当一个光伏阵列被树木或房屋等物体遮挡住时，太阳能电池中会发生电子堆积现象，好似在交通阻塞中的汽车一样，因而电流减弱。
When a PV array is shaded by another object, like a tree or a house, the solar panels get backed up with electrons like cars in a traffic jam, and the current drops.
消极供暖房屋将太阳能转化为热能的原理与封闭的汽车一样：阳光穿过窗户然后被墙壁和地面所吸收。
A passive solar home converts solar energy into heat just as a closed car does. Sunlight passes through a home's Windows and is absorbed in the walls and floors.
如果电能来源于煤，那它们仍然比传统汽车有优势——但是如果该电能来源于风能、太阳能甚至是(最好别是)核能，那优势就没有多少了。
If it comes from coal, they are still better in global-warming terms than traditional cars-but not by as much as they could be if the power were wind, solar or even (whisper it not) nuclear.
这是装进电动汽车的电池，这种电池最终会使用太阳能或者风能，能够以一种有效方式加以转化。

In particular, the Department of Energy frets about certain metals used in manufacturing wind turbines, electric vehicles, solar cells and energy-efficient lighting.
解决办法包括排污量更小的汽车和更好的风能和太阳能技术。
Solutions include cleaner cars and better wind- and solar-power technologies.
透明的太阳能电池通过背景光发电，然后进行水电解产生氢来驱动汽车。
Transparent solar cells generate electricity from ambient light. This electricity is used to carry out electrolysis of water and generate hydrogen to fuel the car.
可以想见，那些来自于拥有大量汽车工厂和煤矿而仅有少量风能和太阳能的州的国会议员们会支持这一举措。
Predictably, congressmen from states with car factories and coal mines, and not much wind or sunshine, agree.
布赖森是太阳能电池板公司亮源能源(BrightSource Energy)的董事长，并担任制造电动汽车的Coda Automotive的董事。
He is chairman of Brightsource Energy, a solar panel group, and sits on the board of Coda Automotive, which makes electric vehicles.
由于新的环保条例的出台（如太阳能电池板和电动汽车），和受到新兴市场的快速膨胀（如医疗器械和生物医药）的影响，前面提到的领域都会得到飞速发展。
They are about to grow rapidly, thanks to new environmental rules (solar power, LED lights and electric cars) or exploding demand in emerging markets (medical devices and drugs).
但是，建太阳能电池板工厂比建汽车总装厂快，也要比建汽车总装厂容易。这能允许太阳能制造商迅速做出反应。
But setting up solar panel factories is faster and simpler than building a car assembly plant, which could allow Chinese solar power manufacturers to respond quickly.
你怎样才能说服他们相信太阳能汽车的长处呢？
