Searching for energy-efficient fridges

The Maldives is the first country that aims for carbon neutrality in the world. With this in mind, the EPG has participated in the discussion of some of the questions stated in the Maldives CO2 forum (http://maldives.co2.org/) and has contributed with some of its experience in the field of energy efficiency.

Transition from 100% diesel towards renewable energy carries problems such as shifts between the demand and production power profiles. To tackle this, one of the fronts to reduce energy consumption is to use appliances that are more efficient.

In this context, special interest is devoted to refrigeration devices, as these are one of the main causers of grid stress. Some questions extracted from the forum that indicate the concerns on fridges are:

“What are the most energy efficient domestic fridges available today, and what is the cost premium for adopting them?”

“Are there any fridges or freezers that can shift demand from day to night?”

These two topics have been discussed within EPG and a small study was carried out to compare refrigerators’ energy-efficient and prices in the market around the world. Data recollection was carried out considering a “fridge-freezer” (capacity: 300 L aprox.). Each member of EPG chose one fridge sold in the UK and another from their home country (there is almost one person from every continent in EPG!).

As shown in the graph the general trend indicates, as expected, an increase of cost with increasing green-technology. Island-countries such as Cyprus and Malta that could have similar logistics on transportation than the Maldives, present the most expensive appliances. Because of the more expensive costs, a “rewarding” system may be needed to encourage consumers to replace old refrigerators by new A+++ ones (the lowest energy-consuming according to the EU classification).
