Because greenwashing with batteries mined by children and vegan soy-based food from toxic crops are just a way for snobs for virtue signaling.
I don’t understand why this simple physical problem of absorbing more infrared radiation has become confused with class warfare. I don’t think the US manufactured batteries are more tied up in child,labor than like regular clothes and chocolate, and ending child labor across the globe is mostly independent of how we power transportation and energy.
There is a lot of greenwashing, but actually converting sectors of the economy to non-fossil fuel is not an example of that.
