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。

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.

例如，在苏格兰，风力涡轮机为95%的家庭提供充足的电力。

In Scotland, for example, wind turbines provide enough electricity to power 95 percent of homes.

因此在多风的日子，最便宜的电力来自风力涡轮。

So on a windy day, the cheapest power comes from wind turbines.
