想知道洗澡用了多少水?谷歌新工具来帮忙

Natasha Bach 2018年09月13日

最近,谷歌联手加州科学博物馆推出了一款新工具,以此希望可以帮助用户计算用水量,并提出省水方案。

想知道淋浴用了多少水,或者丢弃食物的影响吗?

上周五,谷歌联手加州科学博物馆推出了一款新工具,叫Your Plan, Your Planet,希望帮用户找到问题的准确答案。

互动工具覆盖能源、水和食品用量三大领域,提出相关领域的多种问题,比如淋浴的时长、每天家中开灯多长时间。然后判断用户的年度用量,提供节约能耗的建议。

例如,用热水洗衣服耗用的能源是冷水洗的十倍。假如每周用热水洗衣三次,一年将用电708千瓦时,产生的二氧化碳和一辆汽车行驶18小时的排放量相当。而如果每周用冷水洗三次衣服,一年仅用电62千瓦时,等于一辆车行驶两小时的二氧化碳排放量。

美国家庭平均每日用水300加仑(约1.14立方米),一年用量足够灌满三个泳池。其中淋浴最费水,假如每天淋浴十分钟,一年用水将超过9000加仑(约合34立方米),可以灌满31个户外热水浴池。

食物浪费也是个大问题。生产食品耗水量占全球用水总量的三分之二以上,产生的二氧化碳几乎占总排放量的四分之一。为了降低相关能耗,该应用列举了多个储存食品的诀窍,帮助人们尽可能在保质期内消耗掉冰箱内储存的食物。(财富中文网)

Ever wondered how much water your shower uses? Or the impact of throwing away your food?

Google launched a new tool on last Friday with the California Academy of Sciences, called Your Plan, Your Planet, which hopes to help you answer precisely those questions.

The interactive tool covers three areas: energy, water, and food usage. It asks questions about your usage on everything, from the length of your shower to how many hours a day you keep lights on in your home. It then uses that information to determine your annual use and provide tips for more efficient use.

For example, washing your clothes in hot water uses ten times the energy of washing in cold. A person who does three loads of laundry per week in hot water uses 708 kilowatt hours of energy annually, creating the carbon dioxide equivalent to driving a car for 18 hours. The same number of loads washed in cold uses just 62 kilowatt hours of energy annually, equivalent to driving a car for two hours.

The average American family uses 300 gallons of water each day—enough water to fill three swimming pools in a year. And showers are one of the big culprits: a 10 minute shower uses over 9,000 gallons of water in a year. That could fill 31 hot tubs.

Food waste is also a major problem. Food production uses more than two-thirds of the world’s water and accounts for almost one-fourth of carbon dioxide equivalent use. To offset this, the tool outlines a number of food storage tips that will help maximize the lifespan of the items you have in your fridge.
