首先maintain ,retain和sustain 有各自不同的意思,但其中都有“保持、维持”的意思.这三个词的区别要从各个词的原始（original）意思上去体会细微的意思差别.
maintain --keep sth.in existence at the same level,standard.维持（已有的水平、标准）如：
I hope you will maintain your recent improvement.我希望你能保持最近取得的进步.
Let's maintain peace in the world.让我们来维持世界和平.
maintain law and order维持治安
maintain prices保持价格稳定
retain--keep sth.in one's possession or use.保留 如：
This village still retains its old world character.这个村庄仍然保持着古色古乡特色.
We retained the original fireplace when we decorated the room.我们装修那个房间时,原来的壁炉保留不动.
This cloth retains its color.这布不褪色
He is 90 but still retains (the use of)all his faculties.他年已九旬,但各种官能仍未衰退.
sustain --keep sb./sth.alive or in existence（支持、维持生命）,to keep up the strength,spirits or determination of （维持体力/精神/决心）如：
The supplies of food were scarcely enough to sustain life.食品的供应仅够勉强维持生命.
A light meal won't sustain us through the day.一顿小食维持不了我们一天的精力.
Hopes alone sustained him in his misery.他在痛苦之中只有希望鼓励着他.
现代英语中也有互用的情况.如：
我们也看到“enough food to maintain one's stength”这样的句子.这时maintain =sustain .

conserve的词根serve有keep（保留）之意,派生出conserve（保护,保存）；preserve(维护,保存)；reserve（保留,储备；预定）等词.这些词可以联系对比进行记忆.用词根来记忆可以帮助记住系列词汇,值得尝试.

Reserve比较常见,是指为“留作后用”的保留、预订,可指保留座位、权利、意见等等,.
Conserve侧重“为了减少浪费”而进行的保护,而且强调对有价值的东西非常珍惜,并合理的使用 .
Preserve则不光是只「保留」,还强调保留下来「收藏」,使东西完好无损,侧重“为了不至于灭绝、损坏”而进行的保护.

前者倾向保护,后者倾向保存

A lot of the energy we use at home,at school,and for our cars comes from fossil fuels like coal,oil,and natural gas.The earth has only a limited amount of these fuels and humans are using them up very fast.From this point,it is beneficial to conserve resources,as illustrated by the following three respects.
First of all,to conserve resouces requires us to save energy we use,thus saving money we spend.In this way,the money saved can contribute to the conservation of the resources,and this in return can benefit the conservation of the resources and other welfare.
Also,the conservation of resouces is beneficial to the health of human being.By conserving resouces,we can reduce the energy we use,and then reduce the amount of air pulllution produced by the burn of energy.Thus,it is obvious that to conserve resouces is beneficial to the health of human being.
Last but not the least,by saving energy,we can slow down the use of fossil fuels and make our supplies last longer.For our future,it is necessary for us to conserve resources.
In conclusion,we can savely arrive at the position that it is beneficial to conserve resources for the above-mentioned reasons.

字面上的意思是 保存你的能量
根据上下文不同,有不同的意思
1.如果你在比赛,意思是"保存实力"
2.如果你一味地做一些吃力不讨好的事,意思是"省省吧"
.

1. Protect Wildlife Habitat
2. Join a Conservation Organization
3. Reduce the Threat of Invasive Species
4. Recycle and Reduce Energy and Goods Consumption
5. Minimize use of Herbicides and Pesticides
6. Place Decals on Windows to Deter Bird Collisions

8. Voice Your Concerns and Get Involved Locally
9. Change Your Career
10. Share Your Enthusiasm for Wildlife and Nature

这两个都是地道的的.但是你要主要单复数,正确的形式是：
Save resources
conserve resources

个人观点,对于这几个词的理解关于在于字根：
conserve：强调con词根,表示时间永远的意思；
preserve：强调pre词根,表示提前的意思；
reserve:强调re词根,表示“重复”“再次”保留的意思.
contain与前几个词的记源不一样,更强调获取并保留的意思.

Reserve

想要真正理解英语单词意思还得多学学希腊神话故事，很多单词都是从希腊神话中演变过来的，当然不能只从词根来翻译中文意思。而且前缀和后缀都是帮助你理解单词意义的，而不是单纯的翻译成能与汉语意思匹配的一般要知道单词的意思先看前缀，前缀帮你理解单词意思，后缀帮你判断词性。
