The World's Transition to Renewable Energies

[Leonardo17]

Hey, I have a solution in which people can still keep their cars and planes and get off oil: synthetic ethanol. Now, I am not talking about that grown methanol but let's say people make solar thermal powerplants in Sahara where they use electricity to suck carbon from the air and take hydrogen from the water. Then they mix hydrogen and carbon and thus make ethanol that can run existing gasoline cars (with a little tweak), trucks and airplanes.

Otherwise, people should immediately stop flying, cut down on eating meat (like once a week), buy less, and stop using ocean freighters until they find a substitute for oil.

Sahara?  Water?

Yes that’s how they do it in Morocco to produce electricity. If you want green hydrogen it’s only a matter of logistics to bring some pure water to separate into liquid hydrogen and Oxygen.

Air is 78% nitrogen and 21% oxygen. I don't see us being able to extract a lot of carbon from it

There are already constructions made exclusively to remove CO2 from the atmosphere.

These technologies are very small scale. Carbon capture works in other places like cement factories and/or coal plants that have not been closed yet. We need hundreds of thousands of such carbon capture plants to obtain any significant change.

 
One thing we can do is capture carbon from sea water. Or use some chemicals that will cause the carbon in the ocean to sink to the bottom of the sea thus allowing oceans to capture more carbon without more sea acidification.
 
One think I have heard is that there not just one solution to climate change. It’s a combination of many different solution. I we implement them (although it’s not the most comfortable thing to do), we survive.
