Exactly. One of the entire core values of having electrical infrastructure and equipment is to make energy sources perfectly fungible, abstracting generation details from usage. That in turn means that energy generation is always about economics and national strategy (which in turn often just boils back down to economics), the expense of any given method is the whole point. This often comes up with "peak resource" issues, which aren't generally about using up all of a given resource so much as using all that can be reached for a given price. What we're really seeing are fossil fuel industries finally starting to have to actually compete under a real Free Market as society becomes less tolerant of letting them ignore their massive externalities. If coal is more expensive taking into account not being able to dump expensive pollution into the wider world, then it can and should go away. In fact that cost should have always been taken into account.
