What is Kilowatt hours? (kWh)
kWh is a measure of how much electricity someone uses over a certain time.
kWh Model
Unlike the Amps model, kWh model will make sure that each customer is being billed for the exact amount of electricity he is using.
Older Models
In the older models, people are charged for the max Amps that is used regardless of the actual amount of kWh the customer is using.
KWH Calculation.
A 0.05 kW lamp used 10 hours daily for 30 days consumes 15 kWh/month.
Consumption (kWh) = Power (KW) × Hours/Day × Days/Month
= 0.05 × 10 × 30 = 15 kWh.
Key Tips for Summer Responsible Usage
Reduce your consumption and hence your bill at the end of the month by following the steps below.
Air Cooling Appliances
- Favor the use of air coolers over A/Cs where possible. This is because air coolers generally consume significantly less electricity for a very similar cooling effect.
- Set your A/C to a cooling temperature between 22-24 degrees Celsius. This allows you to save more electricity than if you were to put it on a lower cooling temperature.
- Whether you use an A/C or air cooler for cooling, consider putting it on a lower fan speed.
Boilers
- Set your boiler to manual and only switch it on when you need it. Keeping your boiler on all the time or setting it to automatic consumes more electricity. This is especially true in summer when hot water is less needed.
- Set your boiler to a heating temperature of 50-55 degrees Celsius. This allows you to save more electricity than if you were to put it on a higher heating temperature.
Smart Usage Habits
- Only switch on the electrical appliances which you need. For example, turn off the lights, A/C, air cooler, or any other appliances when you leave a room.
- Consider switching to inverter appliances when acquiring new appliances. These consume less electricity. Common appliances with inverter models include A/Cs, refrigerators, and washing machines.
Energy Efficiency Tips
- Clean your A/Cs and boilers at least once a year, to remove debris build-up and make them run efficiently. This is especially true for older appliances.
- Keep doors and windows shut when your A/C is switched on. This helps to avoid cool air from escaping, which means your A/C will have to work less hard.
- When acquiring new appliances, consider switching to A to A+ ratings. These are more energy-efficient.
Lamps
- Replace your normal light bulbs with LED light bulbs which use less electricity for the same lighting effect.
