1. What is an Electric Savings Calculator?

Definition: This calculator estimates the monetary savings from reduced electrical energy consumption.

Purpose: It helps homeowners, businesses, and energy auditors evaluate the financial benefits of energy efficiency improvements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Savings \) — Monetary savings in dollars
• \( E_{old} \) — Old energy consumption (kWh)
• \( E_{new} \) — New energy consumption (kWh)
• \( Rate \) — Electricity rate ($/kWh)

Explanation: The difference between old and new energy use is multiplied by the electricity rate to determine cost savings.

3. Importance of Energy Savings Calculation

Details: Calculating potential savings helps justify energy efficiency investments and track performance of energy conservation measures.

4. Using the Calculator

Tips: Enter your current energy use, projected new energy use after improvements, and your local electricity rate (default $0.12/kWh).

5. Frequently Asked Questions (FAQ)

Q1: What if my new usage is higher than old?
A: The calculator will show $0 savings (negative savings are not displayed).

Q2: Where can I find my electricity rate?
A: Check your utility bill or contact your electricity provider for current rates.

Q3: Does this account for time-of-use rates?
A: No, this uses a flat rate. For time-of-use, calculate savings for each rate period separately.

Q4: How often should I recalculate savings?
A: Recalculate whenever your usage patterns change or electricity rates are adjusted.

Q5: Can this calculate annual savings?
A: Yes, input annual kWh values and the calculator will show annual savings.
