1. What is the Energy Savings Calculator?

The Energy Savings Calculator estimates the monetary savings achieved by reducing energy consumption. It calculates the difference between old and new energy usage multiplied by the cost per kWh.

2. How Does the Calculator Work?

The calculator uses the energy savings formula:

Where:

• \( E_{old} \) — Old energy consumption (kWh)
• \( E_{new} \) — New energy consumption (kWh)
• \( C \) — Cost per kWh ($/kWh)

Explanation: The equation calculates the monetary savings by multiplying the energy reduction (in kWh) by the cost per unit of energy.

3. Importance of Energy Savings Calculation

Details: Calculating energy savings is crucial for evaluating the financial benefits of energy efficiency measures, making informed investment decisions, and tracking sustainability goals.

4. Using the Calculator

Tips: Enter old energy consumption in kWh, new energy consumption in kWh, and cost per kWh in $/kWh. All values must be valid (positive numbers).

5. Frequently Asked Questions (FAQ)

Q1: What if my new energy consumption is higher than old?
A: The calculator will show negative savings, indicating increased energy costs rather than savings.

Q2: Can I use different currencies?
A: Yes, as long as you consistently use the same currency for the cost per kWh input.

Q3: What time period should the energy consumption cover?
A: Ensure both old and new energy values cover the same time period (e.g., monthly, yearly) for accurate comparison.

Q4: Are there limitations to this calculation?
A: This calculation assumes constant energy rates and doesn't account for tiered pricing, demand charges, or time-of-use rates.

Q5: Can this be used for commercial energy savings?
A: Yes, the formula works for both residential and commercial energy savings calculations.
