To try and answer this question Iâve collected average electricity prices from 17 countries around the world, and converted them to $/kWh (US). All the data is based on average prices and exchange rates for 2011, and Iâve graphed them in US cents/kWh to keep it tidy.anadian electricity is cheap at 10 US cents per kilowatt hour, which is reflected in their high average electricity usage.
