I think you're missing that there are better ways to produce fuels for cars than to chemically synthesize petroleum. It's all about cost and efficiency if you're just looking for portable energy. Or we could burn more coal so we can generate the energy needed for synthetic gasoline....
The problem is, people can, do, and will use that exact same argument to say we don't need any more solar panels or wind turbines, because we don't need and can't use or store the excess power for anything and that's why we need to keep thermal plants as backup for base load generation. Look, when we produce too much electricity, the electricity cost goes to zero and negative! It's "wasteful and inefficient"! But these two problems can solve each other. Synthetic fuels (doesn't have to be gasoline, hydrogen is step 1, methane/LNG is a bit more manageable as a chemical fuel. As long as the carbon source is atmospheric, then it and other synthetic hydrocarbons are carbon neutral to burn) provide an on-demand energy sink/storage method that can support and drive more electrification and renewable power, it just has to be part of a consistent and systemic approach with strict regulation and a clear view of the big picture (something sorely lacking these days).
Nailed it.
We need a solar grid that can meet our demand during a 9-hour, overcast, low-angle winter day. That same grid will be producing more than 4 times as much power as we need during a 15-hour, high-angle summer day, even after we include air conditioning loads.
We need massive, seasonal loads to soak up that excess power and keep solar profitable.
Fake butter isn't going to do it, but things like desalination, hydrogen electrolysis, and Fischer-Tropsch hydrocarbon production are all likely candidates.
I'm glad someone understands.
