Some day gas and crude oil will be a thing of the past. With innovations here and there. In your own opinion what will replace gas and crude oil in the international market.
Gas and crude oil will likely remain in use for the foreseeable future, but with the advancement of human civilization, innovations and the development of renewable energy sources will inevitably lead to a significant reduction in their consumption. However, even with this reduction, their use will not be completely eliminated, as there will still be specific needs for gas and oil, such as in remote locations, certain vehicles, and other specialized applications. This is why gas and crude oil will likely shift to becoming secondary options in the global fuel supply, much like coal and other non-renewable resources.
