> Modern bathing practices are a textbook example of an unsustainable lifestyle based on fossil fuels. Hot water production is the second largest energy use in many homes (after space heating and/or cooling), and much of it is used for bathing or showering. 2 The modern bathroom also uses a lot of water and adds extra energy use through space heating and waste-water treatment. Building and renovating bathrooms requires resources, too.

This is something that uses around 10% of our electricity production (it that) and 10% of our square footage. You'd cut that in half maybe.

If that's unsustainable then so are a massive number of other things so I'd like to see what the author thinks is a sustainable society. I'd guess if you cut all the ~5% waste sources you'd end up living in something akin to MegaCity One. And if all those 5% sources aren't unsustainable but this one is then why?

I get it, it's a click bait line which I fell for but that doesn't mean I have to like articles like this.

You expect me to deal with all the -5% waste sources in one article?

Please explain me: what is the minimum share of total energy use that any activity should have before someone is allowed to dedicate any attention to it?
