Peer Review of Wendover Production's "The Nuclear Waste Problem" Youtube Video

Above images from Nuclear Energy Waste--Making Mountains Out of Mole Hills

The YouTube video, The Nuclear Waste Problem was published on November 21, and went viral with about half a million hits in a few days. I learned of its existence when it was presented to me as irrefutable evidence for why nuclear can't be part of the climate change solution.

Technically, it's quite well done. The graphics and music are appealing. The transcript is about two and a half pages long, single spaced. Unfortunately, the narrative found in that transcript is remarkably inaccurate. If the graphics and music are lipstick, the narrative would be the pig.

Simon Holmes à Court thinks 100% Renewable Energy has been Demonstrated to be Possible in Australia

More Twitter activity from Simon.

He starts by asking:
nuclear twitter: does anyone have a simple LCoE for a nuclear power station? i'd love to better understand the economics.
If he's an energy expert, I have to wonder why he's asking for data from strangers on Twitter. You wouldn't see the likes of James Hansen doing that for one of his many papers published in Science and elsewhere. And as is almost always the case with his tweets, you're never sure what he is trying to say. Did he mean an equation? An example calculation? Examples of LCOE for nuclear? A spreadsheet?

It's not just me. Also not sure what he is asking for, Suzy Waldman handed him a link to Lazards which listed various LCOEs and an EIA link that explained the concept of LCOE.


I, in turn, responded to Suzy:



Tom Biegler responds to me:

Thanks. And I don't suppose they include load leveling costs to turn wind and solar into a product that users might like, want and need.
I, in turn, respond to him with a link to an Energy Matters article that tries (but apparently often fails) to explain why you can't compare the LCOE of sporadic sources to baseload sources:
Exactly ...if you want to compare LCOE of wind and solar to baseload nuclear LCOE, you find what it would cost to make them do baseload (answer offshore wind in UK is six times more expensive than Hinkley). 
Missing the point of the Energy Matters article entirely, Simon posts a typically cryptic response devoid of capitalization:

Environmental Progress--The Power to Decarbonize

Figure 1

Environmental Progress has a new study out that I found very compelling.  It's just raw data arranged in a manner that paints a global picture. Critics can't punch holes in it by attacking assumptions chosen because it doesn't have any. In a nutshell, it shows a strong global correlation between nuclear energy use and lower carbon intensity, but no such correlation between wind and solar.

It took some effort for me to understand how the graphic shown in Figure 2 below was derived. To make sense of it I had to drop down into the appendices to look at the data for each country:
In service to transparency, we have reproduced all 68 national carbon intensity of energy charts used in this analysis in our appendix, in addition to publishing the aggregated national charts.
Each dot represents a given country's carbon intensity at a given level of annual nuclear, or wind, or hydro, or solar output. Each data point used to plot the thick curve is a kind of average of the dots at a given annual electricity output for nuclear, or wind, or hydro, or solar. The carbon intensity in countries can grow or retract with the addition or reduction in any given energy source (nuclear, wind, solar, or hydro). In Japan, for example, a reduction in nuclear caused an increase in carbon intensity.

I put my anti-nuclear hat on to find a way to punch holes in the results. Could the different horizontal scales be hiding something? Are plots using the same scale hiding something in the clutter for wind and solar? To resolve those issues I overlaid the nuclear and wind graphs at the same scale and magnified the results to make them more visible (see Figure 1).

Simon Holmes à Court would support fast, cheap, safe, small, flexible nuclear

This post is motivated by a Tweet by Simon who very much thinks he has an open mind about nuclear energy ...like all antinuclearists, but like all antinuclearists, he really doesn't. He's like the creationist who would love to believe the theory of evolution ...if the data would only support it. Classic case of self-delusion combined with a little cognitive dissonance.

His Twitter homepage intro:
interesting theory — data me up! 'likes' are bookmarks not endorsements. ATTN: loopy left & RWNJs: if you think i'm one, you're almost certainly the other.
Bottom line, I would not have had to "data him up"  if he really had an open mind because he would have already sought out the data. Below, he gives an attaboy to a supporting tweeted chart critiquing nuclear. I gave him a few other charts to think about, but no love for me (link):



His supporter then posted a strawman argument coupled with another graph and got another attaboy. Those graphs shown below are actually a positive sign showing how the combination of low carbon sources has joined forces but this guy somehow sees this as evidence that nuclear should not be part of the mix:

Now for the bad news: 75% decline in insect biomass over 27 years


In a nutshell, no insects = no ecosystem.

I recently took a trip to the Brazilian Cerrado and Pantanal. Click on this link to see photos and videos of some insects I saw there. I'll add a few random insect photos from other places I've been as well. Click on any photo to open a higher-resolution slideshow.

Monbiot's article is worth a quick read unless you're prone to depression (last of the above links):
Every year I collected dozens of species of caterpillars and watched them grow and pupate and hatch. This year I tried to find some caterpillars for my children to raise. I spent the whole summer looking and, aside from the cabbage whites on our broccoli plants, found nothing in the wild but one garden tiger larva. Yes, one caterpillar in one year. I could scarcely believe what I was seeing – or rather, not seeing.
He suggested a few solutions, like limiting pesticide use (while acknowledging that we still need to grow food). GMO corn has reduced the use of insecticides for rootworm and the corn borer, but the anti-GMO crowd (similar in many ways to the anti-nuclear one) will resist that idea to their graves. And then there are the layers of complexity, like the permanent mandated consumption of corn ethanol put into place via rare bipartisan cooperation.

He made a salient point about the growing of food for livestock. From The Breakthrough Institute (co-founded by Shellenberger) Where’s the Fake Beef? Eating Meatless Meat Is Safe for You and the Planet:
The Impossible Burger—the meatless burger that bleeds—has recently been lambasted by some environmental activists for using genetic engineering to make the burger taste and look like meat. It’s a strange accusation, to say the least. The environmental impacts of meat production are large and complicated; reducing them will require modern tools and technologies. And few innovations have as large a potential as meatless meat to mitigate ecological impacts while meeting global demand.
