Amory Lovins's Comments on a Fred Pearce Post

I recently stumbled on a comment by Amory Lovins under an article by Fred Pearce at Yale 360 called Industry Meltdown: Is the Era of Nuclear Power Coming to an End?

360 holds every comment for moderation, which tends to thwart any meaningful dialog but that's a little better than no comment field at all (VOX), and much better than CleanTechnica's method of systematically censoring comments and commenters who have viewpoints that differ from that of the moderator. Watch for his confirmation bias and the backfire effect--a term that describes how people will cling ever more, ah, heartily, to a strongly held belief when confronted with facts that dispel it. There is very little difference in that respect between creationists and anti-nuclearists like Lovins.
Assuming that not all edits and comments will appear or will appear in a timely fashion, I thought I'd throw them into an article. From Lovins:
In the first five years after Fukushima, Japan has displaced 70% (64% without GDP renormalization) of its previous national nuclear output with electricity savings, renewables, and a bit of other distributed generation.

Your link is broken and your source which states that its mission is to “establish a society based on renewable energy,” is suspect. 

From Bloomberg:

From 2011 through 2013, Japan’s trade balance worsened by a cumulative 18.1 trillion yen ($169 billion), estimates Taro Saito, director of economic research at the NLI Research Institute in Tokyo. Of that amount, 10 trillion yen, or 55 percent, came from energy imports.

$169/3 = $56.33 billion
55% OF $ 56.33 billion = $30.98 billion.

2016-2011= 5 years.

5 years x $31 billion/year = $155 billion dollars lost to fossil fuel costs as a result of antinuclear fear mongering that has closed Japan's nuclear. How many nuclear power stations would that have paid for in that brief period?

(Note that my original comment had misinterpreted the $169 billion as being for each year instead of the cumulative total).

The uptick in coal-fired generation ended in 2013

Coal use was 10 percent higher in 2015 than in 2009 (source: BP statistical review).

…and was more than entirely due to record net power exports (particularly to France) as renewables helped drive German wholesale power prices well below French ones. (Data in German…)

Data in German? Wholesale prices drop when wind or solar create a glut on the market (because it has little value). Exporting that glut to areas without wind or solar is a way to minimize damage to the finances of your own domestic power producers (who have bills to pay).

Beware of the many press reports about German CO2 that confuse the power sector with the whole economy. The notion that Germany substituted lignite for nuclear power or built backup capacity for "intermittent" renewables is nonsense…

Beware of those who want you to believe that German emissions would not have been less had they closed coal instead of nuclear. Roughly 40% of German electricity still comes from coal.

The French Academy's "common-sense" claims are a throwback to the 1990s, ignoring extensive European analysis and experience in achieving high renewable electricity shares (e.g. in 2014, as a fraction of total annual domestic consumption, 46% in Spain, 50% in Scotland, 59% in Denmark, 64% in Portugal) without adding backup capacity or bulk storage, and with superior reliability.

 From the Breakthrough Institute:

When wind oversupply would crush their energy market, they export it to other grids that have little wind. So what happens when those grids have as many wind turbines as Denmark? Denmark won't be able to export it. So, in other words, because Denmark is part of the Nordic Synchronized Area, it isn't really supplying 40% of the energy to that Nordic grid with wind. It's supplying about 10%.

Denmark just happens to use most of that wind because the turbines are located in Denmark and closer to the sources that use their electricity. The game's over once the other countries in their grid get as much wind as they have. And that's the point. They will likely stop wind development far short of Denmark because they don't want to be crushed by their own wind causing oversupply. They will use Denmark wind, i.e., Denmark is only supplying about 10% to the grid it is part of. This is also true for the other countries in your list.

Indeed, the ultrareliable former East German utility 50Hertz in 2015 got 49% of its electricity from renewables, three-fourths of them variable (PV and windpower), and its CEO says it could readily go to 60–70%, still without adding bulk storage.

Indeed …but growth of the non-intermittent renewable sources (biomass and hydro) as well as solar are grinding to a halt in Germany which leaves wind as the only source with much potential for further growth. Note that wind currently supplies only about 2% of Germany’s total primary energy consumption.


John Finnegan's cited blog endorsing certain nuclear operating subsidies is puzzling because it tracks only carbon, not also dollars. It therefore overlooks the opportunity to reinvest a distressed nuclear plant's saved operating cost into several times more energy efficiency (or cheap renewables), thus saving both carbon and money by closing the nuclear plant

What I find puzzling is the lack of evidence that high penetrations of sporadic energy sources decrease the electric bills for citizens. Your above comment rests on the assumption that they do.

 

Nuclear advocates' claim that closing a reactor always means burning more fossil fuel is worth examining but is clearly untrue in Japan, Germany, and even Vermont, where the uptick in gas-burning lasted only a year: NE-ISO's 2014–16 nuclear output loss was 91% offset by renewables and hydro-dominated imports, and another 69% by reduced sales.

Japan? Nuclear output dropped 158 TWh while the combination of wind, solar, hydro, geothermal, and biomass only increased 42 TWh (data per 2016 BP Statistical Review). The increase in renewables did not offset the much greater loss of nuclear. And if the rest is from energy conservation, then clearly reductions would have been even greater had nuclear not been shut down.

Germany? Like I said earlier, beware of those who want you to believe that German emissions would not have continued to decline had they closed coal instead of nuclear. Roughly 40% of German electricity still comes from coal.

Vermont? Your comment about Vermont appears to say that 91% + 69% = 160% of nuclear power was replaced by renewables plus hydro power (which is a renewable) along with reduced sales. But a reduction in emissions from energy efficiency would have existed with or without replacing one zero carbon source (nuclear) with others. Certainly, few nuclear plants can be replaced by hydro and if that is really the case in Vermont, it must have been excess hydro not being used by somebody else already or hydro taken from some other user who has had to replace it with something else, low carbon or not.
Grid integration of variable renewables has at least ten flexibility options, not only in supply but also demand (efficiency and flexibility), and not only in bulk electrical storage but also in thermal storage (in buildings' thermal mass, hot water, cold water, ice), hydrogen, and distributed storage worth buying anyway (such as bidirectional smart-charging electric vehicles).

Why did you say “variable renewables” when you mean wind and solar? And why have these options not scaled up in the decades you have been promoting them? Why will they suddenly scale up a few orders of magnitude in the next few decades just because wind and solar need them? And if they are feasible, why couldn’t nuclear baseload charge all of these storage devices at night when demand is low to minimize the need to run gas power plants in the day, and why haven’t they already capitalized on all of this theoretical profitability already?

Well-designed systems running largely or wholly on renewables will need no added backup capacity and little or no bulk storage…
You are confusing untested hypothesis with facts. And again you said renewables when you meant wind and solar.

…that's the costliest option, so it would be bought last, not first, we needn't wait for it, and the market isn't waiting.

We already know that hydro works without need for backup. Don’t know what you mean by “the market isn’t waiting.” Remove wind and solar subsides and growth would come to a standstill, as happened in Germany with reduction of the solar feed in tariff.

Shellenberger's claim about land use is wildly off.
Your renewable energy footprint paper should be used to teach classes about confirmation bias.

Jon Talton of the Seattle Times writes the ten-millionth uninformed, sensationalist, antinuclear energy article

Antinuclear poster from 2014 Climate March


Below I offer a few thoughts on a mind-numbing article by Jon Talton found in the Seattle Times originally titled Nuclear Energy Fears Exceed Its Benefits.
Among the four words one least wants to hear are “Hanford nuclear reservation emergency.”
Really? Isn’t that a rather sensationalist, not to mention, disingenuous remark? How will assorted pieces of irradiated junk buried in the ground as a result of cold war nuclear weapons production harm anybody not standing in close proximity to it?
At one time, the site had nine nuclear reactors.
Those were devices to produce weapon’s grade plutonium, not to be confused with commercial nuclear power stations. The University of Washington had a nuclear reactor for many years as many large universities still do. A nuclear reactor is not a nuclear bomb or a nuclear power station. The reactor is only the source of heat for nuclear power stations.
But don’t look for a major surge in U.S. nuclear power anytime soon.
There will be quite a surge as the power stations now under construction are completed. At this point in your article you segue from a problem with waste at a military super fund site into commercial electricity production. You have conflated the two for readers who now see using nuclear fission as a heat source for a power station as the equivalent of making material for nuclear weapons. That’s disingenuous and irresponsible in this age of the internet and man-made climate change

Part of the problem was revealed in last week’s Hanford incident.
Actually, waste storage isn’t part of the problem with the building of nuclear power stations. No nuclear power station has been closed because a long term storage facility isn’t available yet.
Inside the collapsed tunnel was radioactive waste buried inside rail cars, no doubt some of it from Hanford’s reactors. The same issue applies to modern commercial reactors. They haven’t released carbon into the atmosphere, but they have left 75,000 metric tons of spent fuel in the United States alone.
Except used fuel from commercial nuclear power stations isn't buried in train cars a few feet underground. The commercial nuclear power station located on the reservation has nothing to do with the military waste stored there. Long term storage facilities for used nuclear power station fuel are being built by other countries and two have already been built here but are not used for storage of that fuel yet thanks mostly to antinuclear lobbyists. You phrase the amount in a manner that makes it sound huge. Spent nuclear fuel is very heavy but takes up very little space. See Figure 1 below to get a feel for that:
Figure 1

And that waste can be deadly for 250,000 years.

Which Electric Car Would you buy, Bolt, 2018 Leaf, Model 3, Model S, or Model X?

Bolt, Leaf, Model 3, Model S, Model X (Tesla images via Next Big Future)
Cue the Sesame Street song, "One of these cars doesn't belong here." That would be the Model 3, of which, none have been delivered. Is it just me, or do the Tesla's all look like they all came from a storyboard for a James Bond movie?

My Leaf's range is approaching the point that it will no longer meet my minimum criteria, which is to get to Everett or Renton from Seattle on a cold day without need to hit a fast charger.

Musk and Trump share at least one thing in common, ah, make that two things: both are quite wealthy, both are consummate salesmen. Musk's Battery Wall pitch a few years ago was near total BS. His purported game plan has been to use the profits from his high-end sports and luxury cars to fund the development of an affordable electric car for the masses--the Model 3. But, I've been driving an affordable electric car for almost six years now.  Lots of car manufacturers beat him to that punch. The Chevy Bolt also beat him to the punch, and the new Leaf, with similar range as the Bolt, may beat him to the punch again.
