Countries with excellent wind energy sources decide on national projects for the development of wind energy. Ten percent of the land area will be devoted to 1.5 kW wind energy per person, roughly the amount of electricity used by one person in an industrialized country.  2 MW wind turbine with a rotor of 80 m diameter is placed in the average layout space of the figure. Depending on the wind conditions, the average output is 650 kW per turbine. Calculate the maximum density of a single sphere consistent with this business plan. Align geographic information with Germany, Spain, India and Denmark (they all have active wind power programs), and discuss the possibilities for achieving this goal in each of these countries.

Expert Solution
Step 1

Figure 10.18 (ideal) provides the average crosswind distance and wind turbine spacing.

As a function of rotor diameter, the distance between wind turbines in a wind farm is displayed.

Downwind wind turbines will be spaced 8 times the diameter of their rotors apart.

lavg=8d

Here, d is the diameter of the wind turbine.

Substitute 10 m for d.

lavg=8×10 m       =80 m

The average crosswind spacing will be 3 times the rotor diameter.

bavg,cross wind=3d

Here, d is the diameter of the wind turbine.

Substitute 80 m for d.

bavg,cross wind=3×80 m                        =240 m

Calculate the land area required.

Aland=lavgbavg,cross head

Here, Aland=lavgbavg,cross head is the average crosswind spacing and lavgthe average spacing of the wind turbines downwind.

Substitute 800 m for lavg and 240 m for bavg, cross head.

 

Aland=800 m×240 m         =192000 m2×1 km2106 m2         =0.192 km2
