①
Electric Charge Measurement
Please note that the average electric charge of an average household (with an electric power usage rate of 300
kWh/month) is KRW168/kWh.
Ex. Electric charge (KRW
￦
) = 1 kWh × 168 (
￦
)
* The electric charge unit can be modified using the “Setting” key.
②
CO
2
Emission Amount Measurement
The allowable amount of fossil fuel (petroleum, coal) CO
2
emission for 1kWh power generation is 0.424kg (according to
the 2005 research data obtained by Korea Institute of Energy).
Ex. Amount of CO2emission(Kg) = 1 kWh × 0.424 kg
※
As the bases of the CO2 emission amounts are different, modification can be done using the “Setting” key.
