Yeah.
I really don’t want to see text like this.
It would make things a lot more annoying to read.
I much prefer combining sentences by default. It’s natural to put a blank line between paragraphs, and Markdown was designed to make the natural thing render decently. You can put things on separate lines if you want, and it’ll always read nicely.
But definitely break things up into paragraphs if it makes sense.
Eh, I don’t think the energy use difference is all that important. It gets a lot more complicated if you factor in the ink drying out before being fully used, which means we’d need to produce and transport more ink. Also, a lot of the energy use for a laser printer is during warm-up, so if you print in big batches, the energy difference is a bit lower since it’s amortized over the amount of pages you print.
So just looking at wall power draw only tells part of the picture, and if you’re only using it a few times per year, it’s largely irrelevant (maybe a couple KWh/year difference?).
