When you’re setting energy policy (or any policy really), you’re setting it for “normal” conditions. Which is to say, you can only design for what you know and what you can predict. While all of these things could happen, we only have a narrow view of what the future looks like. So we plan for what we know and we try to address what we can. If we see volcanos darken the sky or sustained, dangerous winds, then we’re dealing with different conditions and different policies apply.
