How A Dishwasher Works

Inside of a Dish Washer

Water Efficiency

This is great, and certainly caters to my want to be told that it's more energy efficient to be lazy. I'm convinced that using a dishwasher is more water efficient than hand washing, unless you are hand washing and then trapping your water for use in watering plants or flushing the toilet (which a few people I know do). Of course, best of all would be to trap the water from the dishwasher and use the grey water on plants or to flush the toilet.

But… I'm not convinced about energy yet.

用水效率

這是偉大的，無疑迎合了我的旺旺被告知是很少節能偷懶。我相信，使用一台洗碗機，更高效的煤水洗手，除非你是洗手，然後使用捕獲你的水沖洗馬桶或澆花（我知道的幾個人做的）。當然，最重要的是將捕獲從洗碗機的水和植物上使用灰水或沖洗廁所。
但是...我還不相信對能源。
