It seems almost certain that oil and gas will one day become history, the world is clearly moving in that direction. Even now, electric vehicles, solar, and wind energy are already changing the game significantly. I think the real turning point will come with hydrogen and battery technologies, because storing energy will be the most critical issue of the future. So in the long run, it won’t be just one thing replacing oil, but rather a combination of these renewable sources and storage solutions.
Even in the distant future, oil and gas will have significant value, but not as energy sources, but as raw materials for various industries. Other chemical elements and their compounds will be made from these hydrocarbons, which will be used as food, in the chemical industry, in construction and other industries. Their use as a traditional source of energy will gradually be prohibited.
