Is your $0.12/kWh just your supply cost or does it also include the cost to deliver/distribute that electricity to your house? Because your actual cost maybe higher.
Exactly. My 8 cent power in more like 10-11 cents/kWh once I add up customer fee, fuel delivery, taxes, etc.
Divide the total $ amount of your electric bill with the total kWh usage and that's your true cost.
For example, $400 monthly electric bill with 2500kwh total monthly usage: 400/2500=$0.16. So your true cost is 16 cents/kWh, not the 12 or whatever cents listed on your bill.
