These are misconceptions, or rather a bit out of date.
Wind and solar are much cheaper than fossil fuels now. Significantly cheaper.
And is an old school investment bank presenting this information.
Even for running a car, using solar-produced electricity is a fraction of the cost of gasoline; gas is 3-5x more expensive.
And nuclear is not anywhere near as cheap as wind or solar unfortunately, although we haven’t put much effort into making it more efficient for a few decades now so that might change.
Haha the way you described here what happened makes it clear that you had to keep rewording it over and over to get them to understand
