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.
The only thing I see will replace crude oil is electric powered machines. For example people nowadays install solar system in their homes and this has gradually replaced generator and reduce the cost of living expecialy the expenses of prepaid meters. Now we have electric powered cars, electric powered motorcycle and the rest of them. All this innovation will help to shape the the industry in another dimension. Although crude oil and other natural gas may still work alongside with the new innovation and not going to be replaced. The only thing there is that it will make life more easier and reduce the cost of living and also reduce the level
oof air pollution in the environment.
