I assume most of the water needed to sustain cows is spent on the plants they eat.
- dbcurtis 8y agoThis may well be. But at least in the case of the diary farmers that surrounded my home town, all the water used to grow the cattle feed fell from the sky.
- hycaria 8y agoIrrigation systems can be buried, so sometimes watering is not as obvious as it may seem.
- kragen 8y agoIrrigation systems don't use potable tap water; they use rainwater, or ditches, or in some cases wells. None of these consume marketed energy at anything like the rate given above for tap water. (Wells often need water pumps, but the energy use of the pump is tiny compared to a municipal potable water system.)
