, in almost every respect, than it was in 2005. Construction times have blown out, costs have turned out to be twice as high or more than expected, the operating record (thanks to Fukushima) is far worse, and the various new technologies (SMRs, Gen IV) have receded even further.
None of this means that the replacement of fossil fuels with renewables+storage is going to happen under current policy settings. But such a replacement is now clearly feasible, much faster, more reliably and at much lower cost, than attempting to reboot the failed nuclear renaissance.
Backing the nuclear horse was a reasonable choice in 2005. But it’s dead, and flogging it won’t revive it.
