If you compared Detroit with a city of a Northern European example -- and Munich is not a bad example of that, with the greater dependence on walking and cycling -- then a city which is really only twice as dense, is only using one-tenth of the energy.
如果你将底特律跟北欧的一个城市相比较， 慕尼黑算是不错的选择， 慕尼黑大量依赖走路和骑脚踏车， 那么这个密度多了一倍的城市， 却只使用底特律十分之一的能源。
