Take , for example , the intermittency of wind power .

以风能的间歇性为例说明。

The main problem with both wind and solar energy is not their cost ( which is falling satisfactorily with every passing year ) but their intermittency .

风能与太阳能发电装置的造价每年都在持续下降，因此使用它们的主要问题不是成本，而是无法持续发电。

For grid operators trying to balance a portfolio of different power sources , intermittency is no longer an abstract statistical anomaly , but determines whether they can keep the lights on .

因为输电网的经营者设法平衡不同能源的组合，中断不在是一个抽象的数据上显示的不正常，而是取决于是否能让灯泡一直亮着。

With increasing use of smart meters , which mitigate the problem of intermittency that plagues renewable forms of energy , demand for rooftop installations should grow strongly in these places .

随着智能电表的使用增多，这就缓解了困扰可再生形式能源间断性供电的问题，这些地方的屋顶安装需求将会激增。
