How Electricity Consumption is Calculated
Electricity consumption is measured in kilowatt-hours (kWh). One kWh means using 1000 watts for one hour.
Formulas
Daily Consumption (kWh):
(Wattage × Hours per Day × Quantity) / 1000
Monthly Consumption:
Daily kWh × 30 days
Monthly Cost:
Monthly kWh × Electricity Rate (₹/kWh)
Example
A 1500W AC running 8 hours daily:
- Daily: (1500 × 8) / 1000 = 12 kWh
- Monthly: 12 × 30 = 360 kWh
- Cost at ₹8/kWh: 360 × 8 = ₹2,880/month
Energy Saving Tips
Use LED Bulbs
Replace incandescent bulbs with LEDs. They use 75% less energy and last 25× longer.
Optimize AC Usage
Set AC to 24-25°C, use timer, and ensure proper insulation. AC consumes 40-50% of home electricity.
Unplug Devices
Devices on standby still consume power. Unplug chargers and electronics when not in use.
Choose Energy-Efficient Appliances
Look for 5-star BEE ratings. They cost more upfront but save significantly over time.
Regular Maintenance
Clean AC filters monthly, defrost refrigerator, and maintain appliances for optimal efficiency.
Use Natural Light
Maximize daylight usage. Open curtains during day and use task lighting instead of lighting entire rooms.
Frequently Asked Questions
What is the average electricity consumption per household?
In India, average household consumption is 200-300 kWh/month (6-10 kWh/day). This varies widely based on family size, appliances, and AC usage. With AC, consumption can reach 400-600 kWh/month.
How much electricity does an AC consume?
A 1.5-ton AC consumes 1.2-1.5 kW per hour. Running 8 hours daily costs ₹2,000-3,000/month at ₹8/kWh. 5-star rated ACs consume 20-30% less than 3-star models.
Why is my electricity bill so high?
Common reasons: excessive AC usage, old inefficient appliances, water heater left on, refrigerator in hot area, many lighting points, or faulty wiring. Use this calculator to identify high-consumption appliances.
What is a kWh and how is it different from kW?
kW (kilowatt) is power - how much electricity an appliance uses at any moment. kWh (kilowatt-hour) is energy - total electricity consumed over time. Example: A 1000W (1kW) appliance running for 1 hour uses 1 kWh.
How can I reduce my electricity bill by 30-40%?
Replace regular bulbs with LEDs, optimize AC temperature (24-25°C), use fans alongside AC, choose 5-star appliances, unplug devices, use solar water heater, and shift heavy loads to off-peak hours if on ToD tariff.
Does voltage fluctuation increase consumption?
Voltage fluctuations don't directly increase consumption but can damage appliances, reducing their efficiency over time. Use voltage stabilizers for sensitive equipment like AC, refrigerator, and TV.
Should I invest in solar panels?
If your monthly bill exceeds ₹3,000-4,000, solar can be cost-effective. Typical payback period is 4-6 years in India. Consider rooftop space, local sunlight hours, and available subsidies (₹14,588-₹78,000 for residential).
