The power output of a wind power plant is stochastic, which is determined by the wind and wind turbine generators.

风资源最大的特点就是风速的大小和方向的随机性，风的这种特性决定了风力发电厂输出功率的随机性。

In the right climate, both can be deployed at "utility scale," meaning that if it's breezy or sunny enough, a wind or solar farm can produce as much power as a coal-fired plant.

在气候适宜的时候，这两者都可以达到“实用水平”。也就是说，如果有风或者是太阳足够好的话，一个风能或者太阳能发电厂可以达到一个煤电厂的发电水平。

Simple math shows that a marginal gas or oil well has a power density at least 22 times that of a wind turbine while a nuclear power plant has a power density that is more than 8 times that of a solar photovoltaic facility.

For example, Lisa McNeilly, a collaborator on the report, said it might be cheaper for a rural town that currently does not have electricity to construct a wind or solar energy facility in the village instead of wiring in electricity from a power plant located a hundred miles away.

At any rate, a group of municipal power companies in the American Midwest reckon that building a wind-powered compressed-air plant to take advantage of the blustery Great Plains will be worthwhile.
