Thanks to a 30% federal tax credit, that works out as much the same as a combined-cycle gas-turbine plant-but without the noise and fumes.

这和我们国家用30%的税收建成的一座联合涡轮燃气发电厂的产能一样，不同的是，人家不产生噪音和废气。

The efficiency of a coal-fired thermal plant is typically in the range of 30%-35%. In a combined cycle gas turbine system running on natural gas, the maximum efficiency is in the range 45%-50%.

烧煤的热电厂的效率通常在30%到50%之间，使用天然气的联合循环燃气轮机系统最大效率在45%到50%之间，而很多专家认为高温燃料电池的效率可达到80%至85%。
