Quick Answer
Most Sri Lankan homes can reduce bills by 10% to 30% by tightening AC/fan settings, reducing standby waste, and replacing one inefficient major appliance.
Key Factors and Savings Table
| Action | Typical monthly impact |
|---|---|
| AC at 26 C + fan support | 8% - 15% |
| Replace old fridge with efficient model | 5% - 12% |
| Shift ironing/washing to planned batches | 3% - 8% |
Savings depend on home size, weather, and appliance condition.
Example Calculation
Current usage: 220 kWh/month at LKR 55/kWh
Current variable cost: 220 x 55 = LKR 12,100
If you save 18% usage, new usage is about 180 kWh, variable cost about LKR 9,900.
Actionable Tips
- Audit top kWh devices before buying small gadgets.
- Use timer control for water heating where possible.
