It's a nice thought but coal was on the way out far before this calamity. Biggest hole in that theory is it takes money to install and use many forms of renewables. We may find that in short supply for awhile and business will use whatever cuts into profits least. And if nothing else this has demonstrated (at least in the USA) that greed is alive and well in corporate thinking. Witness hospitals laying off worker because profits are down due to elective surgeries being curtailed. Heinous behavior in my opinion. Profit is not supposed to be a motivator in the running of a hospital. Not to mention grocery stores have taken this as an opportunity to gouge a little more.

I'll stop before it becomes a full fledged rant.
