其一直在改进这项技术，其中包括开发可以储存电力的路边电池。

It has been improving the technology, including developing roadside batteries that can store the electricity.

那也就意味着除非有电力储存上的技术突破，风能和太阳能很可能在我们总的能源需求中只能做出占百分比个位数的少量贡献。

That means that barring a breakthrough technology in electricity storage, wind and solar are likely to contribute only small - that is, single-digit - percentages of our overall energy needs.

风力发电，是目前各种再生能源中最成熟的技术，也被广泛的利用，但我们必须寻找到在无风时储存电力的方法。

Wind power, the most mature renewable technology, is growing fast, but we need to find a way to store electricity when the breeze isn't blowing.
