Electrical consumption cost is the amount of electricity consumed by the household appliances. It is measured in kWh.
HOW DOES IT MEASURED
The electric company used a device to measured the amount of electric of each houses in the area. This is called the meter.
Digital meter
Every end of the month, they read the meter and using their device they instantly give the electrical statement.
All appliances have the same electrical consumption (Watt). Look at the picture below:
The refrigerator is the 24/7 on in all appliances and it consumed 727W per hour, think about it. The television (flat screen) consumed only 133 W/h not like the tube TV consumed almost 330W/h.
HOW TO CALCULATE THE MONTHLY USED OF ELECTRICITY
The formula to compute the monthly electricity consumtion is:
Wattage of appliance x average hrs used in a day x no. of days in a month that it is used x the electrical cost
For example the flat screen TV consumed 133W and you used it 8 hrs every weekends but on weekdays you used it 3 hrs only. The electrical cost is 7 pesos per KWh To solved this problem, used the table to know the wattage of this appliance and then compute how many days in weekends and weekdays in a month. Then solved it using the formula.
For weekends
133W x 8hrs = 1064Wh or 1.064KWh
1.064 x 8 days = 8.512KWh in a month
For weekdays
133W x 3hrs = 399 W
399W x 22 days =8.778KWh in a month
Sum it up
8.512 + 8.778 =17.29
17.29 x 7 = 121. 03 pesos
The cost is 121.03 pesos. This is only in your TV not included the refrigerator iron and air conditioner.
TIPS TO LESSEN THE AMOUNT OF COST
1. Unplug the appliance is not in used. like the tv if it is in standby mode it also consumed electricity.
2. Using the washing machine and iron, create a schedule to used it for example once a week.
3. Before going to bed, check all the appliances if it is turn off /unplug and also turn down the thermostat of the refrigerator to lessen the cool.
4. Used only the rice cooker if it is needed, like you are busy for something and you can used this but if not you can used the stove or the coal to cook rice.
5. Used only the CFL to save more energy.
6. In case of brownout, Unplug all the appliance for safety and do not plug it immediately if the electricity came back.
7. If buying new appliances, look the Energy efficiency first before buying it.
8. Used only the computer or laptop in important things.
