There are some truly ill-informed sheep in this chat.
1) the emissions caused from mining the rare metals for one Telsa are greater than the emissions created in the production and lifetime usaged (including oil drilling, refining, and transportation) of the average post 2009 petrol vehicle. This is not even considering the emissions created from producing or recharging a Tesla throughout its lifetime. Nor the emissions created to safely dispose of the HIGHLY toxic batteries.
This is just the emissions just from mining a small portion of the materials. This is due to 2 reasons:
a)95% come from China or other third world countries which don't regulate the mining emissions or have to abide by international eco treaties.
b) metals are extremely rare and or hard to mine due to their natural deep and thin layering in the earth's surface.
2) Removing an EGR valve over the average 15 year lifespan of a petrol vehicle, equates to 3% of the total emission created by the reduced MPG.
So appreciate all your eco warriors who think you're support a just cause, but your on the wrong side of the battle for the time being....you're on corporate government side and regurgitating lies.
I'm happy to share all studies which support this. I'm an electrical engineer so it's obviously not in my interest but can't stand the false sense of eco heroism these lies are creating.
Don't be sheep and just repeat what you heard on BBC or CNN, be better than that and educate yourselves.
