Not everyone agrees that the numbers don’t work for power generation. As for gasoline cars, I already posted the link in an earlier post showing that auto manufacturers have already decided to go all electric.
“Today, nearly 18% of all electricity produced in the United States comes from renewable energy sources, such as hydropower and wind—a figure that is forecast to climb.”
“NREL’s
Renewable Electricity Futures Study estimated that 120 gigawatts of storage would be needed across the continental United States by 2050, when the scenario imagined a future where 80% of electricity will come from renewable resources. The country currently has 22 gigawatts of storage from pumped hydropower, and another gigawatt in batteries.”

Three quarters of new power generation being added is currently solar or wind so the trend is going to have to change if they are not going to become dominant. There are technical challenges particularly in storage but many believe they will be solved.
Of course, another “wildcard“ that could change everything would be development of practical fusion power.
