That depends entirely on how cheap the alternatives are. Fossil fuel mining is not zero cost in itself, so there is a minimum price it can’t go below.

Indeed, quite a lot of coal plants are being shut down — they can’t compete as the fuel itself is too expensive. This is not universal as not all coal is the same price and transport costs are also relevant, but it is happening.

10$ for Saudis, 25$ for shell, 50$ from the Artic sea.

Per what, barrel of oil?

If that’s what you’re quoting (I’ve not seen any recent attempts to calculate the costs of oil extraction), each barrel has ~1.7 MWh of energy. By way of comparison, PV solar records are around $0.02/kWh = $34/BOE.
