Energy, carbon emissions and cost calculator: enter power rating in Watt, enter hours use per day/week/month, standby power, and see what you pay, and how much CO2 you generate. Or, choose from the built-in list of more than 100 appliances, and see what they cost you per day, month and year.

You can easily make an inventory of all appliances in your house, per room, and see where you can save. What are the unexpected power consumers?
