Frequently Asked Questions (FAQ)

How do I find the wattage of my appliances?

You can find wattage information on the appliance label, user manual, or manufacturer's website. Common household items: LED bulb (10W), refrigerator (150W), laptop (50W), air conditioner (1500W). Our calculator includes preset values for most common appliances.

What's the difference between watts and kilowatt-hours (kWh)?

Watts (W) measure power (energy used per second). Kilowatt-hours (kWh) measure energy consumption (power × time). Electricity bills are based on kWh: 1 kWh = using 1000 watts for 1 hour.

Which appliances use the most electricity?

Typically, heating and cooling systems (AC, heaters), water heaters, clothes dryers, and refrigerators are the biggest energy consumers. Electronics and lighting usually consume less but can add up significantly.

Do appliances consume electricity when turned off?

Yes, many appliances have "phantom loads" or "vampire power" - they draw small amounts of power when turned off but still plugged in. Common culprits include TVs, computers, chargers, and kitchen appliances with digital clocks.

How can I reduce my electricity bill?

Effective strategies include: using energy-efficient appliances, unplugging devices when not in use, optimizing thermostat settings, using LED lighting, and reducing hot water usage. Our calculator helps identify your biggest savings opportunities.
