想知道淋浴用了多少水，或者丟棄食物的影響嗎？

上周五，谷歌聯(lián)手加州科學博物館推出了一款新工具，叫Your Plan, Your Planet，希望幫用戶找到問題的準確答案。

互動工具覆蓋能源、水和食品用量三大領域，提出相關領域的多種問題，比如淋浴的時長、每天家中開燈多長時間。然后判斷用戶的年度用量，提供節(jié)約能耗的建議。

例如，用熱水洗衣服耗用的能源是冷水洗的十倍。假如每周用熱水洗衣三次，一年將用電708千瓦時，產(chǎn)生的二氧化碳和一輛汽車行駛18小時的排放量相當。而如果每周用冷水洗三次衣服，一年僅用電62千瓦時，等于一輛車行駛兩小時的二氧化碳排放量。

美國家庭平均每日用水300加侖（約1.14立方米），一年用量足夠灌滿三個泳池。其中淋浴最費水，假如每天淋浴十分鐘，一年用水將超過9000加侖（約合34立方米），可以灌滿31個戶外熱水浴池。

食物浪費也是個大問題。生產(chǎn)食品耗水量占全球用水總量的三分之二以上，產(chǎn)生的二氧化碳幾乎占總排放量的四分之一。為了降低相關能耗，該應用列舉了多個儲存食品的訣竅，幫助人們盡可能在保質(zhì)期內(nèi)消耗掉冰箱內(nèi)儲存的食物。（財富中文網(wǎng)）

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.
