The thing is people want cheap things. Take for example clothes, no one wants to pay $300 for a pair of pants if it can be had for $100. Interesting you mention the power grid which is a very important consideration, yet government is shoving EV cars down our throats and forcing car manufacturers to produce more EV vehicles and reduce the amount of IC vehicles being produced. And do not forget government's and corporations greed for rapidly increasing population will also further increase the demands on the power grid, that is no secret. The targets set by the government are unrealistic which is more proof that government intervening is making things worse. I agree with you that the transition must be slowed down, but what to do? Left-wing governments are forcing this on everyone.
These things should be left to the free market, they will find the best solution. Look at the horse drawn carriage, the IC engine replaced them all and no government forced rules were needed, the free market came up with a better product and it caught on. Believe it or not but during the early 20th century the electric trolley bus and even electric cars were out first. The first electric car was built during the 1840s and the first practical electric car was made in 1890 and the performance was impressive for the time. Electric trolley buses dominated the public transit landscape throughout much of the early 20th century till the late 50s. So what happened? The free market came up with a far better product, the IC engine more specifically the Ford Model T. It was much cheaper, had much longer range, did not rely on electric grids, and could be refueled within minutes. It was not really till WW2 that the IC engine really caught on and especially when the electric started motor was invented, it meant the doom of electric cars. The infrastructure used for refueling started from buying motor fuel, naptha, and benzene from hardware stores and pharmacies (which came from the byproduct of kerosene production) until government prohibited stores from selling gas at the pharmacies and hardware stores and the dedicated gas station was invented. In the 60s, IC buses rapidly replaced all electric trolley buses due to massive advantages. Montreal had electric trolley buses up to the late 50s and then all were removed. So the point of the history lesson? Is that government never forced IC engines, the free market came up with a better product and it caught on.
I believe that when free market comes up with an EV that is better and cheaper then the IC engine then only then will it really catch on and infrastructure will be built. Government should stay out of it. And your last sentence is golden, EVs are far from an eco friendly solution, it takes diesel to mine the materials to build the batteries and a lot of cheap foreign labor is used to mine the minerals.
