Wind and solar generation tend to be distributed because of the low density of the natural energy they collect.

由于它们采集天然能源的地点非常分散，因此风能和太阳能的发电也呈现出分散状态。

Because wind energy has lower density, instability and randomicity, control is vital for safety and efficiency of a large-scaled wind turbine.

由于风能的能量密度低，具有不稳定性和随机性，控制技术是大型风力发电机组安全高效运行的关键。

Heilongjiang also has great potential for wind power, with an average wind energy density of 200 watts per square metre.

黑龙江省有着巨大的风电发电潜力，拥有每平方公里平均风力电能密度达20 0瓦。

While the residents of Samso can take advantage of their island's blustery weather, open spaces and low-population density to be carbon neutral, the success of wind energy on a global scale may come down to simple economics.
