1. What is Energy Efficiency?

Energy efficiency (η) measures how effectively energy is converted from one form to another. It represents the ratio of useful energy output to total energy input, expressed as a percentage. Higher efficiency indicates less energy waste.

2. How Does the Calculator Work?

The calculator uses the energy efficiency formula:

\[ \eta = \frac{\text{Useful Energy}}{\text{Total Energy}} \times 100\% \]

Where:

\( \eta \) — Energy efficiency (%)
Useful Energy — Energy that performs the desired work (kWh)
Total Energy — Total energy consumed or input (kWh)

Explanation: This formula calculates the percentage of input energy that is converted into useful output, with 100% representing perfect efficiency (no energy loss).

3. Importance of Energy Efficiency

Details: Energy efficiency is crucial for reducing energy costs, minimizing environmental impact, conserving resources, and improving sustainability. It's a key metric in energy management and conservation programs.

4. Using the Calculator

Tips: Enter both useful energy and total energy in kilowatt-hours (kWh). Useful energy must be less than or equal to total energy. Values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is considered good energy efficiency?
A: Efficiency values vary by application. Generally, 80-95% is excellent for most systems, though some processes may have lower typical efficiencies.

Q2: Why can't efficiency exceed 100%?
A: Efficiency above 100% would violate the law of conservation of energy, meaning more energy output than input, which is impossible.

Q3: What are common causes of energy inefficiency?
A: Heat loss, friction, resistance, incomplete combustion, and system leaks are common causes of energy waste and reduced efficiency.

Q4: How can I improve energy efficiency?
A: Regular maintenance, upgrading to efficient equipment, proper insulation, and optimizing system operations can improve energy efficiency.

Q5: Is this calculator specific to Nova Scotia?
A: While named for Nova Scotia, the energy efficiency calculation is universal and applies to energy systems worldwide.
