Another proposal is to subsidise the cost of installing LED lighting in place of incandescent and fluorescent lamps, which would mean energy savings of 80% and 50% respectively.

另一种构想是，提供补贴以鼓励安装LED灯来取代白炽灯和荧光灯，这意味着各节省80%和50%的能源。

And specifically, when we talk about ionization energy, it's assumed that what we mean is actually the first ionization energy.

特别地，当我们讨论电离能的时候，我们默认,这指的是第一电离能。

I mean we can, we can sort of understand why OK, the total energy, if we measure it, we measure a process which is not reversible.

例如我们易于理解为什么，当试图测量一个不可逆系统的总能量，给出的或许。

It could also be that employers continue to hold on doggedly to trained and trusted staff, still hoping for the upturn, while some areas of the economy - in London, it was the Olympics, in Scotland, that tends to mean energy - have their own reasons for continuing to expand.
