Canadian phantom (standby) power cost calculator. Identifies and quantifies electricity wasted by devices in standby mode. NRCan estimates phantom load accounts for 5% to 10% of residential electricity use. Common energy vampires: cable box (25W), game console (10W standby), desktop computer (5W sleep), microwave display (3W), chargers (1-5W). Average Canadian home wastes 50 to 100 kWh per month on phantom loads, costing $60 to $180 per year depending on province. Smart power strips and Energy Star certified devices reduce phantom load by 50% to 75%.

Formula
Each device plugged in draws a small amount of power even when switched off. This standby power runs 24 hours a day, 365 days a year. The calculator sums the standby wattage of all your devices and multiplies by 8,760 hours to find annual energy waste.
Canada FAQs
How much does phantom power cost the average Canadian home?
NRCan estimates that phantom power costs the average Canadian household $100 to $200 per year. In Ontario at 10.3c/kWh, a typical home wastes approximately 75 kWh per month on standby loads, costing $93 per year. In Nova Scotia at 15.5c/kWh, the same phantom load costs $140 per year. Nationally, phantom power wastes over $1 billion in electricity annually.
What devices use the most phantom power?
The biggest phantom power consumers are: cable or satellite boxes (25 to 35W even when "off"), game consoles like PlayStation and Xbox (8 to 15W in standby), desktop computers in sleep mode (3 to 10W), home audio receivers (5 to 15W), and older televisions (5 to 10W). A single cable box left plugged in uses more standby power than an Energy Star refrigerator uses in total.
Do phone chargers use power when not charging?
Yes, but very little. A modern phone charger draws 0.1 to 0.5 watts when plugged in without a phone. Over a year, that costs less than $1. However, older or low-quality chargers can draw 1 to 5 watts. The larger concern is laptop chargers (3 to 8W), which cost $3 to $8 per year in standby.
How can I reduce phantom power in my home?
Use smart power strips that cut power to devices when the primary device is turned off. Unplug chargers when not in use. Replace old cable boxes with streaming devices that use less standby power. Choose Energy Star certified electronics, which have strict standby power limits. Enable power-saving modes on game consoles and computers. These steps can reduce phantom load by 50% to 75%.
Are smart power strips worth buying in Canada?
Yes. A smart power strip costs $25 to $50 and can save $30 to $60 per year by cutting phantom power to entertainment centres and home office setups. For a home entertainment system (TV, cable box, game console, sound bar), a smart strip saves approximately $40 to $60 per year. The payback period is typically 6 to 12 months.
