To provide a system for management of natural energy, capable of strictly managing green power as well as electrical power selling and purchasing.
The system includes: a power generation unit 1 that generates power using natural energy; a generated power watt-hour meter 3 that measures the amount of power generated at the power generation unit; a selling power watt-hour meter 4 that measures the amount of power used for power selling of the power generated at the power generation unit; a green power computation unit 11 that determines the amount of green power by subtracting the amount of power measured at the selling power watt-hour meter from the amount of power measured at the generated power watt-hour meter; a setting unit 14 for setting a desired amount of green power; and a control unit 15 that controls the power consumption of a load so that the amount of green power computed at the green power computation unit becomes closest to the amount of green power set at the setting unit.
