You can deploy solar and batteries rapidly, Australia is doing it.

Australia has the highest number of solar panels per capita in the world. Batteries are following suit with government subsidies. Yet, Australia has some of the highest energy prices in the world, its not a fool proof solution.

My comment wasn't even really about coal, it was about oil (and fuel). I'm talking about transport (even public transport) but planes & massive tankers are the big consumers. The original point is simply we cannot just stop ships.

When ships stopped due to the routes being blocked, we pushed ever closer to a recession and people starved and died because they were denied critical produces, equipment, food and medicines all over the world. Not to mention cost of living. This is what I mean by we "cannot afford" to not use oil.

We cannot afford for the routes to be shut, we cannot ban boats, cars, planes without major economic downturn.
