To efficiently generate electric power.

A statistical information calculation part 257 calculates an angular dependence power generation amount of solar energy generation and an angular dependence power generation amount of wind energy generation, and adds them to calculate the angular dependence amount of the total power generation amount of the wind and solar energy generation device 100. An attitude control part 258 controls a fin operation part 261 or a body operation part 262 based on the angular dependence of the total power generation amount obtained like this, and controls the attitude of the wind and solar energy generation device 100 so that the total power generation amount becomes the maximum as an example. The apparatus is applicable to a control apparatus or the like for controlling the attitude of the power generation device.
