Good power density means a shape like a peanut butter jar, easy to fill or empty; low power density is more like a wine jug with a narrow neck.

电能密度好的就像花生酱罐子口，很容易装满或倒空；电能密度差的就像窄瓶口的酒壶。

Those numbers explain why power density matters so much: if you start with a source that has low power density, you have to compensate for that low density by utilizing more resources such as land, steel, and ultra-long transmission lines.

If a source has low power density, then it will likely require too much real estate, material or space to provide the power that we demand at prices we can afford or in the vast quantities that the world needs.
