2-- That's excellent. How have you managed that?
 
1-- Mainly because we've invested in a heat recovery system.
 
2-- What does that mean exactly?
 
1--Well, we use the exhaust gases from our printing presses to provide energy to heat our dryers.
 
2--What other sources of energy do you use?
 
1-- We don't use any fossil fuels. Most of our power comes from hydro-electric plants. We're hoping to use even more energy from alternative sources in the future - perhaps even wind power.

1--在过去的两年内我们已经努力把我们厂的能量消耗降低百分十五。
2--那太好了。你们怎么做到的？
1--主要因为我们投资建了一个热量回收系统。
2--那确切的是指什么？
1--哦，我们利用我们的印刷机排出的废气为能源来加热我们的干燥剂。
2--你们使用的其他能量来源于什么？
1--我们不使用任何矿物燃料。我们的大部分电力来自于水电站。我们希望在将来更多的使用可替代能源，也许会使用风电。
