For the lasttwo centuries we have been u—
s|ng more and more coal,oil and gas.These fuels
wIII not last forever.The problem has been tO find
a waY tO use the tremendous power wh ich the
earth receives from the sun every day.Not OnIV is
the sun now used for cooking,but it also supplies
power fOr such things as beacon lights for ships
and aIrplanes-It operates telephone lines,mOvie
cameraS,electric clocks,and hearing aids.SOme
homeS and office buildings in the United States
are nOw being heated with solar energy.Solar
stills are especially important because they can
p rOvIde fresh water fairly cheaply.They can rapidly
take the salt out of sea water.
I he most highly developed and most useful
type of solar power equipment is the solar ceII.
One of the cell’s biggest advantages is that it can
be made small enough to carry.It can aIso be
made large enough to produce enough power tO
run a car·Another advantage of the solar ceIi is
that It has a very long life.It is still very expensive.
but when ways are discovered to produce it mOre
cheaply,It will be used very widely.The envirOn.
ment will be much cleaner then.
在过去的两个世纪里,我们使用了越来越多的煤、石油和天然气.这些燃料是不能永远使用的.现在的问题是找到一种方式来使用每天地球从太阳那里得到的大量的能源.太阳现在不仅被用来做饭,而且能提供能源给其他的东西,比如船只和飞机使用的灯塔——太阳能用来运行电话线路,电影摄像机,电子钟表以及助听器.美国的一些家庭和办公建筑现在正在使用太阳能来进行取暖.太阳能蒸馏器尤其重要,因为他们能够相对便宜的提供淡水.他们能够快速的把盐从海水中去除.
发展程度最高的,也是最有用的太阳能设备是太阳能电池.这种电池的最大优势之一是能够被造的足够小,方便携带.它也可以被造的足够大,以产生足够的能量驱动一辆汽车.太阳能电池的另外一个优势是寿命很长.这种电池现在还很昂贵,但是当更便宜的生产太阳能电池的方法被发现后,这种电池将被广泛使用.环境就会变得清洁的多.
