- **Cheapest states**: $0.08-0.10/kWh (Louisiana, Oklahoma)
- **Most expensive**: $0.25-0.35/kWh (Hawaii, Connecticut)

Exemple Résolu

A home using 900 kWh/month at $0.15/kWh with a $12 monthly fixed charge.

  1. Usage charge: 900 * $0.15 = $135.00
  2. Monthly bill: $135.00 + $12.00 = $147.00
  3. Annual cost: $147.00 * 12 = $1,764
  4. Daily cost: $147.00 / 30 = $4.90
