Can Solar & Wind Fix Everything (e.g., Climate Change) with a battery break-through?

Where did the money go you ask? Same place where it always goes. Pockets of the "Sponsors". For every $1 invested in a politician, its thousands of profit. (and while the article talks mostly about D's, they are all in on it)



When asked why, Massie explained that the military-industrial complex thrives on the sale of "deadly munitions," which enriches shareholders, "some of whom are congressmen."

"But you gotta wonder like, why is the leadership of your party, the Republican party, in favor of this? Why the new speaker — seems like a nice guy but also like a child — why would his first act as speaker be to endorse this? I’m confused," said Carlson.

To which Massie replied: "Well, I hope he doesn’t. But you know, Biden’s budget director, the head of the OMB sent a letter yesterday to Speaker Mike Johnson, imploring him to spend more money in Ukraine. And what they said is they want to revitalize our defense industrial base."

"And they sent a list of states that would get money when we spend, you know, money on deadly munitions because they have to be manufactured in Alabama or Ohio or Texas," Massie continued. "And so, you know, they’re saying the quiet part out loud that congressmen tend to vote for this stuff because a lot of this federal spending that goes to Ukraine is actually laundered back to the military-industrial complex. And in some ways, not very efficiently, but in some ways, it enriches people in their districts and the stockholders, some of whom are congressmen."

The two also discussed US Under Secretary of State Victoria Nuland and her influence in Ukraine, with Carlson calling her "the single most consequential voice" in the Ukraine debate.

(Nuland's husband, Robert Kagan, notably penned a 'Trump Dictator' piece in the Washington Post last week)

Carlson notes that she was a "driving force behind the war in Iraq, which was of course a disaster and hurt the United States," and now "she has far more influence on it than the entire United States Congress put together."

"How do we allow unelected lunatics like 'Toria Nuland who clearly hates the United States, and always has, to have this power over our lives and our childrens' future?"
Corruption to the core.
 
Some article said he bypassed his BMS to get more power.
When he hit the regen from 40+mph he probably overcharge the battery then it went poof.
Nah, he said it was brand new, and he was out for his first ride. It was not charging when the fire happened. It was spontanious.

Doesn’t that bike have regen?

Stopping from 40+ mph should put juice back in the battery.

Embarrassed Experts Flip-Flop, Now Warn: “Will Snow More Heavily In Coming Years”!​

Much of Europe has been hit with cold temperatures and heavy snow falls so far this month, taking Europeans by surprise. “Experts” blame warming.

Not “a thing of the past”

Don’t be surprised by all the surprise. After all, global warming-obsessed climatologists and media told us back in 2020 that snow and frost would be rare – a thing of the past!

Now with the heavy, record snowfall, global warming astrologists are looking a bit foolish and embarrassed. Their predictions are wrong. Already in November snow arrived and record amounts have already fallen, like in Munich. This has sent the media scrambling for an explanation, and they have concocted one, reports German news magazine FOCUS. Here’s the explanation:

Experts agree: Heavy snowfall is a sign of climate change!”
Strange how whenever there’s a winter with very little snowfall, that too is a sure sign of climate change. And when there are a couple of years of drought, it is the new climate normal. But when there’s too much rainfall, that too proves the climate is warming. No matter what happens, it’s a sign of climate change!

Snow now means it’s getting warmer

In a “fact-check” on ARD German national public television, Ms. Gudrun Mühlbacher of the German DWD national weather service basically said:

The opposite is true, say experts. Rather, they say, the snow is a sign of climate change: snow is becoming rarer, but when it does snow, it is heavy. One reason: due to global warming, it rains more, especially in the fall and winter. The completely rainy November confirmed this.”
More heavy snowfalls ahead!

FOCUS then goes on to explain precisely how our climate works, noting how important it is to distinguish between “climate” and “weather”. “Snowfall does not disprove global warming,” says Melania Botica from the Weather Channel.

“According to climate researchers, the atmosphere can absorb seven percent more moisture for every one degree Celsius increase. More moisture in the air also means more precipitation in the long term,” FOCUS writes. “In the fall and winter, this moisture is released in the form of heavy rainfall or snowfall.”

While climate scientists told us snow would be rare in the future, FOCUS and other German media outlets now report:

It will snow more heavily in the coming years.”
Yet at the same time, the DWD’s Gudrun Mühlbacher says “there will be 65 percent fewer days with at least three centimeters of snow cover at lower elevations.” For Oberstdorf in Bavaria, “it will, however, continue to snow in the coming years, sometimes even more heavily. And this is apparently also due to climate change.”

Junk science at its finest. No wonder Germany’s PISA results are plummeting. You can see it, especially in journalism.
 
Remember those Lazard number that Svetz loved to mention on this tread:
Well, now someone finally did due diligence (not at all surprising)



Lazard’s LCOE​


Lazard’s levelized cost of energy (LCOE) is cited on the internet all the time as the source for “solar and wind are cheaper than fossil fuels.” They don’t really mean “energy,” they mean “electricity.” The world consumed only 18% of its energy in 2021 as electricity, so LCOE is just the cost of 18% of our total consumption, a fact often lost in these discussions.

However, just a quick look at their data shows that solar and wind are clearly not cheaper. Even within their April 2023 report they are not consistent in their numbers. To make matters worse, they bury critical details in the fine print and do not define their terms. I doubt some of their numbers, but for this discussion I only use the numbers in their report.


Figure 1 is based upon Lazard’s chart on page 8. This is the chart where they try and include the costs of backing up the intermittent nature of solar and wind power generation. The chart is complicated and poorly explained, so I’ve added some clarifying annotations. Solar does not work at night or on cloudy days and wind obviously doesn’t work if there is no wind, some sort of backup (“firming”) is needed for when the Sun isn’t shining, and wind isn’t blowing.

Figure 1. Lazard’s page 8 with clarifying comments. To view full size, click here.


They examine four scenarios, labeled “MISO,” “CAISO,” “SPP,” and “PJM.” They do not explain what these cases are, but I assume they are from specific electric utility companies. The graph shows the cost of Lazard’s unsubsidized LCOE in black, their subsidized cost is in light blue, and the backup or “firming” cost is in beige. They do not specify the backup duration for natural gas, but the specified outage time planned for the Lithium-Ion battery case (CAISO) is only four hours. Windless periods are usually at night and in the winter, when it is dark over 12 hours a day, so I have no idea where “4 hours” came from.

The units on the chart are $/MWh (U.S. dollars per Megawatt-hour). The units for the assumed backup cases in the fine print (see note #1) are kW-mo (kilowatt-months). This is probably to confuse the reader; I can think of no other reason. There are 730 hours in a month and 1,000 kW in a MW, so the conversion is x730 and then divide by a thousand. The figure does the conversion for you.

Notice the Lazard figure specifies a range of LCOE from $39-$101 per Megawatt-hour for Natural Gas Combined Cycle power generation. Yet, in the fine print, they specify that the “Natural Gas CT” backup assumptions for solar and wind (used in MISO, SPP, and PJM) are from $6 to $7.45 per Megawatt-hour. They do not define “Natural Gas CT,” but I interpret it as conventional natural gas power generation. Conventional natural gas plants are cheaper than combined cycle, but less efficient.

How is it that the cost of “Natural Gas CT” is a sixth or less of the cost of natural gas LCOE, when used to back up solar and wind? Can anyone clarify this? I’m no expert, but this looks like disinformation to me. In figure 1 the Natural Gas CT cost, only when used to backup solar and wind, is shown as a red line. It is much, much cheaper than the solar and wind costs provided, whether they are subsidized or not. Since wintertime is when solar and wind fail most often, and it can be for days at a time, batteries are clearly ineffective as a backup. Besides batteries fail most often in wintertime also, as anyone who drives a car knows. If we are using this magical and mysterious “Natural Gas CT” power plant at $6/MWh to back up much more expensive solar and wind, why bother with the solar and wind?
 
True but if he messed with BMS could have over charged 1 cell and started it all.

If all cells are in series, and you draw current out to accelerate or climb a hill, then push current back in by slowing or descending, no cell will get more Ah in it than you started with.

Only if you had an active balancer (imbalancer?), pulled power from the pack and charged that cell more, or pulled power from high cells and charged the pack more.

If you over-discharge cells, does that ever cause bloating and venting?
How about discharging at excessive rate, causing overheating and failure?

Oslo’s E-Bus Fleet Could Use Some Warming…City Paralyzed as Buses “Break Down” Due To Cold​


This site here reports that Oslo, Norway’s new electric buses didn’t fare very well during the recent cold. The capital city’s public transport ended up “paralyzed”.

The buses were advertised to have a range of 250 km…but then reality hit!


“Oslo’s brand new fleet of electric buses is not designed for these temperatures – their batteries are failing miserably in the icy cold,” reports aussiedlerbote.de/.

100 million euro fiasco

The city of Oslo took delivery of 183 new electric buses last April with the aim of becoming “emissions-free”. But instead the city has become mobility free. What looked good on paper, didn’t work out well in reality.

“The range of the electric buses decreases drastically in the cold. The batteries run out more quickly,” according to sources. “…with the onset of winter, the weaknesses of the electric vehicles are becoming apparent: although a range of 250 kilometers is actually advertised, the buses sometimes simply break down.”

It’s reported that the contract volume for the buses was 100 million euros.

Cheaper, but doesn’t work

According to Reuters here, last year, Sirin Stav, “Vice-Mayor responsible for environment and transport,” said the buses would “save the city money over the long term” and: “The maintenance is cheaper, it’s also cheaper for the operators of the electric buses.”

“All in all, this is a win-win situation,” Stav added, and so “encouraged other cities to follow Oslo’s example.”

After these recent wintertime performance results, that definitely will be a hard sell.
 

Climate Advocacy: Incompetence Or Intentional Fraud?​

It’s the question that must always be front and center in your mind when you read anything generated by advocates of energy transition as a supposed solution to “climate change”: Is this just rank incompetence, or is it intentional fraud? (The third possibility — reasonable, good faith advocacy — can generally be ruled out in the first few nanoseconds.). As between the options that the advocate is completely incompetent or an intentional fraudster, I suppose it would be better to be merely incompetent. However, often the misdirection is so blatant that it borders on impossible to believe that the author could be so stupid as to actually believe what he or she is saying.

So let’s apply this inquiry to a piece that has come to my attention in the past few days.

From euronews.green we have a piece from November 12 with the headline “Powered by wind and water: The Canary Island proving it is possible to run on renewables.” The byline is Lauren Crosby Mendicott. Ms. Mendicott announces the exciting news that one of Spain’s Canary Islands, El Hierro, has recently reported that it ran its electricity system entirely on wind and water power for 28 consecutive days. Excerpt:

The smallest of the Canary Islands has achieved a record of only using wind and water power for 28 consecutive days. . . . [T]he 1.1 million-year-old volcanic island is on route to being 100 per cent energy self-sufficient through clean, renewable sources. Its 10,000 inhabitants and local government are equally committed to the sustainability of the island.

Wow, that’s great! But OK Lauren, tell us more. If the system ran on just wind and water power for 28 days, what happened on days 29, 30, 31 and thereafter? Can we expect that with just a few tweaks the system can get to running 365 days a year on its wind/water system without fossil fuel backup? Or is it in fact nowhere close to that goal? Unfortunately you will not find any information on those subjects in Ms. Mendicott’s piece.

As readers here know, I have been somewhat focused on the El Hierro project for several years, because it is the closest thing in the world to an attempt to build a demonstration project to show that wind power combined with energy storage can create a fully-functioning electricity grid without fossil fuel backup. I have had numerous pieces over the years dealing with the results of the El Hierro project, most recently this one on September 30, 2023. My conclusion from the data available at that time:

The Gorona del Viento project (wind turbines and a pumped storage reservoir) on El Hierro Island off Spain fails worse and worse every year.

The El Hierro system has wind turbines and energy storage from a pumped hydro system with nameplate capacity seemingly well in excess of peak electricity usage on the island. So theoretically they should have no problem getting all of their electricity from the wind/storage system — right? And yet, when you look at their annual data, somehow they only seem to average about 50% of annual electricity from the wind/storage system. Sometimes it gets to 70% or so for a few months, but then at other times it drops back to as little as around 30%. When I visited the Gorona del Viento website back in September, I found data for what it claimed as hours of operation on “100% renewable” generation for the years 2018, 2019 and 2020 — and nothing thereafter. For some reason, they had stopped reporting these data after 2020. The numbers were 2300 hours in 2018, 1905 in 2019, and 1293 in 2020 — a rather precipitous ongoing decline. Given that there are 8760 hours in a non-leap year (24 x 365 — likely beyond Ms. Mendicott’s math skills) these numbers represent shockingly small percentages of the annual operation of the system, declining from 26.3% in 2018 to only 14.7% in 2020 (a leap year with 8784 hours).

Going back to the Gorona del Viento web site today, I find the same figure of 1293 hours of “100% renewable” generation for 2020, and no subsequent data. Maybe those data are lurking somewhere in the Spanish-language portions of the site where I can’t find them. But somehow I think that if they had some great news to report on that subject, it would be front and center.

El Hierro is blessed with a rare near-perfect site for a pumped-storage hydro facility, with a volcano rising nearly straight up from the sea and a big crater on the top to store the water. Here is a picture of the shoreline, with the mountain rising nearly perpendicular out of the water:

image-37-3.jpg

And yet, despite having such a rare near-perfect site for a large pumped hydro storage facility, the El Hierro system does not have nearly the energy storage needed to provide full-time electricity from the wind/storage system. It would need to multiply its storage capacity by at least an order of magnitude to come close to 100% electricity from this system. Meanwhile, most of its electricity comes from a backup diesel generator — a fact nowhere mentioned in Ms. Mendicott’s piece.

So, is the piece mere incompetence, or intentional fraud? Several factors would seem to give strong support to the inference of intentional fraud — failure to mention the diesel backup at all; failure to mention the number of hours in each recent year where the diesel backup had to be called into activity to keep the lights on, and whether that number of hours was trending up or down; failure even to consider how much energy storage would be needed to enable the system to operate full time without the diesel backup, and whether there are any plans to provide that amount of storage or at what cost. Is it possible that someone could write a piece on this subject without even being aware of these issues? You be the judge!

Let em build a small nuke plant, and they would be fine.
 
More on Lazard LCOE that Svetz was posting here


'Now, consider the question of whether cost figures in the Lazard Report are the result of rank incompetence versus intentional deception. Could the people at Lazard who produce all these fancy and complex charts and graphs really not know that 4 hour duration batteries cycling once per day are not going to come close to solving the intermittency problems of wind and solar generation? Or do they really know that, and they are just hoping to sell a few hundreds of billions of dollars worth of wind turbines and solar panels before the stupid politicians and investors figure out the scam?
