If resilience is the concern, it's a lot easier to produce and store electricity locally than to produce gasoline. If Ukraine is an example of what happens when a grid is unde attack, let's put it in perspective: power goes out, then it comes back, then the russians strike again, power goes out, power comes back. Foreign aid brings in substation equipment to replace what's been blown up. It's not great but the energy itself isn't being destroyed, only distribution of it to a specific place. In many cases parts of the grid that aren't blown up pick up the extra distribution load in minutes. By contrast, when in the same war someone strikes a fuel depot, the depot, the fuel in the depot and the future capacity of that depot to store anything is destroyed pretty permanently. So now the affected party needs to truck more gas around to the end customers, burning some of the gas the customers were supposed to get. It's a much less resilient system.

California (or Texas last winter) sounds like poor management and perhaps corruption, but you don't judge the course material by the D students.
