通常这种热-电转化方式是利用热电偶实现的。 热电偶由两层不同的金属构成，其中一层比另一层温度高时就在两层金属间产生电流。
The usual way to do this is with a thermocouple—a sandwich of two metals that produce a current when one side of the sandwich is hotter than the other.
报告非常恰当地确定了热电联合系统——也就是说，既利用由燃烧农作物而产生的热能也利用电能所产生的热——利用当地种植的能源农作物是降低温室效应气体排放的最有利的方法。
The report correctly identifies CHP - that is using the heat produced from burning as well as the electricity - with locally grown energy crops as the best way to reduce greenhouse gas emissions.
Blue - NG，一家开发英国项目的合资公司，打算使用搭配涡轮放大器的同时，搭配上能产生电和热的热电联产发动机，从而达到削减成本的目的。
Blue-NG, the joint venture developing the UK projects, aims to reduce costs by combining the turboexpander with a combined heat and power (CHP) engine, which generates both electricity and heat.
