📊 Efficiency Verdict
Reducing consumption by 10–15% effectively lowers your bill in every state market.
Understanding your bill requires looking beyond the headline rate displayed in state comparison tables. Most residential customers pay a fixed customer charge—usually $10 to $20 monthly—plus a variable per-kWh consumption charge. Some utilities, particularly in California and Arizona, structure tiered pricing where the first 500 kWh cost 15 cents, while usage above 1,000 kWh jumps to 25 or 30 cents, penalizing heavy consumption.
