Two well known conservatives @PierrePoilievre and @MarkPMills convincing each other that EVs might be worse for the environment and the science is unclear.
As a scientist that actually studies this I can assure you that the science is clear and EVs much less CO2.
🧵
First objection: batteries are largely sourced from China because of Cobalt and rare earths.
Correct answer given in the video: North America used to produce 80% of this stuff but decided it didn't want it anymore.
Me: yes, it's basically like a lot of other stuff from China.
What drives me crazy is that Canada has SO much more resources than tar sands.
But somehow conservatives only want to produce fossil fuels and then start complaining that the alternatives (which are much cleaner) are not perfect.
Get off the couch and embrace the new economy!
Second objection: because China uses lots of coal "the honest scientific answer" is that we don't know if EVs emit less CO2.
I'm sorry, that's not "an honest scientific answer" but an objective untruth. EVs emit a LOT less CO2. This is what I've been researching for >10yrs now.
My pinned thread gives lots of example studies but you can also play around yourself and e.g. choose a battery from China and Denmark energy mix (=comparable to Canada). transportenvironment.org/what-we-do/ele…
So this is another example of "people are entitled to their own opinions but not their own facts".
EVs already emit less than half of the CO2 of comparable cars and have the potential to get very close to zero emissions as we green electricity and mining.
That's a fact.

Brilliant video pointing out 2 flaws in major energy models that make us invest too little in renewables and too much in fossil fuels: 1) Underestimating renewable price drops 2) Assuming fossil capacity factors stay the same
Many (e.g. I: hindawi.com/journals/compl…) have pointed out this is how you should model but Grubb et al prove that adding it to DICE means DICE will tell you to invest 2-5x more in clean stuff right away.
That means: stop investing in fossil fuels if you love your money!
I must admit the details of the math confused me at first. It seemed unnecessarily complicated so I asked my friend @nworbmot to take a look. (He's a quantum physics scientist who now makes energy models: he can do REALLY complicated math.)
First off: there is no protection in place for farmers now and the UK should really avoid competing head to head with the atrocious way they treat cattle in Australia.
BUT this is better fixed by standards.
I'm not a lawyer but rules should follow logic and logically it's simple: if practices are illegal in the UK then meat produced using similar practices in Australia (irrespective of if it's legal THERE) should be illegal in the UK.
A new blogpost claiming it takes nonsensically long for an EV to negate its battery production by overestimating battery production and underestimating battery lifetime.
This time by @go_rozen.
Today @exxonmobil is hit (and rightly so) for it's plans to expand emissions while @bp_plc and @Shell are moving beyond oil. But when I go to @Reuters world website, exactly half of all paid content is from Saudi @Aramco and it's the most blatant greenwashing I've ever seen.

"For some, the idea of an oil and gas company positively contributing to the climate challenge is a contradiction. We don't think so."
A new 'policy brief' for the Victorian Government in Australia has convinced them to create a road tax for EVs.
It wrongfully claims EVs emit more CO2.
If you follow me you know that's not true so I guess I have to do another debunk.
It's written by a group of architects and urban designers dreaming of a city with less cars who are apparently afraid that electric vehicles (EVs) will delay phasing out gas guzzlers.
