Alternatively, keep burning fossil fuels, but overproduce renewables on average, and use the waste energy for carbon capture.

(This has the big advantage of buying time to decarbonize things like concrete, cattle and airplanes.)

Wouldn't it be more efficient to not produce the carbon than to produce it on one side and capture it on the other?

[jeffbee]

Whether something is more efficient might not be relevant. What's relevant is whether there is a path from here to there that keeps us under a survivable amount of climate change. Staying on that path may require some decisions that seem superficially inefficient.
