Our CO2-studies

How much do our household appliances consume?

In our CO2-studies, we have been tracking for years how old are and how much energy our large household appliances consume, and how much energy could be saved by replacing old appliances.

Since 2006, since the launch of our energy efficiency campaign, the Cycle Michael program, we have been claiming that old energy-guzzler appliances consume much more than new, energy-efficient, modern machines. But how much more? To find out, we hired an internationally recognized market research firm, GFK Hungária Kft., and we looked at the numbers!

We were shocked by the results!

We found that 43% of the large domestic appliances in the Hungarian households were over 8 years old, but these appliances were responsible for ¾ of the total consumption!

Since then, we’ve been doing the survey regularly, and we’ve been tracking how much the situation has changed: how old are our appliances and how much they consume.

Some summary tables are also included here:

In the table below we can see the consumption of machines over 8 years old between 2009 and 2015:

It is clear from the table that if all large household appliances (refrigerators, freezers, washing machines and electric stoves) older than 8 years old were replaced in Hungarian households to a modern appliance, more than 2.5 million tons of CO2-emission reduction could be achieved. This is a huge theoretical potential! The main objective of the fight against climate change and global warming is to reduce CO2 emissions, and the solutions to increase energy efficiency are means to achieve this.

This is what the Otthon Melege Program’s replacement of large household appliances subprogram is based on. In this program, it is a definite purpose to stop using the very old, energy-guzzler appliances in households, because it is environmentally damaging to use them further.
