压缩空气发电站效率不高，因此它只有在电价波动大的地方才具有商业可行性。
Compressed-air plants are inefficient, and so they are commercially viable only in places where the price of power varies dramatically.
随着全球变暖趋势不断增加，多数人都在寻求提高效率和节约能源——从而减少发电站的温室气体排放。
With global warming an ever increasing issue, most people are looking for ways to improve efficiency and save energy - and therefore reduce power-station emissions of greenhouse gases.
同大多数富国一样，英国燃煤发电站的平均燃烧效率在35%左右。
In Britain, as in most rich countries, the average efficiency of coal-fired power stations is about 35%.
多数借由提升燃烧效率带来的利益是依靠对用以驱动发电站涡轮机的蒸汽进行升温和加压。
Most of the gains in efficiency come from increasing the heat and pressure of the steam used to turn a plant's turbines.
当我们谈论新陈代谢时，我们真正讨论的是发电站单元-身体的肌肉细胞-燃烧的效率如何。
And when we talk about metabolism, what we're really talking about is how efficiently those powerhouse cells - the muscle cells of our body - burn the energy we bring in.
虽然用熔融盐储存热量的技术在别的发电站已经在使用了，但是Torresol将它的效率提升到了一个新的高度。
Although molten salt has been used in other plants to store heat energy, the efficiency achieved by Torresol is new.
例如，因为温度的不断增高，变压器可能出现较高的失效率，而某些类型的火力发电站的效能也可能会显著的降低。
For instance, transformers could suffer higher failure rates and efficiency of some types of thermal power station could be markedly reduced because of increasing temperatures.
现在发达国家的水力发电效率基本上达到极限了，这意味着如果没有新的水力能源形式利用，在未来就不会有任何水力发电站需求。
Most hydro systems in the western world have been exploited to their full potential, which means that future demand will not be satisfied by hydro unless new hydro energy forms become available.
为了满足中国新电网而疯狂建造中的电力站与其他国家老式煤炭发电站相比效率较高，污染较小。
The power stations frantically being built in China to feed the country's new electricity grid will be relatively efficient and thus less polluting than older coal plants around the world.
