That said, I am also quite a bit more pessimist than OP that we will see a full conversion in the near future. It will be a long, and quite possibly painful, process.

Then, you have the issue of rolling out updates to grids. There's a variety of options, all well technically understood, and little movement in many areas. California, for example, ought to have buried a lot of its electrical lines. Construction work during droughts seem like a good way to start a wildfire, as is installing new overhead lines.

I'm just being pedantic though, I agree with your point.
