- What is a matter of security, because the state's energy security is a crucial thing, is a matter of a properly constructed mix, in which mix there must be various elements when it comes to energy sources: RES, but also traditional ones - coal, but also gas blocks, which are being built on a massive scale all over the world at the moment - said Wojciech Balczun in "Gość Wydarzeń" Polsat News.

- I am the last person to say that coal should not be in Poland's mix - he pointed out.

- Polish mines should undergo or should complete the restructuring process. We have certain concepts in this regard, but it is too early to show which direction it will go - he added.
