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.

據英國《每日郵報》報道，一項針對英國家庭生活習慣的調查研究發現，一些人沖涼所耗費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，而用電熱水器僅沖涼8分鐘就要用136升水。這意味著，一個四口之家每年能用20萬升熱水，需水電費918英鎊。

這一研究結果打破了沖涼是最綠色的“節能神話”。
