Frequently Asked Questions

What is a kWh?

A kilowatt-hour (kWh) is the standard unit for measuring electricity consumption. It equals using 1,000 watts of power for one hour.

How do I find my electricity rate?

Check your electricity bill — the rate is usually listed as a cost per kWh. Select your country and the calculator auto-fills the average rate, which you can adjust.

How is CO₂ calculated?

Each country has a grid emission factor (kg CO₂ per kWh) based on its energy mix. The calculator multiplies your kWh usage by this factor to estimate carbon emissions.

What does the Impact Simulator do?

It shows how much money and CO₂ you could save by making specific changes — like switching to LED bulbs, upgrading to inverter AC, or using BLDC fans.

Are the appliance wattages accurate?

The presets use typical average wattages. Your actual appliance may differ — check the label or manual for the exact wattage.
