11. Plus heat flow, and chemical energy, from thermal vents powered by the Earth's internal heat

(and radioactivity, which I believe is credited with keeping the centre of the Earth hot a lot longer than it otherwise would have remained), which may be a better candidate than radiation, since the capture of electromagnetic energy is a relatively advanced feature of life.

I'm not sure I believe Life has less entropy than non-life	Loki Liesmith	Jan 2019	#1
Entropy is the question how many ways there are to create a certain situation.	DetlefK	Jan 2019	#3
Respectfully I think that's exactly backwards	Loki Liesmith	Jan 2019	#5

Yes... ice has less entropy than water or vapor.	DetlefK	Jan 2019	#8

Correct, I should have said heat and radiation on a planetary surface/ocean is the best candidate.	eppur_se_muova	Jan 2019	#12
