1. What Is The Energy Savings Calculation?

The Energy Savings Calculation estimates the financial savings achieved by reducing energy consumption through efficiency improvements. It compares old consumption levels with new, more efficient consumption levels.

2. How Does The Calculator Work?

The calculator uses the formula:

\[ Savings = (Old\ Consumption - New\ Consumption) \times Cost\ per\ Unit \]

Where:

Explanation: This formula calculates the monetary savings by multiplying the reduction in energy consumption by the cost per unit of energy.

3. Importance Of Energy Savings Calculation

Details: Calculating energy savings helps quantify the financial benefits of efficiency improvements, supports investment decisions in energy-saving technologies, and demonstrates environmental impact reduction.

4. Using The Calculator

Tips: Enter old and new consumption values in consistent units (kWh or therms), and provide the cost per unit in dollars. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for consumption?
A: Use consistent units throughout - either kilowatt-hours (kWh) for electricity or therms for gas consumption.

Q2: How do I find my cost per unit?
A: Check your energy bill for the rate per kWh or therm. This is typically listed in the charges section.

Q3: Can this calculator handle different time periods?
A: Yes, but ensure all consumption values are for the same time period (e.g., monthly, annually) for accurate comparisons.

Q4: What if my new consumption is higher than old?
A: The calculator will show negative savings, indicating increased energy costs rather than savings.

Q5: Are there other factors affecting energy savings?
A: Yes, factors like seasonal variations, equipment efficiency changes, and usage patterns can affect actual savings beyond simple consumption differences.
