How much am I spending on electricity right now?
The energy home screen displays the current cost of the electricity you are using in $ per hour. The cost per hour lets you know how much it will cost if you keep using electricity at the current rate for one hour.
Because your current electricity use is used to calculate the hourly rate, whenever there is a change of the electric load in your house, the hourly rate will change. You can reduce how much you spend on electricity by turning off/unplugging unnecessary appliances and lights.
