You are one of the few persons, I have found, who has posted about the power losses in the Electric Vehicle system. You have described an energy loss of about 16% from the wall power to the battery during charging. It is a power loss to consider when that electricity is being generated by fossil fuels.
There is one other power loss in this system that is forgotten: the electric transmission losses from the generation source. Since the Green Weenies want solar and wind, such sources will be located in areas far from their destination. Large land masses and the noise of wind generation are most likely found in remote areas. The distances traveled by the transmission lines will have power losses, also added to the use power losses:
Different power is lost at different stages:
1-2% of energy is lost during the step-up transformer from when the electricity is generated to when it is transmitted.
2-4% of energy is lost in the transmission lines
1-2% of energy is lost during the step-down of the transform from the transmission line to distribution.
4-6% of energy is lost during the distribution
The average loss of power between the power plant and consumers ranges between 8-15%. Things add up.
I thought of that for wind power. I hadn't thought of that for solar. Here in the south solar is fairly easy to decentralize and scatter it across many sources. Even if it's one solar farm per neighborhood, the solar farm feeding your neighborhood is liable to be closer to your house than the nearest coal plant, natural gas plant, nuclear plant, or hydro plant. Then there's my favorite version of decentralized solar: if you want it you buy it and put it onto your house (or land) for your use.
That's why my solar system works so well for me. I was incentivized to make it work efficiently for my needs because it cost my money and is intended for my benefit. That's exactly why I don't want "green" energy from the utility, forced onto us by the Dims. When they do that they have no incentive to make it work efficiently and cheaply.
Even though fossil fuels are so much more dependable and cheaper than solar power, the fact of the matter is that I can't produce my own fossil fuel or generate my own power from fossil fuels. Thus, the more I use fossil fuels the more the Dims have a hook to control me. However, the more energy independent I am, the less money they can suck out of my monthly budget to force me to pay a tithe to their greta cult of cow farts and hating the good climate life of the Modern Warm Period.
