Maybe because it's 25C cooler than 25C water. Takes more energy to convert to steam. I guess.

- rightbyte 6y agoMy point is: Water 1c change is 4184 J/kg (1 kcal) Water to steam 2260 kJ/kg. So 25c cooler is 25 * 4.184 kJ extra, which is: 25 * 4184 / (2260k + 75 * 4184) = 104600 / 2573800 => 4% more energy than 25c to steam. And then you need a refrigerator to cool tons of water, instead of just carrying more water.
