Today marks the 40th anniversary of 地球日. 你将如何度过这一天？ 这里有一些简单的方法来节约能源，减少你对地球的影响。

创造你自己的地球一小时
During 地球一小时活动, people around the world turn off the lights. 甚至像埃菲尔铁塔和帝国大厦这样的著名景点也会变黑。 今晚，关掉电灯和电视，重新创造你自己的地球一小时。 在烛光下玩棋盘游戏，吃晚餐或看书。

调整你的恒温器
春天慢慢变热，进入了夏天。 检查你的供暖和制冷设置是否适合新季节。

使用紧凑型荧光灯（cfl）
If you haven’t already made the switch, think about replacing old light bulbs with CFLs. According to 能源之星的级别, if each home in America replaced just one light with an ENERGY STAR light, the energy saved would light more than 3 million homes for a year and save about $700 million in annual energy costs.

减量、再利用、再循环、再循环
升级回收是一种把垃圾变成有用东西的艺术。 Do you have a basement full of items that you're thinking about throwing away? Next time you want to run to the store to buy something new, head down to your stash and envision if there’s anything there that you could use instead, like this pair of rubber boots that became a flower pot.
