14.9 节能
Section outline
-
You won’t see this car on the road, at least not yet. It’s a concept car that was developed by a major automaker. Instead of burning gasoline, it runs on hydrogen . Using hydrogen for fuel doesn’t produce pollution, and it doesn’t depend on nonrenewable fossil fuels . New technologies like this car may one day help solve our resource problems. But even without new technologies such as this, there are many ways we can help solve the problems right now.
::你看不到这辆汽车在路上,至少现在还看不到。 它是一个由主要汽车制造商开发的概念汽车。 它不是燃烧汽油,而是在氢上运行。 使用氢燃料不会产生污染,也不依赖不可再生的化石燃料。 这样的新技术也许有一天会帮助解决我们的资源问题。 但是,即使没有这样的新技术,我们现在也有很多方法可以帮助解决问题。Conserving Energy
::保护能源Everyone can reduce their use of energy resources and the pollution the resources cause by conserving energy. Conservation means saving resources by using them more efficiently, using less of them, or not using them at all. You can read below about some of the ways you can conserve energy on the road and in the home.
::人人都可以通过节能来减少对能源的利用,减少对能源的污染。 节能意味着通过更有效地使用能源来节约资源,减少能源的使用,或者根本不使用能源。 下面可以读到一些如何在公路上和家里节能的方法。Conserving Energy in Transportation
::运输中的节能能源Much of the energy used in the U.S. is used for transportation. You can conserve transportation energy in several ways. For example, you can:
::美国大部分能源用于运输。您可以通过多种方式节约运输能源。例如,您可以:-
plan ahead to avoid unnecessary trips.
::提前计划,以避免不必要的旅行。 -
take public transit such as subways (see
Figure
) instead of driving.
::乘坐地铁等公共交通工具(见图),而不是驾驶。 -
drive an energy-efficient vehicle when driving is the only way to get there.
::驾驶节能车辆是到达那里的唯一办法。
Q: What are some other ways you could save energy in transportation?
::问:在运输中,还有什么其他节约能源的方法?A: You could carpool to save transportation energy. Even if you carpool with just one other person, that’s one less vehicle on the road. For short trips, you could ride a bike or walk to you destination. The extra exercise is another benefit of using your own muscle power to get where you need to go.
::甲:你可以用汽车来节省交通能源。即使你只和另一个人一起用汽车,这在路上也比这少了一辆汽车。 对于短期旅行,你可以骑自行车或步行到目的地。 额外练习是利用自己的肌肉力量到达你需要去的地方的另一个好处。Conserving Energy at Home
::国内节能能源Many people waste energy at home, so a lot of energy can be saved there as well. What can you do to conserve energy? You can:
::许多人在家中浪费能源,所以在那里也能够节省大量能源。你能为节能做些什么?你可以:-
turn off lights and unplug appliances and other electrical devices when not in use.
::在未使用时,关闭灯光和脱插件及其他电气设备。 -
use energy-efficient light bulbs and appliances.
::使用节能灯泡和电器。 -
turn the
thermostat
down in winter and up in summer.
::冬天调温器 冬天调温器 夏天调高
Q: How can you tell which light bulbs and appliances use less energy?
::问题:你如何知道哪些灯泡和电器使用较少能源?A: One way is to look for this ENERGY STAR® logo ( Figure ).
::A: 一种方法是寻找ENERGY STARQ 标志(图)。Watch the video below to learn more about :
