Overview: Aero Island, Denmark, p. 449

As you've read in this chapter, Aero Island gets all its energy from renewable sources. All the home space heating for the major town of Marstal is provided by the array of solar collectors seen in this place marker and in figure 20.1 in the textbook. The gray rectangles just west of the place marker are the array of thermal solar collectors shown in figure 20.1. Water heated in glass-covered panels is used to heat the neighboring town of Marstal. The white cylinder (upper left) and gray rectangle (lower left) store thermal energy, so that heat collected in warm months can be distributed during cold months.

The island, like the rest of Denmark, also produces electricity using wind generators, shown in the opening photograph for this chapter, but these windmills are not visible from above.

You'll notice that Marstal is a fairly small, compact town. Why is that important for a district heating scheme such as this?
A)The heating scheme is so wasteful, it's critical that the town be small and compact or it won't work at all.
B)It is important because, if the heating scheme fails, there will be a smaller population of justified complainers.
C)Because the town is small and compact, it's relatively efficient to pipe hot water to all buildings.
D)Small towns tend to have simpler regulatory barriers to overcome.
E)Paradoxically, towns that are rural and widespread would be much more appropriate for a district heating scheme such as this.

Using the ruler tool, measure the size of the entire rectangular solar array.
A)The solar array is approximately 10 m x 15 m.
B)The solar array is approximately 10 m x 30 m.
C)The solar array is approximately 50 m x 150 m.
D)The solar array is approximately 120 m x 300 m.
E)The solar array is approximately 300 m x 500 m.

What is the predominant land use on Aero Island?
A)Agricultural
B)Recreational
C)Industrial
D)Habitational
E)Wilderness
