And so it takes a very large footprint on the land, a very large footprint in terms of materials, five to 10 times what you'd use for nuclear, and typically to get one gigawatt of electricity is on the order of 250 square miles of wind farm.
它需要在地面上占用大量的面积 巨大的面积也就意味着巨大的物质消耗 所占用的面积是我们用于核能的5 至10 倍， 尤其是，为取得10亿瓦特的电力 我们需要250平方英里 的风力电厂。
