The Energy Efficiency Formula

Before we dive into the calculator itself, let’s understand the fundamental formula that underlies the concept of energy efficiency:

Energy Efficiency (%) = (Useful Energy Output / Total Energy Input) * 100

In this formula, you calculate the efficiency of a system in terms of energy. The key components are:

  • Useful Energy Output: This is the energy you obtain as the desired output from a system. It’s the energy that fulfills your intended purpose, such as light from a bulb or heat from a furnace.
  • Total Energy Input: This represents the total amount of energy you put into the system, often measured in the same units as the useful energy output.

The result of this formula is expressed as a percentage, which indicates how efficiently a system converts input energy into useful output energy. A higher percentage signifies greater energy efficiency, which is an aim in most applications.

Example of Energy Efficiency Calculator

To illustrate this concept, let’s consider an everyday scenario: your home’s heating system. Imagine you have a furnace that consumes 1000 kilojoules (kJ) of natural gas to produce 800 kJ of heat energy. Applying the energy efficiency formula:

Energy Efficiency (%) = (800 kJ / 1000 kJ) * 100 = 80%

This means your furnace operates at 80% energy efficiency, indicating that 80% of the energy input is converted into useful heat output, while 20% may be lost as waste or unused.
