1. What is a Gas Electricity Cost Conversion Calculator?

Definition: This calculator converts gas energy to equivalent electricity cost based on electricity rates and system efficiency.

Purpose: It helps energy professionals and consumers compare gas energy usage to equivalent electricity costs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \(\text{Cost\_elec}\) — Electricity cost ($)
• \(\text{Gas\_E}\) — Gas energy (kWh)
• \(\text{Rate\_elec}\) — Electricity rate ($/kWh)
• \(\text{Efficiency}\) — System efficiency (decimal, 0-1)

Explanation: The gas energy is multiplied by electricity rate and divided by system efficiency to account for conversion losses.

3. Importance of Cost Conversion

Details: This conversion helps in energy planning, cost comparisons between gas and electric systems, and efficiency analysis.

4. Using the Calculator

Tips: Enter gas energy in kWh, electricity rate (default $0.12/kWh), and system efficiency (default 0.85). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why include efficiency in the calculation?
A: Efficiency accounts for energy losses when converting between gas and electricity systems.

Q2: What's a typical efficiency value?
A: Most systems range from 0.7 to 0.9, with 0.85 being common for modern systems.

Q3: How do I convert gas volume to kWh?
A: Multiply gas volume (in cubic meters) by calorific value (typically 10.5-11.5 kWh/m³).

Q4: Where can I find my electricity rate?
A: Check your utility bill or contact your electricity provider for current rates.

Q5: Can this be used for renewable energy comparisons?
A: Yes, but efficiency values may differ significantly for renewable systems.
