July was the hottest month in recorded history. I will say that again — we just experienced the hottest month EVER in the history of the planet. I do not want future generations to look back on this moment and ask why we did not do all we could to address climate change.

$2 a gallon gas tax with the money going towards a person’s down payment on an EV.

Brilliant! Oh, one question: how do we generate the electricity to power all those magic EVs? I'll wait. Also, before you suggest wind and solar, just know neither is sufficient.

The energy efficiency of an internal combustion engine is capped at 25% without accounting for getting gas to the car. Meanwhile, even coal plants average 35%, natural gas can get up to 60%, etc. Green energy provides around 40% of our energy now without producing CO2.

That's nice. I'll take your word for it. Of course, it's all academic given that the world's largest climate offenders (e.g., China and India) have no interest in curbing emissions. Until that happens meaningfully, the impact of EVs will be minimal at best.

To be clear, you can prove the car engine efficiency without to much math. According to Carnot's Theorem, the max efficiency for a heat engine is 1 - C/H, where for an engine C ~ 300 K (normal temperature) and H ~ 400 K (standard engine temperature), which gets you 25%.

Not disputing the relative inefficiencies of ICE. That's not the crux of my argument.

What I'm saying is that even if we switch to EVs right now without changing our sources for electricity, we will see a massive drop in CO2 emissions and other forms of pollution because we'll need to burn less fuel. Of course, it alone won't save us, but it will help.

For example, if everyone that could work from home worked from home, we'd also see a decent drop in CO2 emissions since we'll spend less time in traffic and less time driving in general.
