What more can we do？Here’s how：

Replace a regular incandescent light bulb with a compact fluorescent light bulb (CFL)。 把一般的白炽灯泡取下，换上小型化荧光灯(大陆称“紧凑型节能灯”) 。 CFLs use 60% less energy than a regular bulb.This simple switch will save about 300 pounds of carbon dioxide a year。 小型化荧光灯比起白炽灯泡更能节省百分之六十的耗电量，而这样简单的更换举动一年可省下三百磅的二氧化碳的消耗量。

Move your thermostat down 2°in winter and up 2°in summer。 冬天时把你的温度调节器调降两度，夏天则升两度。

Clean or replace filters on your furnace and air conditioner。清洗或换掉暖炉及冷气机的空气滤清器。 Cleaning a dirty air filter can save 350 pounds of carbon dioxide a year。 清理肮脏的空气滤清器一年可以省下三百五十磅的二氧化碳。

Install a programmable thermostat。 安装可编排程序的调温器。

Choose energy efficient appliances when making new purchases。 当购买新产品时，买最节省能源的。 You'll save 1,000 pounds of carbon dioxide a year with this simple action。You can save another 550 pounds per year by setting the thermostat no higher than 120 degrees Fahrenheit。 简单的动作一年就能省下一千磅的二氧化碳。你还可以把沸腾后的温度设定成不超过华氏一百二十度(摄氏四十九度)，这样一年又能省下五百五十磅。

Use less hot water。 少用热水。 It takes a lot of energy to heat water.You can use less hot water by installing a low flow showerhead (350 pounds of carbon dioxide saved per year) and washing your clothes in cold or warm water (500 pounds saved per year) instead of hot。 把水加热是很花能源的。你可以装个低一点的莲蓬头，就可以少用些热水(一年可省三百五十磅)还有用冷水或温水洗衣服，而不是用热水来洗(一年可省五百磅)。

Use a clothesline instead of a dryer whenever possible 多用晒衣绳，而非干衣机。 You can save 700 pounds of carbon dioxide when you air dry your clothes for 6 months out of the year。 一年有超过六个月都用风干衣服的方式，就能节省七百磅的二氧化碳。

Turn off electronic devices you're not using。 不用电子装置时就关机吧。 Simply turning off your television,DVD player,stereo,and computer when you’re not using them will save you thousands of pounds of carbon dioxide a year。 当你不用电视、DVD、音响及计算机时，只要把电源关了一年就能节省上千磅的二氧化碳。

Unplug electronics from the wall when you're not using them。 不用的时候就把插头拔了。 Even when turned off, things like hairdryers,cell phone chargers and televisions use energy. In fact, the energy used to keep display clocks lit and memory chips working accounts for 5 percent of total domestic energy consumption and spews 18 million tons of carbon into the atmosphere every year! 即使关了机，例如吹风机、手机充电器及电视都仍在使用能源。事实上，能源用在显示警示灯及运作记忆芯片上约占了总家庭能源消耗的百分之五，也因此每年有一百八十亿吨的二氧化碳被排放到空气中！

Only run your dishwasher when there's a full load and use the energy-saving setting。 洗碗机只能在满载时运作，并设定成节能状态。 You can save 100 pounds of carbon dioxide per year。 一年可省下一百磅的二氧化碳。

Insulate and weatherize your home。 让房子加强绝缘及御寒能力。

Be sure you’re recycling at home。 在家确实做好分类。 You can save 2,400 pounds of carbon dioxide a year by recycling half of the waste your household generates. 回收半数家里制造的垃圾可以让你一年节省两千四百磅的二氧化碳。Buy recycled paper products。 购买用回收纸制造的产品。 It takes less 70 to 90% less energy to make recycled paper and it prevents the loss of forests worldwide。 制造回收纸会减少百分之七十到九十的能源浪费，而且也能预防全球性的森林大量流失。

Plant a tree。 种棵树吧。 A single tree will absorb one ton of carbon dioxide over its lifetime.Shade provided by trees can also reduce your air conditioning bill by 10 to 15%。 一棵树在它的有生之年能吸收一吨的二氧化碳。树荫也能减少十到百分之十五的冷气费用。

Get a home energy audit。 去拿张家庭节能审查单回家吧。

Switch to green power。 改用绿色能源吧。 In many areas, you can switch to energy generated by clean,renewable sources such as wind and solar.The Green Power Network is a good place to start to figure out what’s available in your area。 在许多地方，你可以改用由干净、再生的资源所生产出的能源，比如说风力和太阳能。绿色能源网络可以让你知道，什么是在你的区域内适用的能源。

Buy locally grown and produced foods。 买当地出产的食物。

Buy fresh foods instead of frozen。 买生鲜食品，而非冷冻的。 Frozen food uses 10 times more energy to produce。 冷冻食品需要用上的能源，比制造生鲜产品还要多上十倍。

Seek out and support local farmers markets。 找到当地农友市场，并多加支持。 They reduce the amount of energy required to grow and transport the food to you by one fifth.You can find a farmer’s market in your area at the USDA website。 在让作物生长及运送过程上，他们减少了五分之一的能源用量。你可以在USDA网站找到当地的农友市场。

Buy organic foods as much as possible。 尽可能买有机食品。 Organic soils capture and store carbon dioxide at much higher levels than soils from conventional farms.If we grew all of our corn and soybeans organically,we’d remove 580 billion pounds of carbon dioxide from the atmosphere! 有机土地比传统的农业用地更能储存及吸收二氧化碳。假若我们种植有机玉米跟豆类，就能去除空气中五千八百亿磅的二氧化碳量！

Avoid heavily packaged products。 别拿过度包装的产品。 You can save 1,200 pounds of carbon dioxide if you cut down your garbage by 10%。 如果你垃圾减量百分之十，就能省下一千两百磅的二氧化碳。

Eat less meat。 少吃点肉。 Methane is the second most significant greenhouse gas and cows are one of the greatest methane emitters.Their grassy diet and multiple stomachs cause them to produce methane, which they exhale with every breath. 甲烷是第二项主要造成温室效应的气体，而牛只就是最常排放甲烷的其中之一。因为它们的草食习惯及多个胃囊，导致它们在每次呼吸间就会排出甲烷。

Reduce the number of miles you drive by walking,biking,carpooling or taking mass transit wherever possible。 可能的话多走路、骑脚踏车、共乘、搭大众运输来减少开车的里程数。 Avoiding just 10 miles of driving every week would eliminate about 500 pounds of carbon dioxide emissions a year! Click here to find transit options in your area. 每个礼拜只要少开十哩，一年就能减少约五百磅的二氧化碳排放量！点这来查询你当地的公共交通运输项目。

Start a carpool with your coworkers or classmates。 开始和你的同事或同学共乘台车。 Sharing a ride with someone just 2 days a week will reduce your carbon dioxide emissions by 1,590 pounds a year. 一个礼拜只要两天和人共乘，一年就能减少一千五百九十磅的二氧化碳排放量。

Keep your car tuned up。 时常保养车子。 Regular maintenance helps improve fuel efficiency and reduces emissions.When just 1% of car owners properly maintain their cars,nearly a billion pounds of carbon dioxide are kept out of the atmosphere. 规律的保养可帮助提升用油效能及减少废气排放。只要有百分之一个车主能正确的保养车子，就能节省将近十亿磅的二氧化碳排放到空气中。

Check your tires weekly to make sure they're properly inflated。 每个礼拜检查轮胎，并确认胎压是否适当。 Proper inflation can improve gas mileage by more than 3%.Since every gallon of gasoline saved keeps 20 pounds of carbon dioxide out of the atmosphere,every increase in fuel efficiency makes a difference! 适当的胎压可以让行驶哩数比平常多过百分之三。因为每省下一加仑的汽油就能省下二十磅二氧化碳的排放，一旦增加利用燃料的效能就有所不同！

When it is time for a new car,choose a more fuel efficient vehicle。 该买台新车时，选辆最省燃料的吧。 You can save 3,000 pounds of carbon dioxide every year if your new car gets only 3 miles per gallon more than your current one.You can get up to 60 miles per gallon with a hybrid! You can find information on fuel efficiency here and here。 假如你的新车每加仑可比你原先买的车多跑三哩，你每年就能省下三千磅的二氧化碳。你甚至可以买台油电车，一加仑可跑六十哩！

Try car sharing。 试着一起买车。

Fly less。 少搭机。 Air travel produces large amounts of emissions so reducing how much you fly by even one or two trips a year can reduce your emissions significantly.You can also offset your air travel by investing in renewable energy projects。 搭机旅行会排放大量的二氧化碳，所以减少搭机频率，即便只有一两次都能对于降低废气排放有很重大的影响。你也可以去投资再生能源计划好在未来能取消搭机旅行。
