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).
