Urine capture would work great if it's attached to every person.

Even with renewable energy and electric transportation, if we could keep using oil but not produce CO2, then we should. Cheap energy is lifting humanity out of poverty.

You're assuming that the carbon capture process is cheaper than the shrinking price advantage of fossil fuels over renewables.

I'm not. I'm just leaving room for an equilibrium that includes oil.

I don't believe we'll be able to take cheap sources of power offline without affecting the bottom line for the developing world. Poor countries can't make the choice to regulate themselves into worse conditions.

Centralizing carbon capture at power plants can be cost effective. The tech is almost within reach. It will vastly increase the amount of available energy in the world.
