When viewing the city it is kind of hard to pin point an energy flow. I suppose in one aspect, one could see the motion of cars and trains in and out of the city as an energy flow. In the morning, for the Twin Cities area and Minneapolis in particular, cars commute in from all directions into the city. Its as though there is this huge amount of energy being pumped into the city that makes it run and function in the world. After the typical work day, a lot of cars and people leave the downtown area. This could be viewed as a release of energy built up throughout the day. Energy flows in and flows out on the day to day basis.

Another thing to look at would be the rivers and drainage systems. Energy flows down and into the city with rain and snow and they exit the city through the drainage systems and flow out of the city through the rivers current. The river also brings things into the city from runoff and things like that. It enters and leaves the city in one direction and flow.
I suppose when you look at the city in a birds eye view, the circulation of energy could be viewed as a circle. People, cars and products flow and move into the city and flow right back out in a continuous flow and motion, just like a circle. Its as though there is no real beginning or end. Its just a continuous stream that will never dry up.
