S&P: Chronic Copper Shortages will “Short Circuit” Net Zero 2050

Essay by Eric Worrall

It seems a pity nobody ran some numbers BEFORE making promises and spending billions on an energy transition which we don’t have the resources to make happen.

Copper shortage keep green energy, tech ventures grounded

Copper the balloon popper for 2050 net-zero goals according to S&P

Copper is so central to transitioning from fossil fuels to sustainable energy, says a report from S&P Global, that worldwide demand is likely to double by 2035 from 25 million metric tons to 50; no matter the scenario, S&P said it’s unlikely the world will be able to meet it.

“The record-high level of demand would be sustained and continue to grow to 53 million metric tons in 2050 – more than all the copper consumed in the world between 1900 and 2021,” S&P Global said.

From oil to minerals

In a 2021 report, the International Energy Agency (IEA) described a new energy paradigm slowly replacing fossil fuels – minerals, the most important being copper.

Internal combustion vehicles of all sizes have around 24 kilograms of copper in their powertrains, the report’s data shows. Swapping internal combustion for fuel cells leads to a slight increase in copper, but swapping fuel cells for batteries is where things start to really scale up. A light duty battery-powered EV (BEV) powertrain requires 60kg of copper. A medium-duty BEV requires 139kg, while a heavy-duty BEV needs a whopping 425kg of copper.

The obvious solution to this inevitable problem would be to open more copper mines. That would definitely help offset coming shortages, but the catch is that those offsets would come too late.

It currently takes 16 years, on average, to develop a new mine, meaning that a new mine seeking permission today would not become productive in time to accommodate the demand spike,” S&P said, quoting an IEA study.

Substitution of other metals – like aluminum – and recycling of copper reportedly won’t be enough to meet projected demand either, S&P’s data shows. 

Read more:

The S&P report is available here. The first key finding in the executive summary pretty much says it all; “Copper—the “metal of electrification”—is essential to all energy transition plans. But the potential supply-demand gap is expected to be very large as the transition proceeds. Substitution and recycling will not be enough to meet the demands of electric vehicles (EVs), power infrastructure, and renewable generation. Unless massive new supply comes online in a timely way, the goal of Net-Zero Emissions by 2050 will be short-circuited and remain out of reach.

Obviously it is possible some unexpected advance will dramatically increase copper availability, in the same sense it is possible I’ll win the lottery. But I’m not holding my breath waiting for either event.

Do these estimates of how much copper will be needed include the amount of copper that will be necessary to increase grid capacity by a factor of 4 or 5?

A mountain may seem a lot but the copper content is low. The sulphide ores are always mixed with large quantities of siliceous material or ‘gangue’ and never contain more than 1 – 7% of copper.

Copper smelters generate huge CO2 emissions fouling up the net zero emissions targets. Just as soaring NG costs are forcing the fracking issue and the search for new gas fields in the West. Also where are the mining companies going to find all the Lithium required for EVs; Lithium extraction is not all that environmentally friendly a process. The climate change zealots will go crazy.

Correctio apparently copper smelters do not produce much in the way of Co2 emissions. Depending on the ore the main emission is SO2 which should be easily dealt with to produce H2SO4 . Copper occurs in nature combined with iron and sulphur as copper pyrites or chalcopyrite, CuFeS2.Extraction involves leaching with dilute H2SO4 the the solution is electrolysed in cells fitted with pure copper cathodes. Other copper sulphide ores use melting and reverberatory furnaces.
The crude copper produced by the above three processes must be refined. Thermal refining does produce emissions to reduce cuprous oxide. Copper of the highest purity is produced by electrolytic refining. I should have remembered or known all this having worked in the non – ferrous smelting industry.

It’s not just the copper itself. Where is all the insulation material going to come from as we shut down oil production – meaning shortages of plastics?

Nor is it copper wire that makes up all the future demand. What do printed circuits use for conductor paths and ground planes? As you substitute electrical load for natural gas you increase the control circuits – charging circuits, solar panel control circuits, residential backup battery controllers from solar panels, etc.

The fact is that we have far too many elected politicians and far too many un-elected bureaucrats that know absolutely nothing about the real world. We aren’t governed by “elites” today, we are governed by the “stupes” that can’t do anything productive.

@Duane: In Alberta, where 99.9 percent of hospitals, schools, seniors’ residences, office towers, public buildings, and private residences use natural gas for heating, the grid capacity will have to increase by more than 500 percent. Not only are we supposed to replace fossil fuel consumption with electricity consumption, we’re supposed to replace reliable, high capacity factor fossil fuel generators with 40 percent capacity factor wind and 20 percent capacity factor solar, which would require a massive overbuild in generation capacity and staggering amounts of battery storage.

A new problem with electric cars.

A family bought a used 2014 Ford Focus electric car for their son. The cost was $11,000 and had 60,000 miles on it. The car worked fine for a couple of months then started throwing all kinds of warning lights.
Turns out the car needs a new battery. The battery, at $14,000 costs more than the car did, but that’s not the biggest problem. The car has been discontinued by Ford, and there are no batteries available, at any price.

The insane cost of replacement batteries is a well known problem, but not being able to get a battery at all because the model has been discontinued is a new one to me.

The article didn’t mention it, but something that stuck out to me was the fact the car had only 60K miles on it. Haven’t the various electric enthusiasts been claiming that electrics are so much more reliable and should last many times longer than ICE vehicles?
Here’s another example of the real world not living up the activists hype.

According to several Global Energy Consumption web sites, the total Non-renewable global energy consumption is in the neighborhood of 150,000 TWh. [ Energy is in terms of TWh for simplification and to avoid the use of multiple labels, like BTU, Therm, etc.] That number excludes bio, Solar and Wind. I seriously doubt that the energy used in third world countries in the mud and thatch homes outside of the cities that have electricity are included in these numbers. The only way to achieve the Mythical “Net-Zero CO2” is for all of that “Energy,” 150,000 TWh, is going through Copper wire. Keep in mind that the “Renewable” portion [not included above] is less than is less than 10 percent of that 150,000 TWh is renewable.

Once upon a time a roll of pennies was worth ~$1.00, today they are made of steel. Go to Home Depot, Lowes or any supplier that has copper wire and buy a length of 4/0 Gauge, 0000 AWG, (App 0.50 diameter) copper wire – $10.00. Yes Copper is rarely used in transmission lines, However, when the electricity is on generator or the user side of the transformer it is high grade copper. Aluminum is rarely used. Therefore, that price is going to go to near $100.00 a foot. and all of those Copper mines that Obama put off limits are going to make those nature preserves look like the strip mines of West Virginia.

A few years ago, I read something similar. It said that in order for England to go all electric would take ALL of the world’s current copper production. That’s not the EU, it is just England. It will be a massive shortfall, and we are diving headfirst into it.
Not to mention that it takes ‘fossil fuel’ power plants to charge all these electric vehicles, with the low efficiency at production, and subsequent transmission losses, which can amount to 30% or more. So, MORE power plants needed to meet the growing demand of EVs recharging, but using more expensive energy.
IC vehicles are seriously efficient. There is no way EVs will ever be as efficient as ICVs.

Robert W Turner
Reply to  John Shotsky
July 17, 2022 10:27 am

Losses in the Carnot cycle for EVs occurs at the power plant, transmission, and charging. Losses for ICE occur at fuel combustion in the engine itself. With as efficient as power plants are compared to individual ICEs, EVs are currently a little more efficient than the average ICE but a little less so than a good hybrid.
But this is not likely to persist as the low hanging fruit of lithium production is already all in production. I don’t think we’ll need to worry about copper shortages because there will be shortages in lithium, nickel, cobalt, and silver first.

It’s called Cronyism – it always happens when Government mandates ‘something’ ‘anything’ that requires almost any resource.

The folks supplying whatever the ‘something’ is simply gouge the market. When it is Legal Law that you must buy something like an electric car, the manufacturers set up an informal unspoken cartel and sky’s the limit.
That our politicians haven’t worked it out is quite amazing.

BUT, oh yes they have worked it out.
A career as a politician is invariably quite short and when they get deselected,they join the legions of cronies that they created while they were in power.

It is more corrupt than a really corrupt thing and the system is now so big & convoluted there’s no way to control it and stop that humongous corruption and waste of resources

There is a genuine requirement for a Great Reset.
That ‘reset’ will centre on re-sizing Government down to something where it can actually manage itself – before it then attempts to manage the county/state/country/world.
Heaven forbid such mendacious muppets want to control the weather.

Bring it on, bring on Great Reset
Great Government reset, not a reset of the economy.

Energy-dense stuff is burned to release heat. The heat then boils water into steam, causing a turbine to spin, and that is used to help in generating electricity. Though this is one of the most effective ways of producing electricity, the only ⅔ of the energy produced turns into electricity. The other energy is lost due to the thermodynamic limits in the process.
Different power is lost at different stages

  • 1-2% of energy is lost during the step-up transformer from when the electricity is generated to when it is transmitted.
  • 2-4% of energy is lost in the transmission lines
  • 1-2% of energy is lost during the step-down of the transform from the transmission line to distribution.
  • 4-6% of energy is lost during the distribution

So, the average loss of power between the power plant and consumers ranges between 8-15%.
But burning fuel to produce electricity is not terribly efficient, compared to an ICV. Losses are at LEAST 40%, not counting getting the fuel to the power plant in the first place.
My point is that it takes a LOT of fuel to recharge our growing army of EVs. And it will take a lot more, as that army increases in size. They are fed by this inefficient process, compared to just using gas directly in the vehicle.

re: “Energy-dense stuff is burned to ..”

Redundant and superfluous; why are you repeating this to me? Also, you’re not including nuclear processes, OR wind and solar processes, both of which constitute a good portion of Texas’ energy supply on any given average day.

How about a cite for some of your quoted figures too.

Again, why are you quoting these figures to me? I don’t see your losses mounting up to the claimed 30% loss figure either, unless some slight of hand with numbers was just pulled on us.

Reply to  John Shotsky
July 17, 2022 7:02 pm

Transmission line losses are higher than 2-4%. For a 100 mile high voltage transmission line the losses are about 17%. Distribution losses closer to where the power is used can approach 50%. This includes the step-up/step-down transformers, but it’s still huge.

Charging efficiency of EVs is about 85%. Any heat generated in using the EV is more energy loss. It stands to reason that the discharge efficiency is similar to the charging efficiency…but again, that is using the prime energy of fossil fuel power plants with its already-degraded efficiency.
Some early cars were electric. They found it more efficient to burn gas. Nothing has changed except long-lost lessons are forgotten.
Ignorant people don’t understand that doing things in the most uneconomical way does not help anything, not least of all the climate.
So, burn fossil fuel and distribute it to charging stations at a loss to reduce emissions? Are you joking? It will INCREASE emissions because they have to rebuild the grid and burn more fossil fuel in the process.

Reply to  John Shotsky
July 18, 2022 7:26 am

I thought it was 15% in and 15% out. There’s also the energy consumed by the circuitry that converts AC to DC and manages the charging cycle, and the circuitry that converts the DC back to AC. Not to mention the various wiring losses.
And we can never forget the energy consumed by the active cooling elements that keep the battery from overheating.

When I was a kid in CA, a lot of homes had to hire electricians to rip out the aluminum wires that had been installed when the homes were built and replace them with copper.

Because of aluminum’s higher resistance, the lines would heat up when under load. Over time these heating and cooling cycles would cause the wires to start to come loose from wall sockets or light switches. When this happened, the amount of surface area in the contact region would decrease, which caused even more heating.

A lot of houses burned down because of aluminum wiring.

The Al wire itself is fine (except it can melt at lower temps that Cu, and it burns). The issue was the insulating AlO2 layer that forms almost instantly when the wire is exposed to air. A properly designed and applied connector was fine, but people would use normal connectors, or not apply them correctly, and the outlet/breaker/junction would burst into flame after the insulating layer got to the right thickness.

There were more problems than just using the correct connectors in the proper manner. Again, Al wires need a larger bend radius than copper. An installer that didn’t realize that could cause the Al to eventually crack at a bend Cu could handle fine causing a high resistance and subsequent fire.

There are just a lot of reasons why AL wire isn’t used in house wiring any more.

Aluminum has a higher resistivity than copper. It is usually recommended to use twice the AGW size of copper if you are going to use aluminum. Bending radius is usually somewhere around 8 times the wire diameter so aluminum wire will require a larger bend radius than copper wire with the same power carrying capacity. This makes anything with windings such as transformers or motors much larger if you use aluminum wire.

Copper-clad aluminum is fine for wires carrying high frequency currents since those involve skin effect so the aluminum doesn’t contribute much to carrying hi-freq power. That’s not the case for DC or low freq AC power transmission.

Aluminum wire corrodes much easier than copper, especially when in contact with copper wire. Thus you have to use special aluminum-copper splicing connectors along with corrosion preventive paste.

Aluminum’s main attractiveness is that it is lighter than copper. Thus its use in long span situations such as electric power transmission lines.

From an engineering view I’m not convinced that aluminum can be substituted for copper in most of our usage. It’s another pipedream.

You’ll typically find waveguides in the microwave frequency spectrum. Below 1ghz coax is the main transmission media for RF. The use of copper-clad aluminum would work fine for 500khz to 1ghz. The problem is that copper-clad aluminum in coax has all the problems of aluminum – larger bend radius, lower tension strength (long vertical runs leads to stretching and failure), and connector issues.

Jim Gorman

A slight correction Mark. Waveguides use a different mode of operation as compared to two conductor coax.

Any alternating current in a conductor utilizes only the outer portion of the wire. This is known as the skin effect. I like to think of it as analogous to being a waveguide of sorts.

As frequencies climb into the microwave, skin effect losses become very large and waveguides come into their own. However, the mechanism for propagating the EM wave differs between the two types of conductors.

It is a notable shame that so much copper will end up being sequestered unproductively, and for no good reason, in intermittent wind and solar sources, battery and other storage systems, and low-utilization distribution systems such as for EV charging. All of this was easily anticipated and widely ignored to push the “renewable,” “clean,” “net zero” nonsense.

Copper is just one of many reasons you cannot get to net zero from here, ever.
There is no solution for renewable intermittency except redundant fossil fuel fired backup generation.
There is not enough cobalt and lithium to go to a BEV transportation solution. Nor is there a viable BEV solution for heavy trucking.
There is no way to avoid natgas or coking coal to make the steel for grid pylons and wind towers.
Heat pumps are useless in cold winter climes.

Nuclear is the only current option to replace fossil fuels after fossil fuels run out. The good thing is that we likely have more than 50 years before we run out of natural gas and more than 100 years before we run out of oil as there are still huge amounts of proven oil reserves, shale oil, and tar sands.

There’s still plenty of time to manage the next energy transition in a responsible way but we need to recognize that unreliable renewables aren’t going to do it.

Most economically mineable resources have to be concentrated well beyond their average crustal abundance. There are many geological processes that do that. However, it is life that captures and concentrates carbon and hydrogen, and it has been doing so for at least a half-billion years, and probably about a billion. Life has saved us a lot of energy by concentrating these critical elements.

You think the people that will do this will be able to tell the difference between copper vs copper-clad aluminum?

Melting point for copper is about 2000F and for aluminum is about 1200F. If you can control the temperature closely enough you can melt the aluminum away from the copper but it will probably just make a mess in your kiln. You aren’t going to do it in a bonfire in a barrel.

Usually the bonfire is used to melt away the insulation on the copper wire leaving just the copper.

No. Switch mode designs save ALL the way around (cost, size, weight, even efficiency). For crying out loud, you’re using two or three switch mode power supplies RIGHT NOW to access the internet in your computer, monitor and cableTV modem or iPhone and its accompanying power supply! You just don’t know “tech”!

The recent microwave ovens have done away with the ‘usual’ MOT transformer so THAT SHOULD TELL YOU something about COSTS of these things. Power FETs are cheap, and the ‘science’ behind ferrite materials is now well-known too.

Oh – its MarkW a well-known clown in areas concerning tech, never mind. I might as well be talking to a DOG about PHYSICS. Hey Dufus, at TI we were using 2N5157 bipolar TO-3 cased transistors in an airborne RADAR transmitter power supply in a design dating from the 1980’s … we qualified a production lot of those transistors using a pulse energy test on each transistor at 2 kW peak … again, you don’t know your ‘tech’.

I think you are missing the fact that power is “Voltage * Current” or “I^2 * R”. You can postulate that switching power supplies will reduce the power that needs to be delivered, but it really doesn’t. For example, the lights in your house are going to need say 400 watts total. The power coming in must equal 400 watts. A switching power supply running at say 90% efficiency will need to put out 400 watts and will draw 440 watts. You never get something for nothing.

You also miss the ancillary components required for filtering, toroid transformers, and circuit traces.

It’s also true that all components have both inductance and capacitance. It takes a lot of careful design work to minimize these parasitic effects. You also have to be careful about how your circuit is laid out on the board, since these surface traces can be a major source of parasitic inductance and capacitance at high frequencies.

Who do you think you are trying to fool? Pulsed use is very low heat generation. For power use with appliances, etc you are concerned about *continuous* use.

“you’re using two or three switch mode power supplies RIGHT NOW to access the internet in your computer, monitor and cableTV modem or iPhone and its accompanying power supply! You just don’t know “tech”!”

And those power supplies are NOISE GENERATORS. I know. I’ve tested them with spectrum analyzers trying to run down noise on my power line and in my amateur radio. Put them in a poorly shielded computer and they can even interfere with wifi connections to a smart TV.

Lets add the switch mode is always inherently more prone to failure as a transformer will take a lot more abuse.

Remember the moron public will be plugging into this stuff .. that means they will do stupid stuff like daisy chain twenty power boards and overload the hell out of everything. The size and weight of a transformer usually works in it’s favor it will take the heating while giving a fuse a chance to work.

I use switched-mode power supplies in my amateur radio station. Switched-mode power supplies are NOISE GENERATORS. Ones that are not are *expensive* because of all the shielding and bypassing that is required. They can interfere with wifi connections as well as my amateur radio frequencies. If you use unshielded internet cable and connectors, the noise can get onto your ethernet cables as well. They will *not* be a panacea in residential use. They are likely to cause far more problems than simple copper transformers will.

Because of their complexity switched mode power supplies fail much more often. I have a 35 year old linear power supply as the feed for one of my stations – all I’ve ever done is replace one or two power transistors, cheap and easy to do. I don’t have a switched power supply that is older than five years old. Getting replacement parts has always been a supply problem and manufacturer repair is expensive.

The old simple HVAC system I installed in this house when it was built lasted for 25 years before the furnace burners began to crack and became a carbon monoxide hazard. The newer one I installed has already had to have two circuit boards replaced in the past ten years. Thankfully not expensive but a real pain-in-the-backside when the furnace dies in the winter an you have to go hunt up parts somewhere in town.

BTW, a 75 amp, 13.8v switched power supply will run you about $400 for a continuous duty one – one that is not guaranteed against being a noise generator.

Turns out that overnight someone had somehow managed to steal over 1 mile of 3 inch telephone cable, probably for the copper. They were caught about 6 months later, trying to burn off the insulation from the copper.

There will be an epidemic of missing power cables and components in future years. The more cables and wires we install, the more people will want to take them. Sooner or later, somebody’s going to hit on the bright idea of putting more of them underground where they won’t be obvious and will be harder to get at – it’ll be cost effective if you balance it against stolen or missing cable.

This is a huge rising problem, largely ignored by governments and media, and it’s being more and more of a stone in the shoe for activists. Electric cars are important as copper consumers but aero-generators and solar panels are also important (these latest one consume 11.1 tons of silver for each square km). An offshore eolian tower costs about 67 tons of copper for instance. However, do not forget many other things that are not required in so much quantity but are also an important bottleneck such as neodymium, dysprosium, terbium, germanium, silver, palladium and many others. Probably we will cry in future for the times when oil, natural gas and coal were used to produce energy. We can use these things with much more efficiency and even with much less impact while we cannot figure out how to get a constant, clean, highly available and efficient way to produce energy.

A recent report for the European Commission looked at the combined critical raw materials use in different technologies in the EU in 2030 and 2050. All amounts are x current usage.

2030 2050
Lithium x18 x58
Graphite x4 x14
Cobalt x5 x14.5
Disprosium x5 x12
Neodymium x2 x4
Nickel x1 x3.5
Praseodymium x5 x12

In the case of lithium that is an increase of 108,000 tonnes by 2030 and 348,000 tonnes by 2050. For cobalt an increase of 150,000 tonnes by 2030 and 435,000 tonnes by 2050.

Now imagine the mining needs if the whole world is aiming for net zero in 2050!

The report also noted that the EU currently only provides 1% of the critical raw materials for wind energy.

I don’t have those numbers handy. I do know that when I was growing up – more than fifty years ago, the criteria for opening a new pit was 20+ years of economic production. These days, it is almost certainly 30+ or 40+, and I wouldn’t be surprised if it is much higher. Partially less rich bodies, mostly much higher overhead per ore ton.

Some years ago, I do know that the pioneers in in-situ concentration were estimating 50+ years of operation where they were using that technology.

The mines I grew up near, just a few miles away, were started back between 1906 and 1909 and began producing concentrate between 1911 and 1915. Ups and downs, depending on the economy (particularly wars), but still producing as of this day.

Eric, almost every article I read on mineral resource availability is grossly wrong (I have corrected copper before). I can tell an amateur study by such remarks as

“…grow to 53 million metric tons in 2050 – more than all the copper consumed in the world between 1900 and 2021,” S&P Global said.”

First, 35% of copper consumed is recycled copper, which means that a fair proportion of copper consumed is consumed every year.

Second, the USGS (the best mineral commodity source in the world) reported that existing mines contained resources of 1.6 billion MT in 2015 we apparently need another 25 million MT by 2035. They also did a study based on favorable geology in regions known for their copper mining, estimating 3.5 billion MT yet undiscovered. I have no doubt that we are seeing the beginning of the end of the whole marxist-climate shiteree for other reasons. The mining industry won’t be the bottleneck whatever happens.

On my cell phone I didnt mess with pdf links, but, anyone interested can Google USGS Mineral statistics for their excellent full info preprints for their Annual Minerals Yearbooks. For good summaries they publish up to date 2-3 page annual world summaries.

The copper is only part of the problem. It must smelted and drawn into wire then spun into the correct sizes. To do this in the time frame required will probably necessitate new manufacturing plants.

THEN, the wire must be wound on transformer iron in the correct shape and size plus enclosures, insulators, and miscellaneous hardware. Distribution cable must be insulated. Newer high voltage lines will need larger insulators, with wider spacing on cross arms, new switches and fuse mechanisms. None of this has even been ordered.

This is all a joke and will come crashing down at some point. I have managed some pretty large projects with lots of little pieces. Anyone who thinks the government, Congress or Executive, has the expertise and wherewithal to know where to start is living down a rabbit hole along with Alice!

Almost all copper produced today comes from low-grade porphyry deposits in granitic rocks. It requires huge amounts of energy to obtain the copper, because most of what is excavated is waste rock. Below is a view of the Kennecott open-pit mine in Bingham Canyon, near Salt Lake City. For perspective, the benches are about 40′ high, and the haul trucks have tires >8′ in diameter. See if you can spot any.

Copper mining does considerable environmental damage, raises concerns about ground-water pollution, and it is questionable that trucks of current size or larger can be run off batteries. Therefore, the prospect of ramping up production to meet the increased demand for copper, is not good.

If you believe in perpetual motion machines, then ‘obviously’ the plan will work. However, in the real world, where loaded trucks have to climb a hill, and the empty trucks will go back down, and there will be losses from mechanical friction and flexing of the tires, I think that, at best, it can be used to supplement chargers and reduce the inevitable charging time. An unknown is what the constant charging and dis-charging will do to the longevity of the batteries. One reason that open-pit mines are used is the economics. Battery-powered trucks will undoubtedly change the economics. Somebody needs to do the detailed analysis before we get to the point of no return.

Molybdenum is a big byproduct of many copper mines. Much in demand for high temperature alloys and oil cracking catalysts. (Strangely, also for fertilizers applied to cauliflower fields.)

Rhenium, another byproduct, is valued for much the same reasons. At ~1ppb, it would never be mined for itself, even at a price around $1,500/kilogram. But it pretty much falls out into your hands when you process certain copper ores.

This is just one of very many reasons why net zero will not happen by 2050.
It is a fantasy held by technically illiterate politicians and political advisors.

According to a youtube video posted recently by an EV owner & enthusiast, there’s been an outbreak of thefts of copper cables from EV charging points in the north of England. In one case a car had been left to charge overnight at a dealership, and the cable was cut out between the charger and the car – the battery was fully charged when this happened so charging had stopped; the severed connector was left locked to the car. Repair costs to the charger were said to dwarf the value of the stolen copper.

The sad thing is that for most of these resource type thefts, the cost of repairs is many times greater than the value of what was stolen.
Even if they just steal a roll of cable that was just laying on the ground. The value of the cable, as a cable, is many times the value of the raw copper in the cable.

The conclusion of this report is correct, the increase in required copper for EV’s, and wiring infrastructure to power the chargers for said EV’s is not sustainable. However I challenge some of the numbers used.

Modern ICE powered passenger cars (excluding hybrids) do NOT have 53 pounds of copper “in the drivetrain”. The drivetrain comprises the engine, transmission, differential(s), drive shaft(s), axles and wheels/brakes. Some copper or brass is used in bushings or seals in these components, and a small amount is used in various sensors and in the ignition coils and/or spark plug wires. Let’s put the direct drivetrain copper at 2 lbs.

Most of the copper in an ICE vehicle is in the main wiring loom, and in the ancillary components such as starter motor, alternator, blower motor, wiper motors. Main wiring loom is approximately 5 pounds (I work as an automotive repair tech, and have direct tactile experience with each of these, along with the entire drivetrain)

Starter motor and starting cables are another 5 lbs of Cu. Alternator and blower and wiper motors – 5-7 lbs.

So we have 2 (drivetrain) + 5 (main loom) + 5 (starting) + 7 (remaining motors) = 19 lbs or 8.62 kg of Cu. Lets throw in +25% for contingency, that yields 23.75 lbs (10.78 kg).

Now let’s view a pure electric passenger car:

It still requires the main loom, and the ancillary motors – in fact it requires more than an ICE, because it must have a separate electric motor to drive the air conditioning compressor, and it must have a separate motor for power steering pump, both of which in an ICE are belt drive off the engine. It does not require a starter motor, but the extra motors for A/C and Power Steering, and for brake boosting (ICE engine uses engine vacuum for brake boosting, so an EV either needs a vacuum pump motor, or a bigger power steering pump/motor to provide hydraulic brake boosting) far outweigh the missing starter motor.

And all those extra motors and controls and the drive motor controller, adds to the main loom, approximately doubling it’s weight to 10 lbs.

Then there is the main drive “train” motor or motors. At least 100 to 150 lbs of Cu needed there, and the cabling to deliver the many hundreds of Amps at hundreds of volts, well add another 20 lbs there.

So the EV stacks up as follows:

Drive Train motors 150 lbs
drive train cabling 20 lbs
Ancillary motors 15 lbs
main loom 10 lbs

Total 195 lbs (88.48 kg)

So EV’s need roughly 8 times more Copper than does an Internal Combustion Engine (ICE) powered passenger vehicle.

As I said, the report reaches the correct conclusion on the ratio of Cu needed for electrification of passenger transportation, but the specific numbers are faulty.

Most of the weight an electric motor is the copper windings, and these motors weigh much more than 2 pounds.

Mark W needs to check on some electric motor 101 material! No Mark, most of the weight in almost every electric motor type, is the steel of the armature/rotor and the steel of the stator.

When is the last time you changed a starter motor, or a blower motor, or an alternator in a car? Have you ever taken one apart? How about the last time you designed and built an electric motor from scratch, including laser cutting the rotor and stator steel sheets, and winding the coils?

I have done all of these things, many, many times. Before semi retiring and doing automotive repair to stay active, I ran an R&D lab designing and testing electric motors and generators.

Have a look at the following cutaway of an automotive alternator:

Now the rotor and stator cores are in fact steel, as is the shaft and bearings. the outer case is aluminum, and the copper wire is visible. Breaking down the ratio of the areas and deriving the volume of each materials is as follows:

Steel – bearings/shaft 2 units of volume
– rotor 3 units
– stator 3 units
Total Steel = 8 units of volume, steel density 7.8 , steel mass = 62.4 units of mass

Cu is 2.5 units of volume, Cu density is 8.9, so Cu mass is 22.25 units of mass

Al is 3.5 units of volume, Al density being 2.7 so Al mass is 9.45. units of mass

Clearly the most mass comes from the steel.

Starter motor is similar ratio of steel to copper, and small actuator motors like for cabin air flow, or windshield wipers have lower fraction of Cu to steel, and have an order of magnitude less Cu. you can pick up a blower or wiper motor with one finger, however you need both hands unless you are a gorrilla to lift either an alternator or starter motor.

the notion there is 52 lbs of Cu in an ICE only car is nonsense!

Malarky. I can’t tell you how many car, tractor, and semi-tractor starters and alternators I have installed in my past life as a mechanic. BY MYSELF, no gorilla assistant! And I have undercut the rotors in things like generators – without tools using a broken piston ring to remove the carbon buildup, so I do know how to take one apart and fix it AND put it back together again.

Attached is a cutaway of an EV drive motor and a typical dc motor. There is a huge amount of copper in the motor itself. The steel part of the load comes from the cores (as you note), the mounting shell and and involved gears (if any) in the motor.

Mark is correct, however. EV’s do have much more weight in copper than do ICE vehicles due to the increased size of the motors and ancillary equipment involved.

The Demprogs plan is to order out like everything else while forcing the transition ever onward with no delays allowed.

Aluminum is the third most abundant element in the earth’s crust, but unfortunately it cannot substitute for copper in many places. In the 1970s they tried wiring homes with aluminum and many of them had house fires because aluminum junctions with other metals are not electrically stable.

July 18, 2022 8:26 am

There’s another problem with the transition from fossil fuels to unicorn farts that no one likes to talk about. Homes and businesses that are heated by oil or natgas will be forced to switch to electric heat. This means the electric grid will experience the same strain in the middle of winter that it does in the middle of summer when everyone runs their air conditioners.

Is the Obiden crowd ready to address a sagging national electric grid? (Answer: of course not … they have backup generators fired by the same fuels they want to ban for the rest of us.)

Bought some heavy duty jumper cables because the wire was much cheaper than bulk copper cables. Only to discover the wire was copper clad aluminum. Now know what CCA label means.

Testing with ohm meter shows CCA is not equivalent.

Obviously! These nett zero/climate change idiots have forgotten to ask engineers, and particularly mining engineers, if their wacky dream is at all possible. Apart from needing to increase copper production for electric vehicles, more copper (and aluminium) is needed for new transmission lines, copper for car chargers, copper for new wiring in houses and apartments, etc. And then there are the other metals that are in the same box. How much more lithium? I read in the past week that Bolivia is planning to help the world out by producing 40% of the world’s lithium by 2030. A great lot of good Bolivia will be. Its spent nearly US$1B in the past +10 years to so far produce 500 tonnes of LiCO3 per annum and some fertiliser. And then there is the forgotten metal – TIN. Although it is used in very tiny amounts in everything electric, including electric vehicles, its usage in electric vehicles is about twice that in a ICE vehicle. Mined tin production has been in deficit for years. If it weren’t for scrap recycling then there would have been a tin catastrophe years ago. And no, tin can’t be substituted. There are just a few potential new tin mines on the drawing boards. No where near enough to fulfil this stupid pipe dream. And I’m sure the same can be said for nickel and cobalt. Absolute bloody morons. Nothing can be planned or constructed without engineers, and all the idiot politicians and bureaucrats all over the world (including Australia but except China I suspect) have forgotten to ask the engineers if it is possible.
