Energy needs to be affordable and this is the first pillar of energy supply when the energy transition is concerned, the minister said.  

Oman's official also defended, again, the OPEC+ decision to reduce the headline target oil production by 2 million barrels per day (bpd) as of this month, saying that the group is proactive in trying to balance the market.

Al-Aufi also said that he wasn't surprised by the U.S. blowback after the OPEC+ decision was announced.

"It was expected," he told CNBC.

Referring to the energy transition and renewables, Oman, like many Middle Eastern oil and gas producers, believes that all forms of energy will be needed to meet the world's growing energy demand in the coming years and decades.

Back in September, Saudi Aramco's chief executive Amin Nasser said that years of underinvestment, a lack of a backup plan, and alternatives not ready to step up and replace conventional energy are the real causes of this state of energy insecurity today.
