@ryan@hachyderm.io There are more sides, Urbanised area's is only 10% of the land surface. Roughly 50% of the population lives there. The other half live in semi urban and rural area's. From my background I focus on energy supply. Planning is important for all. In the case of the future energy mix, urbanised area's are dependant for their energy supply from the rural area's. Especially for wind energy. Energy transportation lines are costly, so it has to be generated as most as possible close to urbanised area's.
