按照现在的消费速度，全世界需要每小时竖起24个风力涡轮机，才能生产足够取代矿物燃料的能量。

At current rates of consumption, the world needs to erect 24 wind turbines an hour to produce enough energy to replace fossil fuel.

最近，工厂的两个团队分别提出了两种加快擦洗涡轮机叶速度的提议。

Recently, two teams came up with different ways to speed up the washing of turbine blades.

涡轮在高速运行的时候效率更高，而风扇在低速时效率更高，因此涡扇发动机需要在这两者间达到拖鞋，因为发动机的设计需要他们以相同的速度运行。

Turbines run most efficiently at high speeds, and fans at low speeds, so turbofan engines have to compromise between the two, because the engine's design requires them to turn at the same speed.
