In the face of conspiracies and global problems, scientists need to become better storytellers.

Of course facts come first.
But conveying them in a way that is engaging, memorable and inspiring is important too!

I found that out the hard way and I have some advise.
Thirteen years ago I felt like I was just making money, not improving the world. I took a sabbatical in search of meaning.

I found that solar, wind and electricity storage where improving in predictable ways that promised cheap, clean and abundant energy forever. It inspired me.
I decided to dedicate my life to accelerating the transition to sustainable energy and mobility. To make a name for myself I wrote a book about electric vehicles.

After many months of long days researching and writing I proudly presented the result to a good friend and editor.
He said: "Interesting topic but you really make the reader work for it."

For those of you who don't write: it's about the worst thing you can possibly hear. I was devastated.
But he told me that I might be able to save the book by becoming aware that I was telling a story.

He also gave me a couple of books on story.
For me two stood out:

"Story" is a book for aspiring Hollywood script writers that made me aware of the importance of conflict.
"The Hero with a Thousand Faces" by Joseph Campbell places stories in a rich mythological tradition.

I learned to think in terms of story arcs and taking the reader on a journey.
After three more months I gave him the new draft and he asked me: "Who was your editor?"

And I said: "The books on storytelling you gave me."

He looked at me for a long moment and then said: "Well, it's high time you send this to the publisher."

I'm not claiming the book is a great story but the experience made me aware of the importance of stories.

You should be aware that you tell a story, and you should respect your audience enough to tell them a good one.
That also gets your message across much better.
Since then I always tell my students to focus on storytelling and to at least ask themselves:

Start with the problem you are addressing.
Why does it matter to you and me emotionally?

Then show how you are solving that problem.
How is the solution satisfying on a personal level?
Simple example: a student had modelled electric trucks. He had done good research on an interesting topic but his thesis presentation was boring.

I asked him the previous questions and he came up with this step towards a storyline:
"Chennai, the city that I come from is known for its beautiful beaches.
But if you live there, it's not the beaches but the air pollution from traffic that is most noticeable. It makes us sick and shortens the lives of the people I love.
Electric cars and trucks could drive out the demon of air pollution. My research shows that electric trucks are possible. Now I can dream about my city becoming healthy and clean."

This made all the difference to his presentation.
Onwards to climate change.

It's often told as a tragedy and that really resonates. But this makes the story depressing and paralysing while many people resist being cast in the role of loser.
presentation-guru.com/on-structure-t…

So I want to present some alternative storylines.
The most straightforward choice is to tell it like a quest. Climate change is a call to action. We embark on a mission towards clean abundant energy and stop climate change by reducing our emissions. It takes heroism and there will be suffering but we'll save civilization.
You could also make it a rags to riches story where climate change is just a temporary setback but the overall trend is that we lift everybody out of poverty after we overcome the problems caused by our unfortunate focus on fossil fuels.
Personally I like the rebirth story:

Fossil fuels and consumerism have us trapped in a vicious cycle.

But using science we discover clean technology and what really makes us happy.

This enables us to break the spell and after many adventures we finally live happily ever after.
Now my point is NOT that we should make stuff up!

I *hate* it when climate problems are exaggerated to apocalyptic proportions. That mostly leads to despair and paralysis in the short term and lack of credibility in the long term.

This is not a sprint but a marathon.
I also hate it when renewable solutions are oversimplified. We need more than some miracle technologies or simple behavioral hacks.

This is complex stuff and denying that gets us nowhere.
I just ask that you think about how you 'package' your information. How can you make your research a call to action with your reader in the role of hero(ine) saving the day?

Because us scientists having the facts is not enough.
The world also needs our storytelling capabilities.

But lo and behold: this 2017 study was updated by the authors themselves in 2019 and what did they conclude?

Emissions between 61 and 106 kg CO2eq/kWh.

It's hard to overstate how outdated it makes this 'new' study by VDI. And I'm disappointed that @handelsblatt didn't see this.
Of course battery emissions will continue to go down (also - not surprisingly - faster than VDI assumes) as production becomes optimised further and as renewable electricity is used in mining and factories.

Basically emissions of EVs can go down to zero.
sciencedirect.com/science/articl…
By now most people know 90% of biofuels are a bad idea and they are best reserved for hard problems like aviation.

But combustion engine proponents have one last trick up their sleeve: eFuels!

The idea is simple: go to other countries and produce fuel using green electricity.

German quality newspaper @handelsblatt reports on new anti-EV study by German society of engineers VDI (@VDI_News).

VDI states that electric vehicles emit more CO2 than combustion engine vehicles due to battery production.

But VDI uses wrong numbers for...
battery production. Image
For those who don't know me: I research energy systems & mobility at the @TUeindhoven and specialize in comparing CO2 emissions of electric vehicles and combustion vehicles.

My recent study about that in German:
dropbox.com/s/2gwq0yslascu…

and English:
dropbox.com/s/xblk4g7zeboa…
My main problem with the VDI study is that they use wrong numbers for battery production.

They assume producing a 48 kWh battery emits 8,9t of CO2.

That means 185 kg/kWh (8900kg/48kWh). Image

I think climate change should be our international top priority. So why do I help to discredit the recent article in the @guardian about the Arctic methane 'bomb'?

Because:

Truthful arguments last longest.

We should not panic or cower in fear but ACT: we have the solutions.
It's the same reason I attack:

Outdated scenarios like RCP8.5 (too often called baseline/reference)

Nonsense like 'Planet of the Humans'

Lies like EVs/solar/wind solve nothing

Untruth just muddies the waters and makes it harder to act.
IF we should give global warming the same priority as e.g. a World War we would soon have it under control.

Of course it is not a 'war' because we only reduce death/suffering and increase prosperity for all. Also the enemy is within so shooting him or her is not a solution.

What a sad story: German car manufacturers association @VDA_online commits to climate neutrality by 2050...
BUT...
sees important role for combustion engines & eFuels
(a hideously expensive & inefficient combo).

Only @VWGroup embraces the electric future.
cleanenergywire.org/news/german-ca…
If you are wondering why I scoff at eFuels for cars, just look at the chart. And know that all these efficiency reducing steps require expensive equipment too as @transenv shows in its famous efficiency charts.
transportenvironment.org/press/e-fuels-…
Also know that heavy trucks will be able to drive without weight penalty and at much lower energy and maintenance costs in a few years, due to the electric drivetrain being lighter (researchgate.net/publication/33…)...

This German article criticises the "foolish" and "irritatingly energetic" focus of @volkswagen on electric vehicles.

I think the fool that's being exposed is the writer and we need acceleration, not uninformed attempts at procrastination (short rant).
cicero.de/wirtschaft/zuk…
First question in the article: "Shouldn't we focus on synthetic fuels when most cars will have combustion engines in the forseeable future?"

The writer apparently doesn't know synthetic fuels require much more energy and are much more expensive.
"Extremely expensive charging infrastructure"

The writer really doesn't have a clue. I *make* these kinds of calculations and yes, it will cost billions, but compared to e.g. hydrogen and synthetic fuels he trots out here again it's pocket change.

Nieuw rapport: kosten stimulering elektrische auto's VEEL te hoog ingeschat door Algemene @Rekenkamer

Naarmate je realistischer en minder kortzichtig wordt zit de Rekenkamer 3x, 10x of 50x (!) te hoog.

Ik vat mijn oordeel even samen in een draadje.
rijksoverheid.nl/documenten/rap…
Ik maak deze berekening al jaren op een vergelijkbare manier en schreef laatst een vernietigend opiniestuk in @Energeia_Nieuws.

Hoop dat jullie nu eindelijk luisteren @Rekenkamer: effectief klimaatbeleid ontmoedigen met onzin-berekeningen is NIET OK!
energeia.nl/energeia-artik…
Ik weet dat "onrealistische assumpties" diplomatieker klinkt. Maar het zijn volgens mij gewoon grove fouten. Jaar op jaar. Gekmakend!

Wat me ook irriteert is dat @PieterOmtzigt die fouten overneemt. Want op andere gebieden is hij voor mij een held:
