2. In areas where the wind dies down, backup electricity from a utility company or from an energy storage system becomes necessary. 在风能不稳定的一些地区，需要供电事业公司或者能量储存系统来提供备用电能。
3. The hydrogen gas could then be fed into a storage system and used to generate electricity when additional or backup power is needed. 然后可以将氢气输入到存储系统中，并在需要附加或备用电源时用于发电。
4. Backup power could also be provided by linking wind farms with a solar cell, with conventional or pumped-storage hydropower, or with efficient natural-gas-burning turbines. 将风力发电厂与太阳能电池、常规或抽水蓄能的水电或高效的天然气涡轮机连接起来，也可以提供备用电力。
5. Although many of these storage media have high capacity, a backup tool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads. 尽管这些存储介质中有许多具有高容量，但具有压缩能力的备份工具是一大优势，它消除了多个磁盘或大型上传的不便。
