Electriccarsaredirty.Infact,notonlyaretheydirty,theymightevenbemoredirtythantheirgaso...
Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.
People in California love to talk about “zero-emissions vehicles,” but people in California seem to be clueless about where electricity comes from. Power plants most all use fire to make it. Aside from the few folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something — usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal plants as well, but by far we get electricity mainly by burning something.examda.com
In other words, those “zero-emissions” cars are likely coal-burning cars. It's just the coal is burned somewhere else so it looks clean. It is not. It’s as if the California Greens are covering their eyes — “If I can’t see it, it’s not happening.” Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat — at the generator, through the transmission lines, etc.
A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far — so electric cars burn more fuel than gas-powered ones. If our electricity came mostly from nukes, or geothermal, or hydro, or solar, or wind, then an electric car truly would be clean. But for political, technical, and economic reasons, we don’t use much of those energy sources.
In addition, electric cars’ batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it’s a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are not too concentrated, but it takes a lot longer when all the garbage is in one spot. 展开

电动汽车是脏的。事实上,他们不仅是肮脏的,他们甚至有可能比他们更脏汽油动力堂兄弟。
人在加利福尼亚州的爱谈论“零排放车辆” ,但在加州的人似乎是束手无策的地方电力来自。电厂大部分都用火,使之。除了少数几个人谁也屋顶布满太阳能电池,我们得到我们的电力发电机。发电机燃料的东西-通常是煤炭,石油,而且产生的热量在核电厂。有几个风力发电和地热等植物,以及,但迄今为止我们得到的电力主要由燃烧something.examda.com
换言之,这些“零排放”的汽车有可能煤燃烧的汽车。这仅仅是煤炭燃烧别的地方看起来干净。事实并非如此。这是因为如果加州果岭覆盖他们的眼睛- “如果我看不到,也不会发生。 ”汽油是一个难以置信的有效途径权力车辆;一加仑汽油有很多能源它。但是当你采取这一天然气(或其他燃料)和第一次使用它来发电,你浪费了很好的一部分,能源,主要形式是浪费热-在发电机通过输电线路等
交货的轻质可推动您的汽车25英里。但是,电力你从加仑汽油将不会让你近远-这样的电动汽车消耗更多的燃料比天然气动力的。如果我们的电力大部分来自核武器,或地热,或水力发电,或太阳,或风,那么电动车真正将清洁。但是,对于政治,技术和经济方面的原因,我们不使用这些大部分能源。
此外,电动车的电池是有毒了很长一段时间将最终结束在一个垃圾填埋场。最后,当汽车的污染,污染遍布所有道路。当这是一个发电厂,不过,所有的垃圾是在同一个地方。大自然是非常好的在清理时,事情是不能过于集中,但要花很多不再当所有的垃圾放在同一个位置。

使你开心或者不开心的不是你拥有什么或者你是谁,也不是你在哪儿或者你正在做什么。而是你是怎么认为的。
比方说,两个人也许正在同一个地方做着同一件事,两个人都有大致相同数目的钱和声望,但是其中一个可能痛苦而另一个却快乐。这是为什么呢?因为心态不同。

不是因为你拥有什么,你是谁,你在哪里,或者你在做什么让你快乐或者不快乐。这是由于你怎样看待它。例如,两个人可以在同一个地方,做同样的事,都可能有大约一样的金钱和声望,一个可能是悲惨另一个是快乐的。为什么呢?因为有不同的精神状态

是你自己的想法态度而不是你所拥有的,你的身份,你身处的地方或者你正在做的事决定了你的快乐或者不快乐。例如,两个人可以在同一个地方,做同样的事,可能有相等的财产和声望,一个欢欣雀跃,另一个却愁眉苦脸。这是为什么?因为他们用不同的心态面对生活。

并不是你拥有什么,你是谁,你在哪里,或者你做了些什么就能决定你的快乐或者不快乐,而是你怎么去想他,比如说两个人在同一个地方做着同样的一件事,两个人有一样多的钱和荣耀,一个人很不幸而另一个人却很快乐,为什么呢?因为不同的思想态度
