Well, fuel are a limited resources so it's expected to get more expensive in the near future since there are less more of the resources needed to create the fuel.
I beg your pardon - wrong opinion. Let me explain: if this resource, in the future, would have a stable or growing consumption, I would categorically agree. But in the next 10-20 years, the consumption of these resources will noticeably decrease. The fact that market monopolists will resist this, and make "demonstration performances", as, for example, Russia did with gas on the European market, in response to Russia's failure to comply with its requirements.
