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.
Solar and other means of generating electricity may replace crude oil and gas but this will take a long time. It may not even happen in our generations. With what I see that is happening now, crude oil and gas can not yet be replaced, it will take a long time before it can happen.
I don't think that it will take a long time before oil and gas products will take time before they will be phased out by solar because there are allot of call both from the local and international schemes of every country electric cars and things are taking over and that is happening very soon and it's not too far again.
Climate change exparts and other world organizations has to set a time period for everyone country of the world implement laws that will be favorably to making sure that the environment is protected
