A study into the habits of British families has found that some "power showers" use twice as much water as the average bath, the Daily Mail reported.

While an average bath uses 80 liters of water, some power showers can use up to 136 liters of water for an eight-minute wash. That is comparable to 200,000 liters of hot water per year for a four-person family, at a cost of 918 pounds in water and electricity.

The findings threaten to debunk the "eco-myth" that a shower is always the greenest option.

据英国《每日邮报》报道，一项针对英国家庭生活习惯的调查研究发现，一些人冲凉所耗费的水竟然是泡澡平均用水量的2倍。

泡澡所用的平均水量有80升，而用电热水器仅冲凉8分钟就要用136升水。这意味着，一个四口之家每年能用20万升热水，需水电费918英镑。

这一研究结果打破了冲凉是最绿色的“节能神话”。
