1. What is the Energy Bill Calculator?

The Energy Bill Calculator compares the operating costs of gas vs electric stoves by calculating the energy costs based on BTU input, efficiency, and local utility rates.

2. How Does the Calculator Work?

The calculator uses these equations:

Where:

• \( BTU_{Gas} \) — British Thermal Units for gas stove
• \( Efficiency_{Gas} \) — Efficiency of gas stove (typically 0.35-0.45)
• \( Gas\ Rate \) — Cost per BTU of gas
• \( BTU_{Electric} \) — British Thermal Units for electric stove
• \( Efficiency_{Electric} \) — Efficiency of electric stove (typically 0.70-0.80)
• \( Electric\ Rate \) — Cost per kWh of electricity

Explanation: The equations account for the energy input, the efficiency of conversion to heat, and the local utility rates to determine actual operating costs.

3. Importance of Energy Cost Comparison

Details: Comparing energy costs helps consumers make informed decisions about appliance purchases and understand long-term operating expenses.

4. Using the Calculator

Tips: Enter BTU values for both stove types, their efficiencies (as decimals between 0 and 1), and your local utility rates. Typical gas rates are around 0.00001 USD/BTU and electric rates around 0.12 USD/kWh.

5. Frequently Asked Questions (FAQ)

Q1: What are typical efficiency values?
A: Gas stoves typically have 35-45% efficiency, while electric stoves have 70-80% efficiency.

Q2: How do I find my utility rates?
A: Check your utility bills or contact your local utility provider for current rates.

Q3: Why convert electric rate from kWh to BTU?
A: 1 kWh = 3412.14 BTU, so we divide the electric rate by this factor for accurate comparison.

Q4: Which is usually cheaper to operate?
A: Results vary by location, but gas is often cheaper where gas rates are low, despite lower efficiency.

Q5: Does this account for all cost factors?
A: This calculates only energy costs - installation, maintenance, and equipment costs are not included.
