1/ Thoughts on Disney's Analyst Day.

Obviously a longtime Disney D2C bull; I was astounded, shocked by slate's quality, range, volume.

This is Disney going beyond a digital "Vault" plus originals. It is saying all of your favorite stories, more,


2/ Not just a stronger Disney+, but one that hugely raises the tablestakes of competition, growth, press coverage, notability.

Paramount+ plans new Star Trek year round. Feels quaint now. Peacock will have a Jurassic Park + Fast series eventually.


3/ In "Content, Cars, and Comparisons in the 'Streaming Wars'", I wrote about how Disney $1B in content spend gets several billion of equivalent spend through its resonance

Mando was a top 5 show per @ParrotAnalytics in 2019. Disney thinks it can have 10 "Top 5s" a year.


4/ Trade talk can be misleading, but it takes only a cursory look at Twitter, the most popular shows of the past decade (Walking Dead, Thrones, Mando, Stranger Things), Disney's dominance at the box office (8 of top 10 in 2019) and wonder how to beat


5/ Roadmap doesn't just suck oxygen out of streaming wars (as Netflix did from 2014-18), it will enable Disney+ to rapidly grow its price

If I pay $54 a year to use Disney+ for 2 months, what happens when it's year-round?

Worth $15 month in
As bloody as the world wars were, they weren’t particularly bad by historical standards. The 17th century was uniquely bad for 2nd millennium AD, with Little Ice Age & glut of specie leading to state collapses & population decline across Eurasia.

Falls of Rome & Tang in 1st millennium were worse, but at least they were recorded. Records of the even worse Bronze Age Collapse around 1200 BC barely survived for some areas, & for other regions all we have are archaeological indications that they regressed to the stone age.


Further back in the 3rd millennium BC, an even worse series of catastrophes occurred - the Indo-European invasions - ending the Megalith Builder Civilization with their urban settlements & leaving much of Europe depopulated for 600 years.


By the time of their destruction the Megalith Builders themselves had been in a centuries long decline from their Golden Age in late 5th & early 4th millennium. Their great realms had likely disintegrated around 3500 BC into smaller chiefdoms engaging in endemic warfare.


The Megalith Builders themselves were the result of WHG chieftains overthrowing the decadent EEF chiefs like those of the Linear Ceramics around 4400 BC & subjugating an 1800 year old neolithic civilization. Possibly related to spread of copper-working.
China's Ultra-High Voltage Lines - Thread

1/14

China is building the world's most advanced UHV grid right now.

UHV lines are good for carrying power over long distances. The high voltage level reduces line loss. But they are very expensive to build.

China's UHVDC Network now:


2/14
In the rest of the world, UHV lines have generally been used sparingly. Submarine power cables (e.g. connecting UK to mainland Europe) and some huge hydropower projects in Quebec are some notable exceptions.

China is building UHV lines on a scale never seen before.

3/14
So why is China different? Geography plays a huge role. China's load centers are in the coastal East and South, while the best wind, solar, and hydro resources are in the North, Northwest, and Southwest. Power (esp. RE) is being generated far from where it's needed most.

4/14

In the past, poor regional interconnectivity has been a big contributor to low offtake levels of renewable energy. Of course a glut of coal power also played a role. Curtailment has improved in recent yrs tho. I discussed regional grids before:


5/14
UHV lines provide a inter-region backbone to transport power hundreds or thousands of km across the country. The UHVDC lines are used for the longest distances, while UHVAC lines are used for shorter distances, often within the same regional grid.

China's UHVAC lines now:
The anatomy of a scenario...

A 𝘁𝗵𝗿𝗲𝗮𝗱 on how mitigation works, why we probably need some level of carbon capture & storage (CCS) & carbon dioxide removal (CDR) - just not as much as in scenarios.

Based on my presentation ↦ https://t.co/j5uLxUi0xF


2. We start with a baseline or reference scenario, that assumes no or limited mitigation. If we want to stay "well below 2°C" we need to get rid of the dark grey & be net-zero!

We can argue about the baseline, but for the purposes here, it doesn't matter
https://t.co/C0dAdj65tl


3. The heavy lifting is done by conventional mitigation: behavioural change, energy efficiency, fuel switching (fossils to non-fossils), changed transport, dematerialisation, etc, etc...

But, scenarios suggest this is not enough to get rid of all greenhouse gases.


4. In some sectors, particularly some industrial sectors, perhaps the cheapest or only way to mitigate is with carbon capture & storage (CCS), eg, cement, steel, chemicals, etc

This is one reason we need CCS...


5. We can't forget about non-CO₂ emissions. We can probably get most non-CO₂ out of industry, but what about agriculture? Even if we change diet, reduce food waste, etc, we may not be able to eliminate CH₄ or N₂O from agriculture.

Some CO₂ & non-CO₂ remains (dark grey)...
