六级Unfortunately for them ( ' , and often the taxpayers), our energy systems are a bit like an aircraft carrier: they are unbelievably expensive, they are built to last for a very long time, they have a huge amount of inertia ( ' , meaning it takes a lot of energy to set them moving), and they have a lot of momentum once they are set in motion.

不幸的是，对他们（通常是纳税人）来说，我们的能源系统有点像一艘航空母舰：它们的价格高得令人难以置信，它们的建造寿命很长，它们有巨大的惯性（这意味着需要大量的能量才能使它们移动），一旦它们启动，它们就有很大的动力。

六级When you hear people speaking of making a rapid transition toward any type of energy, whether it is a switch from coal to nuclear power, or a switch from gasoline-powered cars to electric cars, or even a switch from an incandescent to a fluorescent light, understanding energy system inertia and momentum can help you decide whether their plans are feasible.

当你听到人们谈论向任何类型的能源快速过渡时，无论是从煤炭到核能的转换，还是从汽油动力汽车到电动汽车的转换，甚至是从白炽灯到荧光灯的转换，了解能源系统的惯性和动量可以帮助你决定他们的计划是否可行。
