Here’s something the Biden administration and CA Gov. Gavin Newsom haven’t talked about: electric cars actually emit more soot and particulate matter than their gas-powered counterparts—because of their tires. //
the WSJ writers argue that tire wear from the far-heavier EVs is more contaminating:
Where do most particulate emissions attributed to cars come from? California speaks as if their primary source is the tailpipe. That was true in the past. But today most vehicle-related particulate matter comes from tire wear. Cars are heavy, and as their tires rub against the road, they degrade and release tiny, often toxic particles. According to measurements by an emission-analytics firm, in gasoline cars equipped with a particle filter, airborne tire-wear emissions are more than 400 times as great as direct exhaust particulate emissions.
Officials in Sweetwater say an out-of-state company has made their town a dump for the seldom-seen trash created by renewable energy.

Update, September 25: General Electric filed a lawsuit last week claiming that Global Fiberglass Solutions has failed to fulfill its promise to recycle thousands of blades. GE says it paid the company $16.9 million to recycle about five thousand wind turbine blades, but that GFS instead stockpiled them at facilities in Sweetwater and Iowa. “Only after GFS took millions of dollars from GE, did GFS all but shut down its operations without recycling the Blades,” reads the complaint, filed in U.S. district court in New York.
Simply put, these huge industrial sites – we simply must stop using the friendly-sounding term “farms” to describe them – create all manner of negative consequences for local communities. Consequences like loud noise from wind turbines, hundreds of dead birds and bats sprinkled across the countryside, thousands of acres of productive farm or ranchlands taken out of production for many years if not permanently, spoiled views, enormous “graveyards” filled with 150-foot blades and solar panels popping up all over the place, and impacts to local wind and weather patterns that are only now beginning to be understood. //
One West Texas "blade graveyard" alone contains thousands of used blades; these blades cannot be reused, nor can they practically be recycled. Another graveyard, this one in Newton, Iowa, contains a similar eyesore. One of the companies that manufactures the blades, Global FIberglass, has pledged to find a way to begin recycling the blades, but this has not yet happened—and the blades continue to pile up. //
It's all energy density; it's always energy density. To maintain a modern, technological society, like ours, requires greater energy density, not less. The federal government should be held to account; the Energy Department should, at a minimum, stop subsidizing these boondoggles (and, ideally, should be defunded and disbanded). Our society depends on abundant, cheap, high-density energy. //

One of the links in this article brings you to an article that I think is well worth reading in its entirely. I found it eye-opening as to the waste going on with windmills:
https://www.texasmonthly.com/news-politics/sweetwater-wind-turbine-blades-dump/
In Google Maps, I found the dumping ground located in Sweetwater, Texas but, inexplicably, the aerial view had been doctored to make most of it look like raked dirt, poorly doctored yet detectable. Here it is, and you can compare it to the unretouched image in the linked article:
Giving society cheap, abundant energy ... would be the equivalent of giving an idiot child a machine gun. -- Paul Ehrlich
It'd be little short of disastrous for us to discover a source of clean, cheap, abundant energy because of what we would do with it. -- Amory Lovins, 1977
A new paper in PLOS ONE, “Land-use intensity of electricity production and tomorrow’s energy landscape 2”, examines the land use requirements of various alternative energy sources. The paper is open access with the full text available at the link or as a PDF file 5. The results are summarised in the following graphic.
The global energy system has a relatively small land footprint at present, comprising just 0.4% of ice-free land. This pales in comparison to agricultural land use– 30–38% of ice-free land–yet future low-carbon energy systems that shift to more extensive technologies could dramatically alter landscapes around the globe. The challenge is more acute given the projected doubling of global energy consumption by 2050 and widespread electrification of transportation and industry. Yet unlike greenhouse gas emissions, land use intensity of energy has been rarely studied in a rigorous way. Here we calculate land-use intensity of energy (LUIE) for real-world sites across all major sources of electricity, integrating data from published literature, databases, and original data collection. We find a range of LUIE that span four orders of magnitude, from nuclear with 7.1 ha/TWh/y to dedicated biomass at 58,000 ha/TWh/y. By applying these LUIE results to the future electricity portfolios of ten energy scenarios, we conclude that land use could become a significant constraint on deep decarbonization of the power system, yet low-carbon, land-efficient options are available.
“The search for geologic hydrogen today is where the search for oil was back in the 19th century—we’re just starting to understand how this works,” said Frédéric-Victor Donzé, a geologist at Université Grenoble Alpes. Donzé is part of a team of geoscientists studying a site at Bulqizë in Albania where miners at one of the world’s largest chromite mines may have accidentally drilled into a hydrogen reservoir.
The question Donzé and his team want to tackle is whether hydrogen has a parallel geological system with huge subsurface reservoirs that could be extracted the way we extract oil. //
It turned out that over 200 tons of hydrogen was released from the Bulqizë mine each year. Donzé’s team went there to figure out where all this hydrogen was coming from.
The rocks did not contain enough hydrogen to reach that sort of flow rate. One possible explanation is the hydrogen being released as a product of an ongoing geological process called serpentinization. “But for this to happen, the temperature in the mine would need to reach 200–300 degrees Celsius, and even then, it would not produce 200 tons per year,” said Donzé. “So the most probable was the third option—that we have a reservoir,” he added. //
Bulqizë was entirely different. The gas pushed out of the Bulqizë mine is 84 percent hydrogen, one of the highest concentrations on record. Moreover, the hydrogen was not dissolved in water—it bubbled through Bulqizë’s underground pools, making them look like a jacuzzi. //
So Donzé’s team got busy looking for such places, and they found one. “There is a mine in Ural, central Russia, that has the exact same geological configuration as Bulqizë: harzburgite, dunite, and chromite,” said Donzé. “And guess what. They have a problem with explosions.”

One of the reasons I like nuclear energy is its small land footprint.
This video shows the amount of land required by the Olkiluoto 3 nuclear power plant in Finland compared with wind power.

The Hydrogen Ladder is my attempt to synthesise all the information known to me about all the factors driving technology uptake across all sectors of the economy in all countries of the world. Not ambitious at all!
What the Hydrogen Ladder is designed to do is to show how likely it is that any proposed use case ends up being a significant user of hydrogen (perhaps via one of its derivatives) in a decade or so, say 2035. That doesn't mean it's game over, the transition has happened, it just means it is absolutely clear by then that hydrogen is either the answer, or a major answer, to decarbonizing that use case.
In other words, it looks forward to a time after the current firehose of subsidies has subsided to affordable proportions, after there has been enough time for a bit more tweaking of technologies, after the emergence of supply chains, after a bit of familiarity has grown in the project finance sector, and so on.
As for what the rows mean, here's how I think about them:
- A - no alternative (though this does not mean the use case is growing)
- B - decent market share highly likely
- C - some market share likely
- D - small market share plausible
- E - niche market share possible
- F - niche market share in some geographies possible
- G - the Row of Doom
The Hydrogen Ladder is not all about efficiency, as its detractors claim. It does not include information about market size. It does not include information about speed of adoption. It does not include information about relative emissions reduction per kg of hydrogen or kWh of electricity. I leave it to others to add that information to the discussion.
Conversely, it does take into account cost, safety, convenience, critical mineral availability, co-benefits, externalities like air pollution, geopolitics, human behaviour and - underlying it all - thermodynamics, physics, chemistry, other sciences and economics.
The booming sound you may be hearing right now -- especially if you live in San Francisco or Washington, D.C -- could be resulting from liberal heads exploding as they read about what Toyota Chairman Akio Toyoda said during a conference this month. Electric vehicles will only ever make up 30 percent of the market or less, he argued, and politicians should get out of the way and let the markets decide which cars are preferable to consumers. //
No matter how much progress BEVs [Battery Electric Vehicles] make, I think they will still only have a 30 % market share . Then, the remaining 70 % will be HEVs , FCEVs , and hydrogen engines. And I think engine cars will definitely remain.
I think this is something that customers and the market will decide, not regulatory values or political power. [Bolding and underlining theirs.]
That's why Toyota Motor Corporation, which is competing all over the world, has a full lineup of multi-pathway products.

Hydrogen molecules are the smallest in the universe, making it very difficult to make effective seals. First strike.
Hydrogen has an extremely wide flammability range, 4% to 76% of air. Strike two.
While the molar energy density (per molecule) and energy density by weight of hydrogen are exceptional, its volumetric energy density is extremely low, even in liquid form. Compare the size of hydrogen tank to the size of the oxygen tank in the space shuttle. That's one of the primary reasons the SpaceX Super Heavy and Starship rockets use methane instead of hydrogen, because the volumetric energy density is orders of magnitude greater. Strike three.
The Hydrogen energy economy is just another government boondoggle like Solyndra. Attractive on the surface, and sounds intelligent, but ultimately impractical and wasteful.
It's funny actually, if not ironic, that the volumetric energy density of hydrogen is so poor, but as soon as you combine it with some other element, say carbon, its volumetric energy density and practical usability go off the charts! I'm sure some commercial enterprise will discover this and exploit it real soon, and I'm willing to wager that it won't take any government money to build an absolutely booming economy out of it either!!
Just skip the hydrogen! If you're not going to exploit the most efficient energy store in the universe by using a hydrogen compound (hydrocarbons), why do you want to use only half of it, the hydrogen alone?
One should not too quickly dismiss what several generations of the most brilliant minds have already developed and streamlined into an efficient system with sophomoric thinking that somehow believes is an overlooked insight into the fundamentals of the universe.
What is being overlooked is the fantastic energy available from fissioning atoms. The most powerful chemical reaction generates 9 electron volts of energy per molecule. The energy from the fission of one atom (of which there are at minimum three in any chemical reaction) is almost 2 million electron volts. We know how to safely harness an energy source that is six orders of magnitude more powerful than any other, and yet it is rejected. You have to ask why.
"What about the nuclear waste?" It's not waste, it is used fuel, and it can be reused, except that Jimmy Carter, who calls himself a "nuclear engineer" although he never completed the Navy nuclear school, decreed that reusing spent fuel was too dangerous.
Consider too, that nuclear power plants are the only source of energy that completely contain all of their waste/byproducts. The used fuel from all of the nuclear power plants in 70 years of operation in the United States would not fill one single Walmart store.
Annual fuel use for one reactor is 35 tons of uranium fuel -- one semi truck load, although it would only fill a couple of milk crates. The same size coal power plant requires 100 coal cars per day.

Thank you for the compliment. I'm a missionary radio engineer that manages diesel generators and some solar plants because of poor energy supply in Africa.
I've been reading about and studying "renewables" and energy most of my life; I've come to the conclusion that most of the world's leaders are at the energy sophomore phase I was at in high school. Will they ever grow up? Doubtful, to be honest.
If you want a really well-rounded perspective on the whole energy and environment picture and not just the hot takes, read Michael Shellenberger's Apocalypse Never. Fantastic book, and hard to put down! His website is http://environmentalprogres... and is the only thing I've ever seen come out of Berserkely that I could whole-heartedly support. =)
[Edit: I should also give a shout-out to David MacKay's Sustainable Energy -- Without the Hot Air, available on Amazon and online at http://www.withouthotair.com. There is not a better "whole picture" view of energy use out there. ]
One of the best nuclear reactor designs was the Molten Salt Reactor, built and tested at Oak Ridge National Labs from 1965-1969. Thorcon Power wants to mass produce this proven design on a ship-yard assembly line. If CO2 emissions are an existential threat, then we need to be building one hundred 1GW nuclear power plants per year.
A molten salt reactor doesn't need to exchange fuel when the fission product isotopes start to poison the reaction, because the worst poisons ("neutron eaters") are noble gases, and if your fuel is liquid, they can easily be removed instead of being trapped in a solid fuel pellet. So instead of 35 tons of fuel per year, it would only need 1 ton of nuclear fuel per year, and it would extract at least 30% of the potential energy instead of 1%, like the typical Pressurized Water Reactors (Boiling Water Reactors are similar efficiency).
Besides Thorcon's website, visit http://www.daretothink.org to learn more about Molten Salt Reactors; I recommend starting with the "Numbers" page. //

"Hydrogen has its own problems"
Yes, yes it does. It may have the highest energy per molecule, but it is also the smallest molecule, making it very difficult to seal. It also has the worst volumetric energy because of its low density. It's funny how combining it with a couple of carbon atoms fixes that! I wrote a long comment about this the other day on Ward Clark's article about hydrogen.
What would really be interesting, and I think is being ignored for obvious reasons, is hydrocarbon fuel cells, combining the simplicity of the electric drive train with the efficient energy storage of hydrocarbons. It also makes it very easy to make it a hybrid, and if we're wanting to improve efficiency and lower emissions, every vehicle should be a hybrid to recover braking and downhill energy. But hybrids with internal combustion engines add significant complexity.
Fossil fuels are the dirtiest and most dangerous energy sources, while nuclear and modern renewable energy sources are vastly safer and cleaner.
“The elevated costs associated with EVs persisted. Efforts to wrestle it down proved to be more challenging.” //
Because of low demand and high repair costs, Hertz Global Holdings Inc. will sell 20,000 electric vehicles (EV), one-third of its EV fleet. //
Hertz and everyone else had to know this would not work. You mean you couldn’t tell no one wanted to rent EVs?
Go woke, and you waste a ton of money:
Hertz will record a non-cash charge in its fourth-quarter results of about $245 million related to incremental net depreciation expense. //

Recent article by younger fellow discussed how after 7 years his Tesla S had lost 32 percent of it’s range. What was more amazing to me was that he said he would still purchase another one.
Oh, and a 7 year old internal combustion engine vehicle is likely to get the same miles per gallon today as it did when new.
The long-term damage to the economy demanded by the “must go all electric” crowd will just increase. Electrification of everything to save the planet is a canard for being able to completely control humanity.

The easy answer... There is NOT enough electric generation (or power grid capacity) available to replace the power used by gasoline vehicles.
1 gallon of gas = 33.7kWh of power.
The US uses 134,830,000,000 (yes, 134 Billion) gallons of gasoline/year.
4,543,770,000,000. 4.543 Trillion kWh of electricity.
In 2018 we used 3,900,875,000,000 or 3.900 Trillion kWh of electricity.
In other words we need the ability to generate well over TWICE as much electricity (8.4 Trillion kwh) as we currently generate just to stay even.
Add the range and power of semi's and locomotives and ships fueled by diesel and we are WAY, WAY short on our electric generation needs.
The president of the 28th United Nations Climate Change Conference (COP28) seems like an odd man for the job of creating more climate hysteria and trying to end our use of fossil fuels before we have fully developed the technologies to replace them.
His name is Sultan Al Jaber, and he’s the chief executive of the United Arab Emirates’ state oil company, Adnoc, which “many observers see as a serious conflict of interest.” You think? //
Al Jaber responded to badgering questions from an interviewer :
I accepted to come to this meeting to have a sober and mature conversation. I’m not in any way signing up to any discussion that is alarmist. There is no science out there, or no scenario out there, that says that the phase-out of fossil fuel is what’s going to achieve 1.5C…
Please help me, show me the roadmap for a phase-out of fossil fuel that will allow for sustainable socioeconomic development, unless you want to take the world back into caves. //
I don’t think [you] will be able to help solve the climate problem by pointing fingers or contributing to the polarisation and the divide that is already happening in the world. Show me the solutions. Stop the pointing of fingers. Stop it. //
A phase-down and a phase-out of fossil fuel in my view is inevitable. That is essential. But we need to be real serious and pragmatic about it. //

I got a good laugh out of this.
For a very interesting and somewhat new take on global warming, I suggest doing an internet search on:
Paper by William Wijngaarden (York University, Toronto) and William Happer (Princeton); Carbon dioxide saturation effect
A world-class radiation physicist (Happer) finds that the possible effects of H2O and CO2 are saturated, in other words, adding more of them won't heat the planet. //
NuScale is the second major U.S. reactor company to cut jobs in recent months. //
Many in the atomic energy industry are betting that small modular reactors ― shrunken down, lower-power units with a uniform design ― can make it cheaper and easier to build new nuclear plants through assembly-line repetition.
The U.S. government is banking on that strategy to meet its climate goals. The Biden administration spearheaded a pledge to triple atomic energy production worldwide in the next three decades at the United Nations’ climate summit in Dubai last month, enlisting dozens of partner nations in Europe, Asia and Africa.
The two infrastructure-spending laws that President Joe Biden signed in recent years earmark billions in spending to develop new reactors and keep existing plants open. And new bills in Congress to speed up U.S. nuclear deployments and sell more American reactors abroad are virtually all bipartisan, with progressives and right-wing Republicans alike expressing support for atomic energy.
The most common argument is that wind and solar power are the cheapest clean energy sources and that nuclear power plants are the most expensive. Taken at face value, it is true that a single solar photovoltaic (PV) panel is cheap, and that a single wind turbine is cheap, while on the other hand, a single nuclear power plant costs billions of pounds. Technically, measured one-on-one, it is correct that wind and solar are cheaper. But is it useful to compare them in this way? //
To understand why people argue that wind and solar power are cheaper, we need to examine the basic economic metric for assessing a generating power plant: the Levelised Cost of Energy (LCOE). This metric provides what is essentially a banker’s number that covers the total amount of power over the lifetime of an energy source, divided by the lifecycle costs over the lifetime of the same energy source.
But there’s a problem: LCOE is a terrible metric for assessing cost-effectiveness because it doesn’t include several crucial factors. For example, it ignores costs and benefits at an energy system level, such as price reductions due to low-carbon generation and higher system costs when extra interconnection, storage, or backup power is needed due to the variable output of wind and solar power.
Crucially, LCOE ignores the value of the plant’s output to the grid. For example, solar plants have a much more attractive production profile relative to wind farms because society needs most of the energy during the day when the sun is shining. So, even though the LCOE of solar power is higher than wind energy, it provides electricity that is more economically valuable. A paper found that ‘An LCOE comparison ignores the temporal heterogeneity of electricity and in particular the variability of VRE [Variable Renewable Energy]’. Therefore, the true economics of power generation can be very different to the ones predicted by the LCOE numbers.
Another issue LCOE ignores relates to different lifespans of technologies. Typically, a 20- or 30-year recovery period is accounted for, but what about when competing technologies last half a century or more? Then the comparison is faulty, as nuclear power plants can generate power for 60 to 80 years, sometimes longer.
Other factors that aren’t considered by the LCOE include:
- Cost of the land required
- Cost to the consumer
- Dispatchability, i.e. the ability of a generating system to come online, go offline, or ramp up or down, quickly as demand swings
- Indirect costs of generation, which can include environmental externalities or grid upgrade requirements
- Additional cost of integrating non-dispatchable energy sources into the grid
- Cost of disposal, which is usually built into the price of nuclear energy but excluded from the price of solar and wind power
- Subsidies and externality costs, such as the costs of carbon emissions
- The cost of backup or baseload power
Intermittent power sources like wind and solar usually incur extra costs associated with needing to have storage or backup generation available. LCOE ignores the cost of this unreliability, which can be as simple as keeping coal-fired power stations running in case they are needed to fire up and meet electricity demand when it becomes less windy or sunny. //
South Korea is our second example. In the mid-1980s the Korean nuclear industry decided to standardise the design of nuclear plants and to gain independence in building them. The country imported proven US, French, and Canadian reactor designs in the 1970s and learned from other countries' experiences before developing its own domestic reactors in 1989. It developed stable regulations, had a single utility overseeing construction, and built reactors in pairs at single sites.
The results were remarkable: between 1971 and 2008, South Korea built a total of 28 reactors. Due to the developments they made in 1989, their overnight construction cost fell by 50%. //
With nuclear energy, waste disposal and decommissioning costs are usually fully included in the operating costs, but they are not accounted for in wind and solar costs. Yes, a single solar panel is cheap. But what about disposing of it? Sadly, they often end up in landfill sites in poor countries abroad, where they leach toxic chemicals. Batteries are currently not recycled, and therefore this is another missing cost. Wind turbine blades face similar issues. And none of these elements will last more than thirty years before they need replacing. What will that cost? //
Oil and gas companies celebrate wind and solar power because they keep fossil fuels in business. Today, wind and solar are backed 1:1 by oil-and-gas-based generators, to fill the gaps when it isn’t windy or sunny, thus keeping the oil and gas industries in demand. In the future, solar purists propose mega storage, which means more batteries, and overbuilding (extra panels) as the solution. These extra costs aren't factored into LCOE. //
What I have tried to do here is trigger a thought experiment by illustrating how complicated these assessments are, that it is not a case of comparing one panel to one plant, and that the LCOE fails on all counts. Ultimately, the full cost of nuclear energy is an upfront investment for a long-lasting, reliable form of energy, which is not the cost people consider when arguing that solar panels and wind turbines are cheaper. Nuclear energy can get cheaper, or it can get more expensive, depending on how it is approached. //
I am of the opinion that we should build everything we need to bring down greenhouse gas emissions and reduce deaths from air pollution. Yet it is clean energy advocates who only like wind and solar power who argue against nuclear energy based on the myth that the latter is too expensive. //
Every time a nuclear power plant is replaced with fossil fuel generation, people die from the resulting air pollution, and more fossil fuel waste is stored in the Earth’s atmosphere. Every time a grid is made to support more wind and solar power without the baseload power to support them, fossil fuels win as they have to fill the gap. Every time a nuclear power plant isn’t built on the supposed basis of cost, the environment is further harmed and human progress takes a step backwards. Every time someone quotes the LCOE, they are either being misled, misleading others, or both.
Last February, the independent Public Advocates Office of the state Public Utilities Commission reported that residential electricity rates in California had risen between 77% and 105% since 2014 and are far above the national average. “The majority of bill increases are associated with long-standing state priorities,” the report explained.
Yet for all the money Californians pay for those “priorities,” the state doesn’t really run on solar and wind energy.
It’s powered mostly by natural gas, hydroelectric, nuclear energy and, when all else fails, electricity generated in other states and imported on transmission lines. //
While California’s need for electricity can rise as high as 50,000 megawatts in the summer with air conditioning, solar energy produces about 15,000 megawatts at its peak, declining to zero after sunset.
The gap is filled by – you guessed it – natural gas, nuclear, hydroelectric and imports.
In pursuit of “100% clean electricity,” the state’s gas-fired plants were scheduled to be closed this week and its one nuclear plant to be shuttered in 2025.
The Center For Alternative Technologies in the UK delves into embedded carbon in residential storage batteries. It says the carbon footprint of current lithium ion batteries is around 100 kg of carbon dioxide per KWH of battery capacity when manufactured in factories that use fossil fuels. When renewable energy is used for the manufacturing, this is reduced to about 60 kg of CO2 per kWh.
