It's a huge adjustment from how the past few decades have established expectations, and it'll take a big force to change quickly, similar to covid even though that was short term in hindsight.
That doesn't make sense. Batteries are an energy container, they're not energy itself. How can it be compared to a fuel? The direct counterpart to oil or coal is wind or solar radiation itself, batteries are used to amortize the supply and store an excess for emergency use, but otherwise those types of energy just immediately go into powering the grid.
The economic case for renewable power is actually extremely good, because unlike fossil fuels, they're effectively infinite and don't need complex infrastructure to extract. They're free. You only need a power plant that directly converts them into power. If we were just able to shift fossil fuel demand towards producing goods like plastics, this would already be massive. However, a lot of powerful people are deeply invested into fossil fuels and will do anything to tip the scales into their favor, despite gradually losing in the energy sector.
"It depends" is the correct answer, but the equation is shifting quickly towards solar + electricity.
Solar + electricity are not directly suitable for powering electric vehicles, that's where the batteries come in.
Comparing apples (transport of electricity via wires) with oranges (transport of energy via liquid or gas) misses the elephant in the room: you are not going to be able to use those electrons without a suitable temporary storage medium unless you plan on carrying a very long and impractical extension cord behind your now very light EV.
