The Gov is controlled by Banks, energy and mining industries so its always going to be biased research sponsored by big energy & its network. I logically will never support coal knowing and experiencing what my friends suffer living near these dirty industries. Nukes even worse.
There is plenty of independent research not related to politicians and energy companies and here is an article the other side that steers towards sustainability but the links show the research behind this other side of the argument. Mining, processing, refining then transporting liquid fuel is very inefficient for starters and liquid fuel industry is heavily subsidised. Maintanence of service stations, cars driving to fuel and many other factors including controlled world prices of fuel will keep evs at bay until the prices can no longer be sustained for liquid fuel as viable.
Energy companies invested heavily in liquid energy will keep their already invested interest and infrastructure as long as they are subsidised.
The mass production will increase efficiency of EVs but also the lack of servicing in comparison to an ICE car is superior even tyres wear less with regen braking.
