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。

At the moment, however, there are only two compressed-air energy-storage plants in the world (one in America and one in Germany), and neither was built to make use of wind power.

然而，截至目前，全世界仅有两个压缩空气发电站(一个在美国，另一个在德国)，但都不是利用风能来压缩空气的。

New technology for storage and transmission make wind power cheaper than solar, but it is still 50% more expensive than coal-powered electrical plants.

新的存贮与传输技术使得风能比太阳能在成本上更低廉，但是它仍然比传统的燃煤发电厂高出了50%的成本。

Also, since the necessarily erratic nature of wind power necessitates the development of energy-storage technologies to guarantee continuous supply, wind power can also act as a spur to the development of a hydrogen economy in which cars no longer require petroleum fuel.

ECONOMIST: Regulating radio

The need to engineer energy storage equipment that could work well with solar or wind power plants has prompted many private and public investments in battery and other storage technologies.

FORBES: Feds Fund Four Projects To Simplify Solar Gear Designs and Predict Power Output

The Infrastructure Planning Commission (IPC), a quango with the ability to force through important national projects over the objections of locals, is supposed to make it easier to build power lines, storage plants, wind farms and the like.
