German TV (@WDR) and car industry (@AudiOfficial) lying about electric vehicles. Again. See picture.

An official looking TV clip is making its ways to Audi car salesmen with points against electric vehicles that are simply wrong. Let me explain in a short thread.
WDR is based on a Fraunhofer ISE that I debunked in 2019: very sloppy attempt - paid by hydrogen lobby - to make electric vehicles look bad.

In the thread I explain in great detail all the many things wrong with this study. It's not debatable.
There's even a German blogpost about it:…
This graph from the thread summarizes my criticism.
Authors defense tells us that H2 only wins IF:
- We exclude newest industry data AND
- We exclude batteries not made in Asia AND
- We assume batteries are dumped while in perfect shape AND
- We assume H2 electricity emits 4x less CO2

Yes, it was that bad
I might have been the one pointing this out most forcefully and precisely but I was far from the only one and there are many studies since then. That this is still used means either a journalist that wants to distort or one that doesn't have a clue. Either way it's unacceptable.
As for @HaraldLesch: he seems to embody the classic example of the physics professor who thinks he knows everything better. E.g. in this anti-EV video the grid is overloaded by one million people charging at the same time on 350kW super fast chargers. Haha
In reality 90% of charging doesn't happen with a fast charger and you only charge once every few days and not at the same time. It's all such utter bollox. But he is very popular so the video was watched 3 million times!
In the WDR clip he says we much research the negative impact of lithium batteries better. But has he ever read this 300 page study of the EU by Ricardo that goes in great depth regarding that?…

Probably not: it would just upset his priors.
All in all: that we still find this kind of misinformation doing the rounds points to many people who really don't want to hear the combustion engine is history. I think fuel cells for cars are mostly a way to muddy the waters.

Anyway: please don't believe this clip.
I must apologize. Somewhat

I know my calculations are correct but the ones I criticize are from a brand new Fraunhofer ISI study. It has a layered structure with studies based on studies based on studies

Will determine its exact assumptions this weekend

America was very lucky that its generals take the constitution more seriously than its president, one of its political parties and most of the voters.

But a democracy that needs to be protected from its elected officials by generals is a dead man walking.
I studied political science and it seems to me US democracy has become a reality soap with imagined grievances and tribalism more important for most people than democratic norms. And utterly irresponsible politicians will be able to run again with not even a slap on the wrist.
For me the root cause is irresponsible voters who think they can behave like hooligans at a football game. Who think politics is entertainment and they can just vote with their gut. Who are so insecure, coddled and entitled that they think they can choose their own facts.

Time for some Law and Order? Image
Can people inside the US explain to me why people like this are not arrested?
And is it me or does police seem to be awfully sympathetic?

If I where American I would want to know who in the police aided and abetted these idiots.

The @guardian has a new piece on the well known problems related to electric vehicles, solar and wind.

I think the focus on resource use and responsible mining is great. As long as we also remind ourselves that fossil fuels are worse.…
Remember that a car burns ~ 25 000 liters of fossil fuel over its lifetime. Do you really think that's better than 200 kg battery materials that's recyclable? And cobalt is also used for cleaning fossil fuel.
Apart from climate change the amount of ecosystem degradation, direct human suffering, conflict and corruption due to oil is much larger but that apparently generates less clicks.…

New open access publication in Nature concludes: meat should be more than twice as expensive if we take climate damage into account.

short thread…
ht @JMoVS
First I should be more precise:
- This is for the German situation.
- It looks at the price for farmers.
- There are large differences between types of meat and whether they are produced conventionally or organically.
This table shows the emissions per foodstuff in kg CO2eq per kg of foodstuff:
Beef 37 kg
Poultry 16-20 kg
Pork 6-10 kg
Eggs 1-2 kg
Milk 1 kg
Cereal 0.2-0.4 kg
Fruit 0.2-0.3 kg
Root crops 0.1 kg
Vegetables 0.0 kg

Der @BILD (large German magazin) claims that electric vehicles emit MORE particulate emission according to a new @OECD report.

This is a lie, plain and simple, if you actually read the report. Which I did because I research this at the @TUeindhoven.

I made a graph to show it.
This thread that I made a while ago contains all the details.
The report is very friendly about gasoline and diesel bc it conforms to official tests that we know are too optimistic about exhaust (e.g. from #dieselgate) but even then it just claims the problem won't go away when using EVs although there's a small but significant improvement.

Some people want us to believe there's not enough solar energy available to cover our worldwide energy needs

They often use EROI (Energy Return On Investment) as their metric

This is a rant against these EROI people misinforming the debate, based on a rebuttal of a 2020 paper
In essence the approach of the paper is straightforward:

1) Discard water and 96% of land because it's supposedly unavailable

2) Assume solar cells on just 1/5th of the remaining 4%

3) Complain that production of solar panels takes a lot of energy…
About 1) (available land)

Discarding 96% of land seems pretty extreme:
30% of the world's land is barren
40% of the world's land is used for meat

I think we could find more than 4% if we tried
(but we don't have to: we need less than 1%)
