Yes. Skimming the first 10 minutes of intro out of a 4 hour video series isn't going to be very enlightening. Like reading the preface of a book and calling it done. I know 4 hours is a lot. That's why I always recommend for newcomers to start with the 1:20 Earth Day 2017 presentation. This is a fast, 20 second per bullet point, 200 slide lecture which highlights a lot of great concepts in a very short amount of time. 50 minutes on 1.5X speed. Keep in mind also that this lecture was just an off the cuff local Earth day presentation he threw together not even intending it to be any kind of Magnum Opus. Not a rehearsed and produced Tedx. And seeks to condense an 80 hour, 1,200 page class into 1 hour. Maybe it is just much easier for me to understand what he is getting at since I have taken the whole class?

I have watched these Nate Hagens videos you have provided and I think they are great.
I don't think its unreasonable to consider Nate Hagens a bit of an "energy genius" or at least expert.
The problem with the whole energy debate is that it's
joined at the hip with politics, so the truth doesn't have nearly as much power as it does compared to what political side you are on.
Also, we live in a world where the most easily absorbable and likable ideas win, at least in the short term over what might actually work.
This fits perfectly with wind/solar energy generation vs Nuclear.
Politicians like AOC have one clear skill above anything else, they combine tribalism with easily absorbable ideas, and then project these easily absorbable ideas even further for more power.
Probably the simplest and most recent example for AOC is the "New Green Deal" or just a video of her making a speech to a particular audience, where she instinctively talked in the same manner as the people she was communicating to.

To me, these types of politicians are what I like to call SJW/virtue signalling "super cancers" because, ultimately, in no way possible, are they helpful to the general public, because it's all just dumb. https://twitter.com/seanhannity/status/1121173231090708480
To me, Obama wasn't that hugely different on similarities, but AOC takes it to a whole new level.
Also, mainstream media news only likes to tell people what they like there to hear, their existence often depends on it, for example, look at the CNBC report where they merely just go over Tesla's numbers, but the video got more thumbs down than thumbs up.
https://www.youtube.com/watch?v=P_PBJKY9OFI
Or another example that came out yesterday, where mainstream media giant CBS posted a news headline Tweet about how a kid "plunged" from a 3rd story shopping mall balcony, when the ugly truth was a man had thrown the white kid over the balcony after being rejected from his advances to females in the mall.
https://pbs.twimg.com/media/D4mhj-kW4AUtt6b.jpg
Mark Dice then directly responded to the CBS to be more honest and said: "The white child was thrown off the balcony by a black man".
https://twitter.com/MarkDice/status/1119467802459430912
Most people are so sick of mainstream media trying to report things for maximum revenues and not being more honest that CBS got attacked on Twitter and actually fully deleted the news report, that's why you don't see the entire thread of Mark Dice's comment, because CBS deleted their own news tweet.
I came across this great article below the other day, what makes this article great is that its incredibly short and too the point.
Electric vehicles emit more CO2 than diesel ones, German study shows
http://www.brusselstimes.com/business/technology/15050/electric-vehicles-emit-more-co2-than-diesel-ones,-german-study-shows
When CO2 emissions linked to the production of batteries and the German energy mix - in which coal still plays an important role - are taken into consideration, electric vehicles emit 11% to 28% more than their diesel counterparts, according to the study, presented on Wednesday at the Ifo Institute in Munich.
Mining and processing the lithium, cobalt and manganese used for batteries consume a great deal of energy. A Tesla Model 3 battery, for example, represents between 11 and 15 tonnes of CO2. Given a lifetime of 10 years and an annual travel distance of 15,000 kilometres, this translates into 73 to 98 grams of CO2 per kilometre, scientists Christoph Buchal, Hans-Dieter Karl and Hans-Werner Sinn noted in their study.
The CO2 given off to produce the electricity that powers such vehicles also needs to be factored in, they say.
When all these factors are considered, each Tesla emits 156 to 180 grams of CO2 per kilometre, which is more than a comparable diesel vehicle produced by the German company Mercedes, for example.
^The other thing to note, is this data is not new, there are probably 1,000s of articles out there that report similar information over the years, I have posted a few of them over time, so I would be surprised if people acted like this is new to them.
What is great (as said before) is they made the article remarkably short which helps absorbability.
The fact is that so much more co2 emissions are created making a Tesla battery-pack that it's around equivalent of 10 years worth of regular combustion vehicle driving.
I have been realising that a lot of this stuff is really just giant-sized IQ tests, IQ tests are ultimately just sets of puzzles.
If a person has all the information in front of them and still don't understand it, then its either the person doesn't want to understand it (political tribalism) or the person is just dumb.
To me when I look at a Tesla battery pack, I am thinking about how much energy, and thus co2 was emitted making the battery pack merely just to "hold energy".
The energy it takes to mine and refine and process lithium/cobalt/manganese/Aluminum/nickel is a lot.
Even if you just take the nickel coating of 18650/21700 cells, the energy and co2 emissions for the refinement and processing of nickel is a lot, this is one of the reasons why nickel sells at over $12,000 per ton compared to other metals
https://markets.businessinsider.com/commodities/realtime-list
The cost of a refined metal comes from the major factors of "Demand", "Abundance" and "Cost of mining/refinement/processing".
https://en.wikipedia.org/wiki/Lateritic_nickel_ore_deposits
Lateritic nickel ore is now the most common source of nickel quote :"They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining of nickel."
The rich "easy pickings" nickel ores used to only take about 11 tons of co2 per ton of nickel, but these mines are disappearing if not gone, as nickel demand continues, so just like oil, the drillers need to go further out and deeper to get the commodity that at one time almost flowed out of the nearby ground with easy extraction.
Go down to , page 96, "4.9.5 Assessment of effects" / Table 15 "Total Tonne per Tonne Produced"
https://epa.tas.gov.au/documents/proto%20resources%20-%20barnes%20hill%20nickel%20laterite%20project%20dpemp.pdf
So most commonly mined and refined nickel comes at around
57.9 tonnes of co2 emitted per 1 tonne of nickel.

So merely the nickel on Tesla battery packs to coat and ensure no corrosion occurs on the cell indirectly causes a remarkable amount of co2 to be emitted. This is common with all metal refinement, they all create far more co2 emissions weight than the weight of the finished metal itself.
And this battery making process is all just to create a battery that "holds energy" in a similar manner as a comparatively very simple petroleum fuel tank.
The reason why Tesla uses this type of lithium battery cell is due to the fact its the safest known lithium cell ever devised in lithium cell history. But it still needs to be made safer.
Also, none of this even takes into account the co2 emissions to acquire and put the energy into the battery pack in the first place.
If you check out of the "tonnes of co2e per tonne of metal produced" PDF, you find copper is frequently 8tonnes of co2 per 1 tonne producted copper.
So copper averages about 4-10 times, all depends on the particular mine, some copper mines are about 20 times the co2, as rich ores get used up, lower yielding copper ores become standard.
Magnesium is about 35times co2 in its produced weight.
Bauxite/Aluminium is typically 10 tons co2 per ton produced
https://www.metalary.com/lithium-price/
https://www.metalary.com/cobalt-price/
https://www.businessinsider.com.au/cobalt-price-rally-2017-3
Lithium and Cobalt generally sit at very high costs per tonne, cobalt is typically now seen above $50,000 per ton, so logically the amount of energy extracting and refining these elements would of easily exceeded 10 tons of co2 per ton produced.
Gold is around an incredible 26,500kg CO2 per 1 "kg" produced, which helps explain why its so expensive, the energy to produce/refine the metal adds to the cost.
If you have a 1 tonne lithium battery it's easy to work out that there must of been at least 10 tonnes of co2 produced to make it, and that is probably being very much in the "giving it the benefit of the doubt" category, I would say from the co2 emissions to produce the core metals data for a lithium battery pack it would have to be at least 20 tonnes co2 in my opinion..
http://ecoscore.be/en/info/ecoscore/co2
https://www.transportenvironment.org/what-we-do/cars-and-co2
So for petroleum fuel it's around 120 g CO2/km
1 metric tonne of co2 is "0.00012 grams"
For the average car to make 100,000km of driving that is, 100,000km x 0.00012 = 12 tonnes of co2.
I drive an LPG car which is about 83 g of CO2/km
100,000km x 0.000082 = 8.2 tonnes of co2.
We have had people admit even on this forum that they get a new EV roughly every 3 years.
You can go to one of many scrap yard/insurance sites and see 100's of Tesla's that have been in an automobile accident with only a few thousand miles on the odometer, so these cars never got to displace an ICE vehicle's hoped equivalent emissions over time, they only contributed to it.
https://www.iaai.com/Search?Keyword=tesla
It's a known issue that Tesla's have been sent to the scrap yard for remarkably little visual damage because of inherent battery fire fears etc.

Insuance has gotten so expensive that a lot of insurers refuse to even offer insurance on Tesla cars, so now Tesla is offering its own insurance

About 1 year ago clueless Tesla fans on Facebook etc were metaphorically ripping my head off telling me that Tesla's were massively safer against fire risks vs ICE cars but every day now that we have more of them out there, this is being proven wrong.
But fires of parked Tesla's going off are being posted on social media at a remarkably frequent basis,

These cars, of course, won't be auctioned at insurance yards as they are well and truly destroyed.
The wreck is truly remarkable because of the extreme fire lithium batteries create
https://www.japantimes.co.jp/news/2018/05/17/business/swiss-prosecutors-investigate-fatal-tesla-crash-suspect-thermal-runaway-battery/#.XL1kXegzaCo
As time goes it fire fighting departments will develop training and information videos on just how difficult and dangerous lithium-EV battery fires are https://youtu.be/3eFM9JJMH_0
Just like solar, people let their bias take over reality with how long a product "should last", most "green energy" products have 3-5 year warranties, where they are EVs or solar panels. But the claim is constantly "it will last 25 years", everyone knows a comparatively simple combustion car rarely lasts 25 years before its deemed unworthwhile, the difference is combustion vehicles are remarkably simpler and easier to repair.
It's the same with Solar panels https://youtu.be/0L_lzUhitx8?t=193 , it shouldn't be a surprise to anyone that most solar panels are in fact deliberately made only to last a short multi-year warranty.
And I think it's the same with lithium battery products, I just don't see how it's going to last 25 years when you factor in real-world usage cycles. Sure you can find unusual examples, but most of this stuff ends up on the scrap yard in remarkably short timelines https://www.iaai.com/Search?Keyword=tesla

^Sure a EV battery pack isn't discharged this heavily, but the fact is the cells will lose substantial capacity over time, just like how we have seen with our own ebike battery packs. When using a high-power Supercharger on their Tesla for fast charging, they are in fact significantly shortening the total lifecycles of the Tesla battery pack, because we all have seen fast charging 18650 charts show equally damaging cycle life as heavy discharging tests. Such fast charging conveniences come at a price.
The other remarkable thing about Lithium cell technology is how little it has really changed over the last 15 years.
https://endless-sphere.com/forums/viewtopic.php?f=14&t=57256
^You can read through the first 5 pages of the "Thread for new battery breakthrough PR releases" and see incredibly convincing and sometimes very detailed descriptions/promises of how and why their new battery technology will be superior, but these posts are 12 years old now, and nothing has ultimately changed. I don't think lithium cell technology will ever change on a substantial level than what we see it doing now.
So electric cars at their current state, really are just a sadistic joke played on the general public, in terms of claiming to be lower in co2 emissions.
The only thing that prevents people from seeing a Tesla as more environmentally destructive than the traditional car, is the issue of EVs having invisible extra complexity and energy requirements in the manufacturing process that is not an easily absorbable fact.
Ideally and long term, people won't buy a lithium-based EV naively believing they are helping the planet, they will only buy one because they enjoy driving them.

It's similar to just weighing up wind/solar vs Nuclear where the wind/solar states are typically emitting 10 times as much co2 than a nuclear state like France.
Right now France is emitting only 27grams of co2 per KWh which is truly remarkable for the entire country of 67 million people.
https://www.electricitymap.org/?wind=false&solar=false&page=country&countryCode=FR&remote=true
^I am not going to snapshot it, u should have all seen it before.. Germany and SA are currently emitting almost 20 times more co2, if we were comparing car emissions it would be considered a complete joke.
--------------------------------------------------------------------------------------------------------------------------------------------
I came across this chart a little SLCOE while ago and I think it's great.
Because it shows a real-world example of LCOE chart by actually factoring in the "system on the grid".
Instead of just showing the cost of creating energy where the wind is blowing 24/7 or the sun is shining 24/7 which just isn't how the real-world works, it shows what it would take to have a system of 100% renewables taking into account the real-world variables and shows the total cost at over $400/MWh, which I really think it roughly it should be, much more expensive.
