Thankfully water falls from the sky and our residential use of it barely amounts to a single digit percent compared to industrial and agricultural consumption of water. Unfortunately some regions charge residents way too much for it and have the gall to try to convince the populace that reducing personal use of water will have any meaningful impact. All so they can get back 0.1% of the total water used so they can spend a few more minutes watering lettuce they’re growing in the desert.

If you are concerned about water usage then animal ag is the big thing to remove from your life.

Generally just consuming less, huge amounts of water get used making completely unnecessary shit like softdrink.

In terms of energy usage generally the vast majority of a household’s energy usage is driving. So my advice?

Walk or cycle where you can, go vegan, buy less junk, and guiltlessly enjoy long hot showers outside of drought conditions.

If you like absurdly long showers look into mist showers (saves water not energy) or just water shaving shower heads.

Yes, but I do like to do these things sometimes and then pay a penance by not flushing for a week.
