There are plenty of low-hanging fruit to pick before we get to reducing showering, one instance being home insulation. Meanwhile in places with district heating water is commonly heated via combined heat and power plants, making the carbon point somewhat moot. Of course in a fully-renewable scenario there would be no steam plant to provide heat, but here's where nuclear enters the picture. As for water: food has orders of magnitude higher water requirements. Granted, it's not the same standard, but at the same time you can't just pour whatever on your crops. Some treatment is always required. https://www.eniscuola.net/en/mediateca/water-footprint-of-food/ https://www.eniscuola.net/en/mediateca/water-footprint-of-fo...
