And what will you synthesize gasoline from (the source materials)?
What are "(net) carbon-free sources"? I'm reading lots of terms without much substance.
Maybe we could ask the fairies to magic up some "(net) carbon-free sources" for our carbon-based fuels.

Why would you need fairies when you can get it from solar panels and wind turbines? If you make fossil fuels or hydrogen fuel from wind and solar energy you are carbon neutral.
No not really. I mean yes, fossil fuels shouldnt be used everywhere, but thats not because of the CO2 problem. 0 net co2 fossil fuels generated from solar is not making the co2 problem any worse. The problem is, its just not as efficient as using the electricity directly when possible... which is why any actual future will have both in it, electricity used directly when its the best choice, and 0 co2 fossil fuels when that is the correct choice... as with most things in life absolutism is never the answer.

You can use electricity, generated via renewable energy sources, to separate the hydrogen from water.
You could also use renewable energy sources to generate electricity so as to melt steel (e.g., to construct solar panels, wind turbines, etc).
The idea of making "fossil" fuels (carbon-based fuels or biofuels) is simply making more of the problem.
"net zero" is basically BS! (a way for industries to avoid responsibility for their CO2 emissions) It's not considering that human activities have already emitted vast amounts of CO2 into the atmosphere. Therefore, to even begin to start to reduce legacy greenhouse gas emissions, human activities will need to emit zero greenhouse gases and restore the natural carbon sequestration systems such as forests and peat lands.
