What is Energy Efficiency?

Energy efficiency refers to the ability of an appliance or system to perform its intended function while consuming the least amount of energy possible. It is all about maximizing the output we get from the energy we put in. In other words, energy efficiency is about getting more bang for your buck when it comes to using energy.


Energy efficiency can be defined as the ratio of useful energy output to the total energy input. It is a measure of how effectively an appliance or system converts energy into the desired outcome, whether it is cooling a room, heating water, or powering a device. The higher the energy efficiency, the less wasted energy and the better the performance.

Importance of Energy Efficiency

Energy efficiency is of utmost importance for several reasons. Firstly, it helps conserve energy resources and reduces our dependence on fossil fuels, which in turn mitigates climate change and reduces greenhouse gas emissions. Secondly, it helps lower electricity bills, as using energy-efficient appliances consumes less energy and reduces overall energy consumption. Lastly, energy efficiency promotes sustainable living by extending the lifespan of our energy resources and preserving them for future generations.

Understanding Energy Efficiency Ratio (EER)

The Energy Efficiency Ratio (EER) is a measure of how efficiently an air conditioning system or appliance converts electrical energy into cooling output. It is an essential metric to consider when choosing an air conditioner or any other cooling device as it directly affects energy consumption and performance.


EER can be defined as the ratio of an air conditioner’s cooling capacity to the amount of electrical energy it consumes. The higher the EER, the more cooling output the device produces for a given amount of electricity consumed. EER is commonly measured in British thermal units per watt (BTU/W), and the higher the EER rating, the more energy-efficient the appliance is.

How EER is Calculated

To calculate the Energy Efficiency Ratio (EER), divide the cooling capacity of the appliance in British thermal units (BTUs) by the power input in watts. The formula is as follows:

EER = Cooling Capacity (BTUs) / Power Input (Watts)

By comparing the EER of different models, you can determine which one offers the most energy-efficient cooling option.

Interpreting EER Ratings

EER ratings typically range from 8 to 12 or higher. Higher EER ratings indicate better energy efficiency. For example, an air conditioner with an EER of 12 will provide more cooling output per watt of electricity consumed compared to a unit with an EER of 8.

When comparing EER ratings, it’s important to note that a higher EER rating may correspond to a higher initial cost. However, the long-term energy savings can outweigh the initial investment.
