Some reports indicate that the costs of running an electric car are actually lower than the costs of running a car with an internal combustion engine.
But the actual cost of making one is going to create another shortage. Its battery will be the next problem that shall be made when most cars are already EVs.
I don't know if you heard this, but there is a new trend of mining right now under the ocean, where they will get tons of minerals and also use them for creating batteries. A lot of companies are racing on this to first make their own machines to extract those minerals, and it is also supported by governments as it is way less destructive than the actual mining we have right now, which destroys forests. Their main purpose also on this is getting ready for the demand for making EV vehicles in the future.
