A: Your electricity bill typically shows your energy consumption in kilowatt-hours (kWh) for the billing period.
Q2: How do I determine the cost per kWh?
A: The cost per kWh is usually listed on your electricity bill. You can also contact your utility provider for this information.
Q3: Does electricity cost vary in California?
A: Yes, electricity rates in California vary by utility provider, time of use, and sometimes by season or consumption tier.
Q4: Can I use this for solar energy calculations?
A: Yes, you can use this calculator to estimate savings from solar energy by comparing your current electricity costs with projected solar energy costs.
Q5: Are there additional fees not included in this calculation?
A: Some utilities charge additional fees, taxes, or demand charges that may not be reflected in the simple per-kWh rate. Check your bill for complete cost information.
