Upwards - It would probably take more than $1 per person!
I'm assuming the number was originally a guess at the money that would have to be poured into research to achieve RE < C, because less than $100 per person for a total switch to renewables is clearly wrong. That's a bit too handwavey to be included amongst other hard figures on a graph like this though.
