Many of us have heard of the term energy efficiency, but… Do you really know what it means? This term refers to the ability to obtain the best results in any activity using the best possible amount of energy resources.


Energy efficiency aims to protect the environment by reducing energy intensity, getting users into the habit of consuming only what they need. Today, the pursuit of Energy Efficiency has become a priority for governments around the world, as traditional energy sources are becoming increasingly expensive, limited and also generate dependence on the foreign market.

At a productive level, companies and the different public administrations are implementing measures and initiatives to commit to renewables and to be more sustainable. In addition, they need to take measures to obtain energy efficiency certificates, which are so important nowadays.

To calculate and measure energy efficiency, one of the main standards is ISO 14001 – Environmental Management Systems (EMS). This is an international standard that allows companies to demonstrate their commitment to environmental protection by managing the environmental risks associated with their activities.

Obtaining this certificate offers companies, organisations and administrations many advantages as it confirms that they are working in a structured and strategic way to reduce their environmental impact.

And now …. What if we want to transfer energy efficiency to the home?  From Nara Solar we leave you some tips to be more efficient at home.

Use energy-efficient appliances: the energy label on household appliances allows us to quickly and easily see their energy efficiency. This is based on a letter scale (from A to D) and a colour scale (from green to red), ranging from the most to the least energy efficient.

Make responsible use of air conditioning and heating: in summer because it is hot and in winter because it is cold… we end up using these appliances, which account for between 60 and 70% of household electricity consumption. The solution? Good home insulation, especially in doors and windows, can help to conserve the temperature better.

Choose the right bulbs: lighting accounts for 10% of household electricity consumption. Changing incandescent and fluorescent bulbs for energy-saving LEDs offers advantages: they are safer and less polluting.

Reduce, reuse and recycle: implementing the so-called “circular economy” at home is one of the most effective ways to contribute to global energy efficiency. Do you find it difficult? To make it easier you can set aside a small space in your kitchen to separate waste while you are cooking or cleaning.

These small changes cost very little and can do a lot for your economy and the environment. Start being more energy efficient!
