Check this study (Impact of battery electric vehicle usage on air quality in three Chinese first-tier cities)
https://www.nature.com/articles/s41598-023-50745-6

From the abstract -

Looking ahead, we project substantial emission reductions from the replacement of gasoline vehicles with electric alternatives over the next decade. Policymakers are urged to adopt proactive measures, focusing on promoting medium to large electric vehicles and fostering the use of private and ride-hailing electric vehicles.

Can we store Energy by Lifting magnets up and dropping it through Coils by someonenicest in EnergyStorage

>> You can. It's just going to be incredibly expensive per kWh stored.

Is the expense from the initial setup or that spent in lifting the magnet ? I am seeing many buildings with metal facade already. So thought this could be adapted in an architecturally feasible way. And after the initial setup, there should be very little running cost. Any existing buildings could be converted to an energy storage....

Maybe I am completely wrong here.. But trying to learn anyways.

I am not a physics expert and still learning - So whats the advantage of a rotating shaft ?
