It's a diversion tactic. The vast majority of greenhouse emissions come from large companies.
They want us to argue about irrelevancies amongst ourselves to distract from that fact.
Are EVs a net positive for the environment? Maybe. But that's like asking an atomic bomb survivor what they were wearing that day.
it's actually a pretty simple to figure out carbon footprint for gas powered cars. Gasoline is just a bunch of carbon atoms loosely linked together. You add heat, you add oxygen, and the carbon molecule bonds break in favor of bonding with oxygen to form carbon dioxide/monoxide, and release energy in the process. That's how combustion works. None of the carbon is destroyed in the process, all of the gasoline just gets converted into a gas; a greenhouse gas. Its why cars are the largest source of emissions in the US.
All of that is cut in an EV. With renewable energy sources there doesnt have to be any greenhouse emissions with EV's.
Gasoline is only part of the picture, however. For one, the chemical reaction by which concrete cures releases CO~2~, and concrete is responsible for 4-8% of emissions globally. Unless we're going to drive those new-fangled EVs on old-fashioned dirt roads, they account for significant greenhouse gases.
I’m no expert, but I’ve asked the same question myself.
First off, I’ve been told that yes, exhaust from I.C.E. vehicles is very much a HUGE environmental concern. That being said, however- due to issues with current electrical generation, means that unless large steps are taken toward sustainable green energy, running the current grid for enough to cover charging needs produces a comparatively close amount of pollution per mile driven. On top of that, is the issue with the rare-earth minerals needed to manufacture the batteries used in current EVs, which are extremely damaging to mine, especially in increasing quantities. And finally- once they are worn out, there is no reliably safe way to dispose of those batteries. And the current lifecycle of them averages around 3-5 years, so as more are disposed of, that impact on soil and water tables is projected to skyrocket.
So it’s a many-fold issue, and at the end of the day they aren’t necessarily WORSE than ICE vehicles, but they are also not really any better.
As for why people THINK they are super environmentally friendly? In a word- marketing.
A lot of ICE cars nowadays are hybrids which have just as many rare earth mineral requirements and still have terrible exhaust issues. EVs are a massive step up in sustainability.
