EVs have a toxic supply chain to make the batteries. EVs are position car companies in a climate conscious world. Instead, we should work on public transportation
Same with wind turbines. The amount of oil needed to create and lube them for their 20 year lifespan is absurdly terrible for the environment. The only actual answer is nuclear.
Recently in Australia supporting nuclear was considered right wing because leading up to election our most conservative party wanted to do it, while our less conservative party was talking about investing in solar/wind/etc. it became an either/or conversation by default.
I don’t see how we can make progress when even just talking about energy is such a politically charged topic.
I’d have to consult turbine manufacturers to see if entire gearboxes can be filled with it and still achieve the same performance, but there is contemporary evidence of using plant-based fluid alternatives to mineral oil.
Making the jump for turbines seems like a matter of political and/or corporate will
You should also note that most of the particulate emissions from cars are from tires shedding microplastics, and because EVs are heavier, their tires wear down faster.
Particulate emissions suck (especially like 6PPD for fish) but they are ultimately local pollutants, not global the way CO2 is. There are multiple variables to optimize for, and right now, EVs are better than gas vehicles.
The BETTER solution is obviously to get people out of personal vehicles as much as possible, and probably not enough, but there are bigger fish to fry. We have to do the most consequential things with the least cost, ASAP.
I did not note that because last I heard the EU was working on legislation to quantify tires and brake dust and I hadn’t heard anything about it since. I’m not sure if they decided that it was indeed something they’ve decided to regulate or not. I’ve since moved away from monitoring EU regulations and have been more focused on EPA/CARB.
At the very least I don’t know of any such quantifiable study and I’m hesitant to speak about things I don’t feel qualified to speak about.
FWIW, I’m not sure if tire wear counts as particulate emissions. Most of what I know of being measured is diluted exhaust, soot, particulate count in exhaust, and particulate mass in exhaust.
Quantifying tire wear microplastics seems rather hard to do in a laboratory setting. Your almost have to some sort of casing around the chassis dynamometer. Would that interfere with actually using the dynamometer? I don’t know. Maybe if you had a MFC to vacuum up the particulates. Alternatively, you can try to quantify tire wear separate from chassis testing but that would be outside the realm of what I am capable to speak about

You can use soybean-based or canola-based oil for that.
Cargill, Shell, and GE Prolec make it for transformers.
