充分利用煤

美国依靠煤炭产生一半以上的电力，很显然，可再生能源的采用将是一个缓’幔过程。与此同时，科学家们正在研究以较少的排放和较低的价格，从煤炭中获取最大功军电力的方法。他们已经提出了燃料电池／燃气涡轮机的复合。其中第一个已经在美国加利福尼亚大学校园里成功使用了四个多月的时间。

Making the most of coal

With over 50 per cent of US power being generated from coal it is clear the adoption of renewable energy will be a very slow process. In the meantime scientists are working on ways to capture the maximum amount of power from coal with less emissions and for a fraction of the price. They have come up with a fuel cell/gas turbine hybrid. The first of which, has successfully empowered a university campus in California. US, for over four months.
