What you should know is that change is permanent before it used to be coal before it shifted to oil and gas so definitely the world is going green in terms of clean energy which oil and gas doesn't guarantee countries like Saudi Arabia should look for other things to venture into because the fact remains that oil and gas is not sustainable even in military countries are talking about electric and magnetic powered fighters jets so it's a matter of time that the world will change from oil and gas
Truly it'll be difficult to electrify trucks and tanks, these are heavy duty machines, and aside for energy production, oil and gas serves more purpose in production, like for plastics, Asphalt for road, tires or even paints. All these are reliant on oil and gas which may not go away quickly, for the sake of green energy. Although the oil and gas industry is supposed to face decline, but the resources itself won't be a thing of the past anytime soon.
