What is an average electricity cost per kWh?

In the United States, residential rates average around $0.16 per kWh, while European rates typically range from €0.25 to €0.40 per kWh.

Which home appliances consume the most electricity?

Heating, ventilation, and air conditioning (HVAC) systems, water heaters, clothes dryers, and electric ovens are the largest energy consumers.

What is phantom or standby power?

Many electronics draw 1-10W of power even when turned off to keep sensors and clocks active; using smart power strips can eliminate this vampire draw.
